Input Circuit Wiring
2.11 Input Circuit Wiring
Typically, these inputs are used to monitor door position, request to exit, or alarm
contacts. Input circuits can be configured as unsupervised or supervised. When
unsupervised, reporting consists of only the open or closed states.
When configured as supervised, the input circuit will report not only open and closed,
but also open circuit, shorted, grounded, and foreign voltage.
Note:
Grounded and foreign voltage states are not a requirement of UL 294 and
therefore not verified by UL.
A supervised input circuit requires two resistors be added to the circuit to facilitate
proper reporting. The standard supervised circuit requires 1K Ohm, 1% resistors and
should be located as close to the sensor as possible. Custom end of line (EOL)
resistances may be configured via the host software.
Note:
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:

2.12 Relay Circuit Wiring
Two Form-C contact relays are provided for controlling door lock mechanisms or
alarm signaling devices. The relay contacts are rated at 2 A @ 30 VDC, dry contact
configuration. Each relay has a Common pole (C), a Normally Open pole (NO) and a
