“Auxiliary” operating mode
NOTES
- Modes 5 and 6 give the same operating results of modes 3 and 4. Their dierence is that the relay is
normally not excited. This enables an opposite behaviour in case of tampering (cutting of the wire
or BUS short circuit). In fact in mode 3 and 4 a tampering excites the device (modes indicated in
the case of actuation of alarms such as the siren, the telephone communicator, etc.); however, in
mode 5 and 6 the same tampering does not cause any actuation (modes indicated in case of safety
actuations such as electrical door locks etc.). The selection of the appropriate mode ensures total
system safety.
- The “S” key of the 3 module ush-mounted central unit or the disabling of the central unit with display,
which main function is that of silencing the sirens during a technical alarm, disables the relay if this has
been activated by the technical alarm interface congured in mode “0” or “4” (technical alarm).
- In all modes there is an auxiliary activation also in case of pre-alarm (IR detector and contact interface
with AUX congurators). Attention must therefore be paid when using the relay actuator (in modes with
memory or with sensitivity to any auxiliary channel) to avoid unwanted activations.
