Relay Circuit Wiring
Two (2) relays are provided for controlling door lock mechanisms or alarm signaling. The relay contacts are
rated at 2A @ 30 VDC, dry contact configuration. Each relay has a Common pole (C), a Normally Open
pole (NO) and a Normally Closed pole (NC). When you are controlling the delivery of power to the door
strike, the Normally Open and Common poles are used. When you are momentarily removing power to
unlock the door, as with a mag lock, the Normally Closed and Common poles are used. Check with local
building codes for proper egress door installation.
Inductive door locking devices may induce relay contact arcing as the contact opens that can cause damage
and premature failure of the relay. For this reason, it is recommended that either a diode or MOV (metal
oxide varistor) be used to protect the relay. Wire should be of sufficient gauge to avoid voltage loss.
Note:
Do not program the relays to activate (switched ON state) by default at power up.
