Apollo Series 65 Optical Smoke Detector with Flashing LED and Magnetic Test Switch 55000-315APO

Apollo Series 65 Optical Smoke Detector with Flashing LED and Magnetic Test Switch 55000-315APO

Apollo Series 65 Optical Smoke Detector with Flashing LED and Magnetic Test Switch 55000-315APOThe Series 65 Optical Smoke Detector incorporates a pulsing LED located within the housing of the detector. The external detector moulding is identical to that of the ionisation detector and has an indicator LED which is clear in quiescent state but produces a red light in alarm.OperationThe Series 65 Optical Smoke Detector has a moulded self-extinguishing white polycarbonate case with wind resistant smoke inlets. Nickel-plated stainless-steel wiper contacts connect the detector to the base. Inside the case a printed circuit board has the optical system mounted on one side and the signal processing electronics on the other. The sensing chamber is a black moulding configured as a labyrinth which prevents penetration of ambient light. The labyrinth has a fine gauze insect-resistant cover. The chamber houses an infrared light emitting diode LED and a photo-diode which has an integral visible-light filter as extra protection against ambient light. Every three seconds the LED emits a burst of collimated light modulated at 4kHz. In clear air light from the LED does not fall directly on the diode because the LED is positioned at an obtuse angle to the diode. When smoke enters the chamber a fraction of the collimated light is scattered onto the photo-diode. If the resulting signal from the photo-diode is above a pre-set threshold the LED emits two more bursts of light this time at two-second intervals. If light is scattered onto the photo-diode by both these pulses due to the presence of smoke the detector signals an alarm state by switching the alarm latch on increasing the current drawn from the supply from about 40A to a maximum of 75mA. This fall in the impedance of the detector is recognised by the control panel as an alarm signal. The alarm current also illuminates the detector integral LED. A remote indicator connected between the L1 IN terminal and the R terminal will have a voltage equal to the supply voltage less 1 volt across it and so will illuminate. To ensure correct operation of the detector the control panel must be arranged to supply a maximum of 33 Volts dc and a minimum of 9 Volts dc in normal operation. The supply may fall to 6 Volts dc in alarm conditions if a supply current of at least 10mA is available at this voltage. To ensure effective illumination of the integral LED and any remote indicator the supply to the detector should exceed 12 Volts. To restore the detector to quiescent condition it is necessary to expel any smoke and interrupt the electrical supply to the detector for a minimum of one second.Key FeaturesResponds well to slow-burning smouldering firesWell-suited to bedrooms and escape routesUnaffected by wind or atmospheric pressureFlashing LED and magnet operated test switch option

Apollo Orbis CR Heat Detector with Flashing LED ORB-HT-11017-APO

Apollo Orbis CR Heat Detector with Flashing LED ORB-HT-11017-APO

Apollo Orbis CR Heat Detector with Flashing LED ORB-HT-11017-APOThe Orbis Heat Detector monitors temperature by using a single thermistor which provides a voltage output proportional to the external air temperature.OperationOrbis heat detectors have an open-web casing which allows air to flow freely across a thermistor which measures the air temperature every 2 seconds. A microprocessor stores the temperatures and compares them with pre-set values to determine whether a fixed upper limitthe alarm levelhas been reached. In the case of rate-of-rise detectors the microprocessor uses algorithms to determine how fast the temperature is increasing. Static heat detectors respond only when a fixed temperature has been reached. Rate-of-rise detectors also have a fixed upper limit but they also measure the rate of increase in temperature. A fire might thus be detected at an earlier stage than with a static detector so that a rate-of-rise detector is to be preferred to a static heat detector unless sharp increases of heat are part of the normal environment in the area protected by the heat detector.

Apollo Marine DIN-Rail Zone Monitor 55000-773MARThe Marine DINRail Zone Monitor powers and controls the operation of a zone of up to 20 conventional fire detectors from a loop of XP95 addressable detectors and ancillary devices.OperationThis unit needs to be installed in a suitable enclosure and secured using end stops part no 27447-528 or equivalent. The Marine DINRail zone monitor is factory pre-set to return an analogue value of 16 when all detectors on the zone are in the quiescent state and 64 when a detector changes to the alarm state.The unit latches in the alarm state. A 5.1K end-of-line resistor is used to monitor 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 50F fitted at the unit wiring terminals. In either case an analogue value of 4 is transmitted during open or short-circuit faults.The Marine DINRail zone monitor is fitted with a bi-directional short-circuit isolator and will be unaffected by loop short-circuits on either loop input or output.Key FeaturesLoop-poweredVisible short-circuitLED Built in isolator

Apollo XP95 DIN-RAIL Zone Monitor with Isolator - 55000-812APO

Apollo XP95 DIN-RAIL Zone Monitor with Isolator - 55000-812APOThe DIN-Rail Zone Monitor with Isolator powers and controls a zone of up to 20 Apollo Series 65 or Orbis fire detectors in a Discovery or XP95 loop.OperationThe DINRail Zone Monitor is factory preset to return an analogue value of 16 when all detectors on the zone are in the quiescent state and 64 when a detector changes to the alarm state. The unit latches in the alarm state. A 5.1k end-of-line resistor is used to monitor 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 50uF fitted at the unit wiring terminals. In either case an analogue value of 4 is transmitted during open or short-circuit faults.The DINRail Zone Monitor is fitted with a bi-directional short-circuit isolator and will be unaffected by loop short-circuits on either loop input or output. For IS applications use DIN-Rail IS Zone Monitor part number 55000-798.Key FeaturesLoop-poweredVisible short-circuit and alarmLEDs Built-in Isolator
