Relay Wiring
Two Form-C contact relays are provided for controlling door
lock mechanisms. The relay contacts are rated at 2A @ 30V

pole (C), a Normally Open pole (NO), and a Normally
Closed pole (NC).
When momentarily delivering power to unlock the locking
hardware (fail secure), the Normally Open and Common
poles are used. When momentarily removing power to
unlock the locking hardware (fail safe), the Normally Closed
and Common poles are used. Check with local building
codes for proper egress door installation.
Door lock mechanisms can generate EMF feedback to the
relay circuit 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.
From the Auxiliary output, the ADC-ACC1-17 can provide
12V DC power for external devices, provided 650 mA is not
