Relay outputs
The alarm monitor has 3 output relays; all of them can be activated by any of the 8 alarm inputs. The relays
can work as de-energized or energized, when the power is on the alarm monitor. The alarm monitor is
delivered with all output relays operating in normally de-energized mode.
This section contains information about the 2 principles and how and when to use them.
This section only contains information about the relay outputs (terminal 27 - 35). The examples in this
section are based on the siren relay, but all of the 3 output relays can be used individually with the same
functionality.
Normally de-energized
Figure 4 shows the default connection of the output terminals on the alarm monitor.
The alarm monitor is delivered with all output relays operating in normally de-energized mode. This means
that the relay stays in the same position, whether the power is on or off. When an incoming alarm activates
the relay, the position will change from terminal 33 to 35 (siren relay).
The output relay is supplied from same source as the unit. The siren is connected to the output relay.
Terminal 26 and the siren are connected to ÷ (negative supply).
NOTE:
Regarding load capacity for the output relays, please refer to the section Load capacity on page 9 in this
manual.
