Smoke Detectors save lives

All night, when you and your family are asleep, fires are at their most dangerous. Toxic smoke, given off when substances such as plastics burn, does not wake you up; it makes sleepers unconscious. Smoke detectors therefore save lives. The smoke detector is a quality product designed for private households. It detects the smoke generated by smouldering fires and gives an alarm. A loud pulsating tone (approx. 85 dBA) wakes you up and can therefore save your life and the lives of your family.

Product Features

Photoelectric principle: reliable, robust, highly sensitive reaction to smoke
Battery operation: not dependent on mains power
Red LED flashes briefly about every 40....50 seconds; the detector has performed a self-test and is
in good working order.
Battery low-power monitor: the smoke detector indicates that the battery voltage is growing weaker by emitting short beeps at intervals of 40...50 seconds.
Loud pulsating warning tone if smoke detected: highly effective (approx. 85 dBA)
System operation (ohly when type Relay/Networking): up to 40 smoke detectors can be linked
together; if one of them detects a fire, the alarm is given by all detectors in the circuit.
Reverse polarity protection: the detector is not damaged if the battery is installed with the wrong polarity.

Choice of location

The smoke detector must be fixed to the ceiling as near to the centre of the room as possible. One detector can monitor a room with a maxium floor area of 60 m hallways and narrow corridors (up to 3 m wide) the detector monitors distances up to 7,5 m in each direction. A gap of at least 0,5 m must be maintained from walls and fixtures. You should therefore install (see Fig. 1):
as an absolute necessity one smoke detector in the hallway (to monitor the escape route) between living and sleeping areas
for optimum protection one detector in every living room and every bedroom
in multistorey buildings at least one detector on each landing
in converted lofts one detector above the staircase
Installation on the ceilings of boat cabins or caravans is also possible. When travelling, simply take smoke detector with you into your hotel room.

Installation Instructions

Unsuitable Locations

Never install the smoke detector
near to air ducting and strong drafts
directly in the apex of pitched roofs (a minimum distance of 30 cm from the apex must be
maintained)
in rooms where there is a lot of steam, dust or smoke under normal conditions(e.g. workshops, kitchens, bathrooms, laundry rooms, etc.)
in rooms where the temperature rises above + 40°C or falls below + 5°C.

Installation and Commissioning
Remove the smoke detector from ist base by turning it anticlockwise.
Screw the base to the ceiling using the fixing materials provided (see Fig. 2 for dimensions).
Attach the 9 V rectangular battery to the connector.
Insert the smoke detector into the base and turn it gently clockwise until it clicks into place.

Linking Several Smoke Detectors

With the type Relay/Networking smoke detector up to 40 devices can be linked together in one network. To do this, first remove the plastic protection from the terminal strips. The connection from detector to detector is by means of a two-core cable (telephone cable), the terminals 3 and 4 (green) being used as whown in Fig. 3. An external alarm device can be connected to the volt-free contacts via terminals 1 and 2 (orange). If an inductive load (e.g. a klexon or a relay of an unknown design) is connected, a free-wheeling diode (type 1N4007) must be included in the circuit, so that the smoke detector is not damaged by inductive voltages.
