4.4 installing several detectors in a network

It is possible to interconnect up to 40 detectors to enable alarm activation over the whole

range of smoke and ﬁre detectors installed in the home.

iMPoRtAnt: 155-21X heat detectors can only be connected with the same type of

detectors: e.g. a 155-21X can be connected with 155-21X heat detectors or 151-21X smoke

detectors.

You can therefore be sure of being warned if smoke is detected in a room far away from the

room in which you are in.

1. Once the detector's base has been ﬁxed in place (see Fixing the detector in place),

unclip the connector block.

2. Then wire as follows:

For 15 mm

wires, the overall network length must not exceed 400 m.

3. Clip the connector block back in place.

4. Lock the detector onto the base (see Fixing the detector in place).
