Function
R1
Programmable Alarm Relay
R2
Programmable Alarm Relay
R3 Programmable Alarm Relay
R4 Programmable Alarm Relay
Failure :(Fault) Non-programmable common relay, energized, activated upon the presence
of a failure in the MX32v2 (detector and/or module, system failure, etc.).
The acknowledgement of this relay is automatic.
The dry relay contacts (nominal resistive load of 5A at 250Vac or 30Vdc) are identified as R1,
R2, R3, R4 (Figure 27, tag A) and Fault (Figure 27, tag B).
Figure 27: Internal alarm relays (A) and fault relay (B) terminals
The relay contacts are represented when no power applies to the MX32v2 . The
relays are programmed via the COM 32 application and can be set as energized
or de-energized.
6.1.8 Remote Acknowledgement Connector If necessary, connect the
ACQUIT (dry contact relay, NC) terminal to a remote acknowledgement system.
