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.
