Alarm Contact Wiring; Control Output Wiring - Honeywell Pro-Watch 7000 Install Manual

Alarm Contact Wiring

Inputs 0 to 15 may be configured to use normally open or normally closed contacts
and non-supervised or supervised (with standard ±1 tolerance 1K ohm). All 16
inputs can be configured to monitor general-purpose alarm sensors or can be
used as control inputs.
Additional 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 are used 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 sensitivity and hold time is set via host software.

Control Output Wiring

Two form-C relay contacts are provided for controlling other devices. Each may be
assigned to a general-purpose output. They are configurable as standard (energize
to activate) or fail-safe (de-energize to activate) by the 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 of 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 1 are rated for dry contact signal or load switching. While they are
sized to handle typical loads, load switching can cause abnormal contact wear and
premature contact failure. Switching of inductive loads (e.g., strikes) 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 circuit
is suggested. Locate the protection circuit as close to the load as possible (within
12 inches [30cm]); the effectiveness of the circuit decreases as the distance from
the load increases.
