8. Input Circuit Wiring:
The eMAX-LP1502 provided 8 inputs that are typically 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 circuit, grounded*, and foreign voltage*. 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:
