NOTE
The AO-4 modules must be connected to the RS-485 Master Port and addressed correctly in
the range of A1h-A8h.
An AO-4 module connected properly to the controller will have a flashing DATA COMM LED to indicate
a valid communication status and will provide a continuous output mA reading that corresponds directly to
the sensor attached. If the controller does not detect an AO-4 module, the blue LED (Fault) will start
flashing and COMM ERROR will be displayed on the AO-4 group page.
3.5 Alarm Relay Outputs (RL-4)
There are four (4) Form C Single Pole Double Throw (SPDT), 5 Amp relays in each Model RL-4 module.
Each relay in the module is assigned specifically to one alarm. Relay 1 is assigned to Alarm 1, relay 2 is
assign to Alarm 2, relay 3 is assigned to Alarm 3, and relay 4 is assigned to Fault. These can be used to
control (fire) annunciating devices or as signal inputs to other control devices. Connections to the relay
contacts of the RL-4 module are shown in Figure 33 and are labeled C (Common), NO (Normally Open)
and NC (Normally Closed). Note that the 5 Amp rating of the relay contact should not be exceeded. RL-4
modules are installed on the DIN rail of the controller.
NOTE
There are four Form C, Single Pole Double Throw (SPDT), 5 Amp relay contacts in each
RL-4 module. Each relay in the module is assigned to one alarm as follows:
 Relay 1 is assigned to Alarm 1
 Relay 2 is assign to Alarm 2
 Relay 3 is assigned to Alarm 3
Relay 4 is assigned to Fault

NOTE
The current ratings of the relay contacts, 5A @ 30VDC, 5A @ 250VAC and 5Amp rating
should not be exceeded. Wire attached to the RL4 terminals must be safety approved and
rated for at least 5A.
