LNL-1320-S2RP Dual Door Control Module
36.2.1 Supervised Inputs wired to the LNL-1320-S2RP
Supervised inputs for the door position monitor and REX switches are wired to TB1 for the first reader, and
TB3 for the second reader. Two sets of End-Of-Line (EOL) resistor pairs are supported by the S2RP board.
Either two 1K ohm resistors, or a 6.8K and 18K ohm resistor set must be installed as shown in the following
figures. Install the EOL resistors as close to the switch as possible to maximize supervision's effectiveness.
In addition to detecting contact open or contact closed, the LNL-1320-S2RP also monitors for the following
abnormal circuit conditions: open circuit, shorted circuit, grounding of either side of the circuit, or the
introduction of a foreign voltage.
Note: Grounded and foreign voltage states are not required by UL 294 and therefore not verified by
UL.
