Alarm Contact Wiring; Control Output Wiring - Honeywell PRO-2200 Installation Manual

12
For Wiring to an RS-485 port:
1. TR+ is the plus side of the transmit and receive differential signal
2. TR– is the negative side of the transmit and receive differential signal.
3. GND is the signal ground. The wiring for this signal is required and NOT optional.
This signal must NOT be connected to chassis GND.
4. Use 24 AWG low capacitance, two twisted-pair, shielded cable (Belden 9842 or
equivalent).
Note: For N-485 Communication Connections, twist the blue pair together and use as the
common; use the orange pair as your data pair, observing polarity. Connect the
external drain shield to the appropriate earth ground on one end.
5. When daisy-chaining RS-485 ports together connect the TR+ wires from the up-
stream and downstream boards to the TR+ terminal and likewise, connect the TR–
wires from the upstream and downstream boards to the TR– terminal.
By factory default J1 is set open. If this board is the last board on the RS-485 bus,
install jumper J1 across both pins (closed). Closing J1 provides the bus termination
required.

Alarm Contact Wiring

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.

Control Output Wiring

Sixteen form-C relay contacts are provided as general-purpose outputs. 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 by the 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.
All 16 relays 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 (i.e., strikes) also causes EMI (electromag-
netic 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
