4.3 Alarm Relay Wiring (J1, J5, and J6)
To connect the control wires to the three relay terminals on the relay board, wire the unit
to the connectors shown in Figure 2-4. The low alarm relay is activated when the low alarm
threshold is met. This is a non-latching, Normally Open (NO) contact. The high alarm relay is
activated when the high alarm threshold is met. This is a non-latching, Normally Open (NO)
contact. The fault alarm relay is activated upon power-up of the . When the fault condition
is met, the circuit opens. This is an Electronically closed (NC) contact. See Figure 4-1 for relay
wiring.
NOTE: It is recommended that on-board relays should not be used to drive loads directly. On-
board relays should be used to drive a secondary, higher-power relay which is connected to the
control device (e.g., strobe, siren, exhaust fan, etc.).
