General
The PW7K1R1 reader interface provides a solution to the OEM system integrator
for interfacing to a TTL (D1/D0, Clock/Data), F/2F or RS-485 device, and door
hardware. It also provides a tri-stated LED control and buzzer control. Two Form-C
contact relay outputs may be used for strike control or alarm signaling. Two inputs
are provided that can be used for monitoring the door contact and request to exit
push button. Input circuits can be configured as unsupervised or supervised. Com-
munication to the controller is accomplished via a 2-wire RS-485 interface. The
PW7K1R1 requires 12 to 24 Vdc for power.
