Input Wiring
There are 8 inputs that are typically used to monitor door
position or request to exit devices. Input circuits can be
configured as Unsupervised (2 states); reporting as open or
closed contact, or Supervised (6 states); reporting as open
or closed contact, open circuit, shorted circuit, grounded
circuit *, or foreign voltage*.
A supervised input circuit requires adding two resistors
with value of 1k ohm, 1% to the circuit to facilitate proper
reporting and should be located as close to the sensor as
possible.
* Grounded and foreign voltage states are not a requirement of UL 294
and therefore not verified by UL.
The input circuit wiring configurations shown are supported
but may not be typical.
22 AWG minimum required for input wiring. 18 AWG
recommended if wiring request-to-exit devices in series
with locking hardware.
