Description

Heat Detection. The Series 60 heat detectors are resettable and operate by using a matched pair of thermistors to sense heat. One thermistor is exposed to the ambient temperature, the other is sealed. During normal conditions the two thermistors register similar temperatures, but, on the development a fire, the temperature recorded by the exposed thermistor will increase rapidly, resulting in imbalance of the thermistors and causing the detector to change to the alarm state. Rate of rise detectors are designed to detect a fire as the temperature increases, but they also have a fixed upper limit at which the detector will go into alarm if the rate of temperature increase has been too slow to trigger the detection earlier. Fixed heat detectors only change to the alarm state at a preset temperature.

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 a reduction of the current flow in the outer chamber and hence an increase in the 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.

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 fi re entering the labyrinth the light pulse from the LED will be scattered and hence registered by the 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 in quiescent state but produces red light in alarm. The optical detectors are easy to disassemble and clean without the necessity of returning them to the factory.
