63.1.4 Downstream Reader Communication
The Single Reader Interface Module can communicate downstream with one (1) keypad or card reader. The
J1 interface is a six-wire interface that includes a buzzer control wire and an LED control wire. The buzzer
wire is an open collector that produces 5 VDC open circuit maximum, and 10 mA sink maximum. The LED
wire provides between 0.05 and 3 V, 5 mA source/sink maximum.
Wire the J1 interface using a 24 AWG (minimum) cable at a maximum of 500 feet.
The reader power is a maximum of 80 mA. If the reader requires additional current, connect the reader
power to a +12 VDC terminal on the Single Reader Interface Module.
If you are connecting the reader to a dual reader interface module, each wire should be attached to the
associated connection on the Dual Reader Interface Module board (LNL-1320).
All readers that have a buzzer will beep during pre-alarm when in extended held open mode. This includes
primary and alternate readers. If the reader has two-wire LED control, this feature is disabled. The reader
starts beeping at pre-alarm time and continues to do so until the door is closed or the held open time is hit.
