inputs have default functional definitions, but all eight can be configured to monitor
general-purpose sensors.
By default, Input 0 is defined as the Door Status Input corresponding to reader 1 and
Input 1 is defined as the REX input corresponding to reader 1. Also by default, Input 2
is defined as the Door Status Input corresponding to reader 2 and Input 3 is defined as
the REX input corresponding to reader 2. Inputs 4, 5, 6 and 7 are general purpose
inputs that can be used to monitor sensors or as control inputs. Inputs 6 and 7 are not
accessible when the board is rack mounted.
Inputs TMP and PFL are typically used for monitoring cabinet tamper and power
failure respectively. These two inputs are not supervised and are not accessible when
the board is rack-mounted. These inputs were primarily provided for the case when
this board is mounted remotely and cannot take advantage of the tamper and power
fail detect inputs on the controller board. If these inputs are not used, install a short
piece of wire at the input to indicate safe condition.
Input configuration including debounce and hold time is set via host software.
Control Output Wiring
Six form-C relay contacts are provided for controlling door strike or other devices.
Each may be assigned to door-related functions or general-purpose output. They are
configurable as standard (energize to activate) or fail-safe (de-energize to activate) via
host software.
The energized or ON time of each relay can be configured using Pulse control for
single or repeating pulses via host software. The energized or ON time for a single
pulse can be extended up to 24 hours. For repeating pulses, the on/off time can be
defined in 0.1 second increments and be repeated up to 255 times.
Relays 0 and 2 are rated for and normally used to control the door locks associated
with readers 0 and 1 respectively. While Relays 0 and 2 are sized to handle the typical
loads generated by electrical locks, load switching can cause abnormal contact wear
and premature contact failure. Switching of inductive loads (i.e., strike) also causes
EMI (electromagnetic interference) which may interfere with normal operation of
other equipment. To minimize premature contact failure and to increase system
reliability, a contact protection circuit is highly recommended. The following two
circuits are suggested. Locate the protection circuit as close to the load as possible
