³
For the detectors’ power supply connection, we recommend using a 2-wire cable with
suitable section according to the distance and number of detectors.
³
Once the installation has been completed, verify that each detector reaches at least
12 Vdc.
5.8 Connection to relay board (optional)
During configuration of SMART S-IS detector it’s possible to associate alarm thresholds and
fault signal to the relay board.
Relay 1 is associated to Fault and Watch-dog. The remaining two are to be associated to two
outputs of the three pre-set alarm thresholds. Default relays associations are: threshold 2-re-
lay 2; threshold 3-relay 3.
Relays are not-memorised and they are not time-limited. The user cannot silence the alarm
manually, it will silence automatically when the its cause won’t be present anymore.
