It operates on the proven light scatter principle. Inside the sensing chamber, a light source and a light sensor are arranged so that light normally does not fall on the sensor. It is only when airborne particles enter the chamber that light is scattered onto the sensor (Tyndall effect) to produce the electrical signal. This design means that no radioactive source is required. Smoke alarms and Alive signal are transmitted via the Dupline® bus. Besides alarms, the built-in LED also shows the operational status of the device. A test button allows a manual check of the alarm function, while simultaneously an alarm is given via the Dupline® bus. Optional use of the smoke detector as alarm device for other detectors such as gas, water and burglary via Dupline®. Input Specifications Detector Response level Optical (Tyndall effect) According to EN 12239 (95) General Specifications Channel programming Channel assignment I/O number 1 Ordering Key Type: Dupline Type Type Selection Ordering no. Supply Current consumption typ. Battery current consumption Supply voltage Current consumption when alarm is active 7.5 mA I/O number 4 Monitoring of sensor sensitivity. The signal is active if the sensor becomes dirty. I/O number 5 Forced alarm. The smoke sensor can be used as an alarm device for e.g. water, gas and burglar alarms. If the Dupline® connection is interrupted, the smoke sensor will still work, but as a normal individual smoke detector. Red LED (short flash once every 42 sec. (alive signal): The smoke detector is OK. Short flash every 0.5 sec.: Alarm. Red flash (42 sec.) and simultaneous beep = Low battery voltage. Red flash (42 sec.) and asynchronous beep = Dirty Indication Monitoring of sensor (tamper/presence). The signal is always active if OK, otherwise inactive.

Ø 100 x 51 mm ABS White > 85 dB(A) / 3 m (10 ft) IEC 6LR 61 2 years Acoustic and optical G202055 G202055 · Hallways and narrow corridors may have a width of up to 3 m (10 ft) and a length of up to 15 m (50 ft) · The mounting location must be as close as possible to the centre of the room · A minimum distance of 0.5 m (1,5 ft) must be maintained from walls and furniture · Directly in the apex of pitched roofs (a minimum distance of 30 cm (1 ft) from the apex must be maintained) · In rooms which are usually very steam-, dust- or smoke-filled (for example in workshops, bathrooms and laundry rooms) all other connected alarms. The smoke alarms are connected in parallel using a 2wire cable. The G8920 G8920 5517 709 must NOT be mounted in the following locations: · Near ventilation ducts or strong draughts Connection of multiple smoke alarms It is possible to interconnect several smoke alarms so that the alarm signal from one alarm is transmitted to IP 43 0 to 50°C (+32° to +122°F) -5 to +85°C (+23 to +185°F) ISO 12239 Screw terminals Wire diameter: 0.4-1.5 mm See wiring diagrams Notes on application To achieve minimum protection, one G8920 G8920 5517 709 should be installed in front of each sleeping area or each floor. Higher protection will be achieved if one smoke detector is present in every room (except for the kitchen and the bath - here, false alarms may occur due to steam development). When using the G8920 G8920 5517 709, the following issues must be observed: · Rooms may have a floor area of up to 60 m2 and a height of up to 6 m Note: Make sure that the total power consumption does not exceed the channel generator's output when interconnecting the smoke alarms. Use a backup battery to avoid voltage drop in the Dupline Bus when using interconnection. Wiring Layout and Description Switch = 0 Normal position. If the battery is removed, the smoke alarm indicates ­ Low bat. Battery O I UP Switch Switch = 1 Bypass of "Low bat" indication. The smoke signal device does not indicate "Low bat" alarm if the battery is removed. Programming The I/O addresses and the passive/active alarm may be programmed by means of GAP 1605, using the GAPTHP-CAB cable. If the Dupline® signal fails, the output will go to the predefined fault polarity.
