SERIES 65 IONISATION SMOKE DETECTOR

The sensing part of the detector consists of two chambers - an open, outer chamber and a semi-sealed reference chamber within. Mounted in the reference chamber is a low activity radioactive foil of Americium 241 which enables current to flow between the inner and outer chambers when the detector is powered up. As smoke enters the detector, it causes reduction of the current flow in the outer chamber and hence an increase in voltage measured at the junction between the two chambers. The voltage increase is monitored by the electronic circuitry which triggers the detector into the alarm state at a preset threshold. An externally visible LED will light up when the detector changes to alarm state.

SERIES 65 OPTICAL SMOKE DETECTOR

Optical smoke detectors incorporate a pulsing LED located in a labyrinth within the housing of the detector. The labyrinth is designed to exclude light from any external source. At an angle to the LED is a photo-diode which normally does not register the column of light emitted by the LED. In the event of smoke from a fire entering the labyrinth the light pules from the LED will be scattered and hence registered by photo-diode. If the photo diode "sees" smoke on the two following pulses, the detector changes to the alarm state when the indicator LED will light up. The detector housing is identical to that of the ionisation smoke detector. It is distinguished from this type by having an indicator LED which is clear quiescent state but produces red light in alarm.

SERIES 65 HEAT DETECTOR

The series 65 heat detectors are reset table and operate by suing a matched pair of thermistors to sense heat.

SERIES 65A COMBINED HEAT AND SMOKE DETECTOR

Series 65A are the latest type of detectors offering heat and optical smoke detection from the single unit.

The design and feature of Models from the new World Series of Call Points benefit from the experience gained during nearly quarter of a century spent specialising in Manual Call Points of the Break Glass Type.

The smoke/heat detectors and manual call stations are programmed through the control panel in such a way that each component is given a number and the exact location. Like optical smoke detectors No. 7, location generator room. Which means when the fire is detected by detector No. 7, the control panel will show the detector number and location on its display and a print out by the printer, which makes the fire staff to go exactly at the right place rather to wasting time in searching the whole zone, thus minimising the response time, and we all know, in a fire situation even seconds count. The complete system can be networked by using specially designed software and computers for sophisticated monitoring. Similar faults are also identified by exact location.

Analogue Addressable Loop Device

As smoke enters the outer chamber the flow drops and voltage increases. The voltage is measured and an analogue signal is converted to digital for transmission to control equipment. Pre-alarm or fire alarm is instigated by the microprocessor when smoke density increases to pre-set-levels.

When smoke enters the chamber it scatters light onto the photo-diode, increasing the signal transmitted to control equipment. The clear LED emits red.

The XP95 temperature monitor has a low air-flow resistant case for good contact between sensing thermistor and surrounding air. Temperature is measured by a single themistor network which gives a voltage output proportional to the external air temperature. The signal is processed and transmitted to control equipment.

When operated the manual call point interrupts the polling cycle and can report its address in under 0.2 seconds.
