The Context Plus XP95 Zone Monitor powers and controls the operation of a zone of up to 20 Series 65 conventional fire detectors from a loop of Context Plus analogue addressable detectors and interfaces. FEATURESThe Zone Monitor is factory preset to return an analogue value of 16 when all detectors on the zone are in quiescent state and 64 when a detector changes to the alarm state. The Zone Monitor latches in the alarm state. 5.1k! end-of-line resistor is fitted to detector cables for open- and short-circuit faults. Alternatively, an active end-of-line monitor may be used in conjunction with diode bases and a capacitor of up to 50μF fitted at the Zone Monitor wiringterminals. In either case an analogue value of 4 is transmitted during open- or short-circuit faults. The Zone Monitor is fitted with a bi-directional short circuit isolator and will be unaffected by loop short circuits on either the loop input or loop output. ELECTRICAL CONSIDERATIONS The Zone Monitor is loop powered and operates at 17–28V DC with protocol pulses of 5–9V. MECHANICAL CONSTRUCTION The Zone Monitor is supplied with a backbox for surface mounting, and is also available without the backbox for flush mounting. Both versions are for indoor use only. Two LEDs, one red and one yellow, are visible through the front cover of the enclosure. The red LED is illuminated to indicate that a fire alarm condition has been detected on the zone wiring. The yellow LED is illuminated whenever the built-in isolator has sensed a short circuit loop fault. NOTES ON USE 1. Zone voltage is regulated to 19 ± 1V for any loop voltage greater than 22V. If the loop voltage falls below 22V, the zone voltage is approximately 1.5V below the loop voltage. It is important to ensure that under worst-case conditions, the zone voltage is above the minimum operating voltage for the conventional detectors. 2. Alarm conditions are latched internally by the Zone Monitor. It is therefore necessary to reset the alarm even if non-latching conventional detectors are used. 3. Manual call points can be located at any point in the zone wiring if active end-of-line monitoring with diode detector bases is used. If a 5.1k! resistor is used for monitoring, manual call points must be connected between the Zone Monitor and the first detector.

The signals from the optical smoke sensing element and the temperature sensor are independent, and represent the smoke level and the air temperature respectively in the vicinity of the detector. The detector’s microcontroller processes the two signals. The temperature signal processing extracts only rate of rise information for combination with the optical signal. The detector will not respond to a slow temperature increase – even if the temperature reaches a high level. A large sudden change in temperature can, however, cause an alarm without the presence of smoke, if sustained for 20 seconds.

The sight of a fire is always rejected or dismissed especially when the scale of it is large and if it has engulfed people and property. In this particular situation, the top priority is to ensure that minimal damage takes place and no human life is lost in this form of accident. Gone are the days when getting protection from such misshapening used to drive people in a big dilemma, but today in the 21’st century proper measures can be taken easily. The firefighting personnel are equipped with all sorts of gear and tools that enable them to penetrate in all forms of fire and reduce the loss in all forms. Having said this, still, it does not mean that one should relax and totally depend on the auxiliary features, especially when the life is at stake. Just due to this particular reason company like Agni Devices Pvt. Ltd. has fabricated a very sophisticated version of Wireless Alarm System.

We are an eminent and leading trader of waterproof manual call point. The Context Plus Waterproof Manual Call Point has an IP67 rating and is intended for outdoor applications or areas where water and dirt are a problem. It incorporates a short circuit isolator which will ensure its operation in the event of a short circuit fault on the loop. The Call Point is surface mountable and has an easily resettable element rather than a break glass. It also features a unique ‘Plug and Play’ installation concept designed specifically to reduce installation time. The call point utilises a terminal block, where all installation cabling is terminated. Its address is set at the commissioning stage by means of a seven-segment DIL switch. A single bi-coloured alarm LED is provided which is controlled independently of the call point by the control panel. The LED is illuminated red when the call point has been activated and amber/yellow to indicate a short circuit. Once activated, the Call Point can be reset by inserting the test key into the bottom of the unit until the key clicks into position, next remove the test key and push the front cover up until it clicks home.

We are providing a various types of products such as Water Leak Detection System Water Leak Detection Panel provides round the clock protection against unwanted water leakage with the help of water detection cable like SONTAY The water leak detection cable will be placed in distributed locations inside server room/Data Centers. These will be mounted on floors with provision to adjust the sensing of thin film of water. Each Cable is wired to the control panel. In the control panel, the water leak from each cable is monitored and in case of detection from any cable, an alarm is initiated. This alarm will be on as long as the water leak present across the cable. The water leak detection cable detect continuous presence of water across the cable. It detects leaks like condensate water overflow, chiller water leaks, plumbing line cracks, heating/cooling piping leaks, outside seepage & more before damage and downtime occurs.  

Context Plus XP95 temperature (heat) detectors have a common profile with ionisation and optical smoke detectorsbut have a low air flow resistance case made of self-extinguishing white polycarbonate. They monitor temperature by using a single thermistor network which provides a voltage output proportional to the external air temperature. The response to temperature increases of the standard temperature detec tor (part no: 55000-400IMC) enables the detector to be utilised as an EN54 Grade 2 heat detector. To provide a device for use in ambient temperatures of up to 55°C, a high temperature detector (part no: 55000-401IMC) is also available. This has similar characteristics to the standard temperature detector at 25°C but reaches a 55 count (alarm) at 90°C.

The Context Plus XP95 Switch Monitor is designed to monitor the state of one or more single pole, volt-freecontacts connected on a single pair of cables and to report the status to Context Plus compatible control equipment. FEATURESThe Switch Monitor provides four input states to the control equipment: ‘Normal’, ‘Fault’, ‘Pre-alarm’ and ‘Alarm’. The Switch Monitor has a red LED to indicate an alarm and two yellow LEDs to indicate a switch input wiring fault or a loop short-circuit wiring fault. The Switch Monitor is fitted with a bi-directional short-circuit isolator and will be unaffected by a single short-circuit on either loop input or output.

Our DIL Switch Addressed (DSA) Context Plus optical detector has a moulded self extinguishing white polycarbonate case designed to allow free entry of smoke while minimising the effects of dust contamination. Stainless steel wiper contacts connect the detector to the terminals in the mounting base. Within the case is a printed circuit board,The other side has the address capture, signal processing and communications electronics. An infra-red light emitting diode (IR LED) within the optical chamber is arranged at an obtuse angle to a photodiode. The photo-diode has an integral daylight-blocking filter. The IR LED emits a burst of collimated light every second.

The Context Plus XP95 multisensor detector contains an optical smoke sensor and a thermistor temperaturesensor whose outputs are combined to give the final analogue value. The multisensor construction is similar to that of the optical detector but uses a different lid and optical mouldings to accommodate the thermistor temperature sensor. The sectional view (below) shows the arrangement of the optical chamber and thermistor. The signals from the optical smoke sensing element and the temperature sensor are independent, and represent the smoke level and the air temperature respectively in the vicinity of the detector. The detector’s microcontroller processes the two signals. The temperature signal processing extracts only rate of rise information for combination with the optical signal. The detector will not respond to a slow temperature increase – even if the temperature reaches a high level. A large sudden change in temperature can, however, cause an alarm without the presence of smoke, if sustained for 20 seconds. The processing algorithms in the multisensor incorporate drift compensation. The control panel must not have a drift compensation algorithm enabled. The sensitivity of the detector is considered the optimum for most general applications since it offers good response to both smouldering and flaming fires.Note: In situ testing of the multisensor should be carried out as for smoke detectors.

Accepts all Context Plus Xpert card stlyle smoke and heat detectors. It is a zero insertion force base with dual finger receptacles of stainless steel into which the detector terminals slide. Cable connections of up to 2.5mm diameter are made via captive cable clamps. Includes four double terminals (L1 = – line IN and OUT; L2 = + line IN and OUT; +R = remote LED positive supply; -R = remote LED negative supply) and one isolated single terminal that can be used to provide continuity of an earth or shield. XPERT cards, are supplied with all bases. Consult the coding guide to determine which pips are to be removed. Pre-printed and pre-punched address cards that save time and increase accuracy during commissioning are available in sets (part number: 45682-127). The base has a ‘one way only’ fit and detectors can be locked into the base by a grub screw with the aid of a 1.5mm hexagonal driver. 20DIsolating Base, XPERT style, 45681-321IMC or 45681-284IMC The Context Plus XP95 20D isolating base senses and isolates short circuit faults on loops and spurs. The base is loop powered, polarity sensitive and accepts the XPERT card to set the associated device address. In short circuit conditions, the integral yellow LED is illuminated. The detector associated with the base remains active under short circuit conditions. Power and signals to the affected section are restored automatically when the fault is cleared. Under normal operating conditions, a low impedance is present between the – IN and – OUT terminals of the base, so that power and signals pass to the next base in the line. If a short circuit or abnormally low impedance occurs, the fall in voltage is sensed and the base isolates the negative supply in the direction of the fault In applications where it is not necessary to use an isolating base for each detector, up to twenty devices (detectors and interfaces) may be installed between isolating bases, provided that their total switch-on surge current does not exceed 20mA. Circuits may include spurs, which should be connected between the spare –OUT terminal and the base L1 terminal. Spurs connected in this way appear directly across the loop on the output side of the isolating base. Short-circuit faults on the spur therefore short circuit the loop and vice versa. The effect of such short circuits must be taken into account in the system design and may require the use of extra isolating bases.

We are offering manual call point with isolator at very market leading prices company. The Context Plus XP95 Manual Call Point is intended for indoor applications and incorporates a short circuit isolator which will ensure its operation in the event of a short circuit fault on the loop. The Call Point is surface mountable and has an easily resettable element rather than a break glass. It also features a unique ‘Plug and Play’ installation concept designed specifically to reduce installation time. The call point utilises a terminal block, where all installation cabling is terminated. Its address is set at the commissioning stage by means of a seven-segment DIL switch. A single bi-coloured alarm LED is provided which is controlled independently of the call point by the control panel. The LED is illuminated red when the call point has been activated and amber/yellow to indicate a short circuit. Once activated, the Call Point can be reset by inserting the test key into the bottom of the unit until the key clicks into position, next remove the test key and push the front cover up until it clicks home.

The address of the DSA Context Plus detectors is set using the DIL switch located on the underside of the device. All segments are set to 0 (ON) or 1 (OFF), using a small screwdriver or similar tool. The address should be written on the label and the rear of the detector sealed.

We are offering best Ionization Smoke Detector The Context Plus XP95 ionisation smoke detector has a moulded selfextinguishing white polycarbonate case with wind resistant smoke inlets. Stainless steel wiper contacts connect the detector to the terminals in the mounting base. Inside the detector case is a printed circuit board that has the ionisation chamber mounted on one side and the address capture, signal processing and communications electronics on the other. The ionisation chamber system is an inner reference chamber contained inside an outer smoke chamber. The outer smoke chamber has smoke inlet apertures that are fitted with an insect resistant mesh. The radioactive source holder and the outer smoke chamber are the positive and negative electrodes respectively. An Americium 241 radioactive source mounted within the inner reference chamber irradiates the air in both chambers to produce positive and negative ions. On applying a voltage across these electrodes an electric field is formed. The ions are attracted to the electrode of the opposite sign, some ions collide and recombine, but the net result is that a small electric current flows between the electrodes. At the junction between the reference and smoke chambers is the sensing electrode that is used to convert variations in the chamber currents into a voltage. When smoke particles enter the ionisation chamber, ions become attached to them with the result that the current flowing through the chamber decreases. This effect is greater in the smoke chamber than in the reference chamber and the imbalance causes the sensing electrode to go more positive.  

The Context Plus XP95 input/output unit provides two voltage-free, single pole, change-over relay outputs, asingle monitored switch input and an unmonitored, non-polarised opto-coupled input. FEATURES Compliant with EN54-17 & 18 (2005), the Input/Output Unit supervises one or more normally-open switches connected to a single pair of cables. It is set to return an analogue value of 4 in the event of an open or short-circuit fault and 16 during normal operation. The status of the inputs is reported by means of two input bits. The change-over contacts are operated by an output bit. The Input/Output unit is fitted with a bi-directional short-circuit isolator and will be unaffected by loop short-circuits on either loop input or output. ELECTRICAL CONSIDERATIONS The unit operates at 17-28V DC with protocol voltage pulses of 5-9V. No electrical supply greater than 50V AC rms or 75V DC should be connected to any terminal. Designed for indoor use only it includes four LEDs, two red and two yellow, which are visible through the front cover of the enclosure. One red LED is illuminated to indicate that the relay is set. The second red LED is illuminated to indicate that the switch input is closed. One yellow LED is illuminated whenever a fault condition (open or short circuit) has been detected. The other LED is illuminated whenever the built-in isolator has sensed a short-circuit loop fault. The enclosure is moulded from white self-extinguishing polycarbonate.
