Reliable operation can only be guaranteed if the instructions are followed correctly. Please check the installation location carefully in advance in case there are any electrical installations behind the wall or above the ceiling! In case of alarm a very loud sound is emitted. Do not switch the unit on in close proximity to anybodies ears! Keep away from children! This smoke detector is a photo electric sensor with integrated relays to connect to any alarm control system such as the RMS. When smoke is detected a loud siren is sounded and the relay is activated. Smoke detection works using scattered light technology which is highly sensitive to any fire especially smouldering fire. The integrated heat sensor activates the alarm at approximately 70~85°C. An automatic self test is performed regularly and any malfunction is shown by the integrated LED. Supplied Contents Smoke detector, 2 screws, mounting plate, ~4m cable, this manual Technical Data Operating voltage: 12 V DC or AC +/-15% Typical current: 2mA, Alarm current approx. 25mA Operating temperature: 0°C ~ +55°C Humidity: 25% ~ 75% relative humidity, non condensing, for indoor use Smoke sensor: scattered light principle Sensitivity: m= 0,05…0,07dB/m (EN 54-7) Heat sensor alarm 70°C~85°C Alarm siren ~ 85dB(A) / 3m Life time: 10 years maximum Relay: max. 1A@120VAC, max. 2A@24VDC Conformity: EN54-7 and prEN ISO 12239 Cable: ~ 4m Weight: 0.1kg Dimensions: . 12 x 4cm Placement The Smoke sensor should be mounted on the ceiling, if possible, in the centre of the ceiling. A minimum distance of 60cm to any wall or other equipment should be kept. In rooms with non horizontal ceilings the sensor should be placed approximately 1m off the highest point. In long corridors or rooms the smoke sensor should not be more than 4m away from any wall and should not be spaced more than 8m apart . As a rule of thumb: One smoke detector can cover a room of 50m. approx. The following locations are not suitable and should not be used: Near a wall, window, door, heating or ventilation device, in stair cases or in any place with constant air flow. Any area where the temperature often falls below 4°C or increases over +40°C In any area with high relative humidity, for instance bathrooms In small or poorly ventilated garages, kitchens or similar, otherwise false alarms may be caused by exhaust gases and steam Any place where the self test LED button cannot be reached Close to fluorescent lamps (keep a minimum distance of 50cm!) or close to cables or any area with a high degree of electrical interference In any rooms or areas with a high degree of dust or dirt, otherwise false alarms can be caused (i.e. workshops, barns) Installation 1. This smoke detector should only be powered from an appropriate regulated power supply. Follow your local installation guidelines and legal instructions! Protect the smoke detector from dirt and dust! 2. Drill a hole for the cable through the back of the detector. Guide the cable through the hole and fix it to the mounting plate or ceiling. Connect the cable to your alarm system / the RMS as follows: The blue contact strip can be pulled off the PCB for easy connection of the cables. U, U Power supply (11 – 15 Volt AC or DC) REL, REL Output relay contacts The jumper contacts (K4) sets the detector function as NO (normally open contact) or NC (normally closed contact). The jumper contacts (K5) set the contact function of the relay: K5=ON -> the alarm and the relay are activated for a short time until the supply voltage is interrupted. This helps to localize the detector that has caused the alarm. K5=OFF -> the alarm and relay is self reset as soon as the smoke density goes back to normal. 3. Finally, put the contact strip back on to the PCB. Put the cover back into its place and close it firmly so that both latches are engaged. Switch on the supply voltage. Now, the detector should give one beep to indicate its operation state. Next, hold the LED test button down until a loud pulsating warning tone is emitted and the relay is activated. Operation Under normal operation, every 40 seconds a self test is performed. This is indicated by a short LED flash. As soon as the sensor detects smoke the alarm is activated (siren and relays). If K5 is set to OFF the alarm is reset as soon as the smoke density goes below the alarm level – the detector is active again. To test the detector manually, hold down the test LED button until the alarm is sounded. False Alarms When an alarm is activated, check carefully for hidden fires. To reset the alarm, ventilate the room for a while and then switch off the supply voltage (if K5 is set ON) for a short time. Use a vacuum cleaner to clean the detector. Maintenance Use a dust or vacuum cleaner to clean the detector every 6 months. The cover can be cleaned with a damp cloth. Do not use any strong solvents. Do not paint the detector.
