PRO22R1-Reader Interface | Installation |
Reader Interface (PRO22R1)
The PRO22R1 provides interfacing to a TTL/Wiegand type reader and door hardware as needed, for a single door. The Reader Interface can accept data from a reader with clock/data or Wiegand interface and provides a tri-stated LED control and buzzer control. Two form-C relay outputs may be used for strike control or alarm signaling. Two supervised inputs are provided for monitoring the door contact and exit push button and one input (J3) for enclosure tamper. Communication to the interface is accomplished via an RS-485 interface.
Power, Reader and Door Hardware Wiring
All interconnection to the Interface are via quick-disconnect termi- nal blocks. The Interface requires 12 VDC ±15% for power. The 12 VDC is available for powering a reader.
Reader with TTL (clock/data or wd1/wd0) interface is supported by the Interface.
Two supervised inputs are typically used for door contact and exit push button monitoring. End of line resistors are required for line supervision.
Two form-C relay contacts are provided for controlling door strike or other devices. The contact ratings are different on these out- puts. Load switching can cause contact abnormal wear and pre- mature contact failure. Switching of inductive loads (strike) also causes EMI (electromagnetic interference) which may interfere with normal operation of other equipment. To minimize contact premature failure and to increase system reliability, surge protec- tors should be used (Part #S-4).
