Apollo XP95 Manual Call Point with Isolator - 55100-908APO

Apollo XP95 Manual Call Point with Isolator - 55100-908APOThe XP95 range of analogue addressable fire detectors uses tried and trusted technology to give the best performance and has unique features that benefit the installer and the end user. It is suitable for medium-to-large applications with simple installation requirements. As it operates using digital communication XP95 has a high immunity from corruption and is therefore often preferred in a large system where life safety is critical. XP95 products are frequently used in commercial industrial financial government ITtelecoms and healthcare applications.The new Apollo XP95 EN54-112001 compliant Manual Call Point MCP is based on the KAC conventional MCP range. It is electronically and mechanically backward compatible with previous Apollo call points based on KACs World Series product. The address of each call point is set at the commissioning stage by means of a seven-segment DIL switch.A single bi-coloured alarm LED is provided on the call point. This LED is controlled independently of the call point by the control panel. The red LED is lit when the call point has been activated. An amberyellow LED indicates a fault. Call points can be remotely tested from the panel by transmission of a single bit in the communications protocol. Call points respond by providing a value of 64 which corresponds to the alarm value.The choice of detector from the XP95 range follows well established principles of system design. The optimum detector type will depend on the type of fire riskfire load and the type of environment in which the detector is sited.Key FeaturesA seven-segment DIL switch enables the addressing of each call point at commissioning stageWhen operated the manual call point interrupts the polling cycle for a fast responseBi-coloured LEDs indicate isolate and normal conditions

Apollo XP95 Beacon Base with Isolator - 45681-333APO

Apollo XP95 Beacon Base with Isolator - 45681-333APOThe Visual Indicator Base is a loop-powered visual indicator combined with a standard Intelligent Mounting Base. It is used to signal a fire alarm in enclosed areas. The visual indicator base can be used with either a detector fitted or with a cap as a stand-alone alarm device. The base is loop powered so needs no external power supply. It operates at 1728V DC and is polarity-sensitive.Device AddressingThe Base responds to its own individual address set with a DIL switch. It also responds to a group address set by means of a 4-segment DIL switch and to a synchronisation address which is embedded in the unit. Addresses 1 to 111 are used exclusively for individual addresses addresses 112 to 126 are used for group addressing while the synchronisation address to which all units respond is 0. Any Beacon Base on a loop may be freely assigned to a group. The address for any group must be chosen from the range 112126.Addresses 112126 may be used as individual addresses but only if the 4-segment DIL switch is not used ie group addressing is disabled. If the 4-segment DIL switch were set to any number other than the default 127 a pre-set analogue value of 4 would be transmitted to indicate a fault. The Base is normally polled by its individual address. It responds as described below. It is recommended that the synchronisation address 0 be sent by the control panel at regular intervals to align the internal clock of all sounders. The result is that the beacons are synchronised with each other when activated.Key FeaturesVisual indicator flash rate of once per secondSynchronisation of visual indicator flashIndividual and group addressingUnique visual indicator self-testLoop-poweredBuilt-in Isolator

Apollo 45681-330APO Intelligent Sounder Visual Indicator Base with Isolator

Apollo 45681-330APO Intelligent Sounder Visual Indicator Base with IsolatorThe low volume range is useful in areas such as hospitals where a fire alert is initially intended to warn staff only. The sounder is set to the high range for general use. Synchronisation of tones ensures the integrity of the signaltones from different sounders do not merge into one signal that could be mistaken for a different tone. Group addressing is a simple method of alerting an entire area or group of rooms without delay.For systems requiring isolators at every point the built-in isolator saves installation time and cost. The acoustic self-test means that the sounder listens to itself when it is switched on. If no sound is detected a fault signal is transmitted when the sounder is polled.The beacon self-test is achieved by means of an LED monitoring circuit. If the LEDs do not draw current when the sounder beacon base has been switched on a fault signal is transmitted when the device is next polled.Key FeaturesTwo volume ranges 55-75dBA and 75-91dBAVisual indicator flash rate of once per secondSynchronisation of alert and evacuate tonesSynchronisation of visual indicator flashIndividual and group addressingUnique acoustic and visual indicator self-testBuilt-in Isolator

Apollo Series 65 Optical Smoke Detector with Flashing LED 55000-316APO

Apollo Series 65 Optical Smoke Detector with Flashing LED 55000-316APOThe 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
