Open-collector transistor
The collector on the control panel’s
output must be connected to the alarm
input’s signal side.
This connection can keep the control panel
galvanically isolated from the alarm transmitter if
the transistor is, for example, the output from an
optically-coupled isolator.
An order must be placed to change the service or the control of the alarm. Contact AddSecure
for additional information about orders and changes to the alarm transmitter. Local
programming is not necessary.
6.5
Relays (outputs)
6.5.1
Error indication
Relay 3 (FAULT) is used to signal errors when the alarm transmitter is used for fire alarms.
Connection: Connect relay 3 with pin 11 (normally open) and pin 9 (common) to the alarm
panel at the appropriate input so that the alarm panel can detect a short circuit/open circuit
on the connection.
Status: Ok.
The relay is closed when the alarm transmitter is fully functional.
Status: Error.
The relay opens in the event of an error or when the alarm transmitter is not fully
functional; for example, if there is a restart or when the alarm cannot be sent or when
no acknowledgment is received from the alarm receiver.
6.5.2
Indication of ongoing alarm
Relay 4 (ACK) is used when the alarm transmitter is configured for fire alarms and to indicate
that the alarm transmitter has ongoing alarms.
