Getting Started
Review this manual before you begin to determine
hardware and wiring requirements for the features you
want to use. Have the following handy as you read
through the manual:
• Program Record Sheet (35120)
• Program Entry Guide (35121)
• Security System User’s Guide
Mount the Enclosure
Open the cover to access the mounting holes in the rear of
the enclosure. Note the wiring label on the inside of the
enclosure cover.
Mount it in the desired location. Be sure there is enough
clearance to open the door for maintenance. Mount the
panel into the enclosure a shown in Figure 1, below.
Insert the two support posts in the retainer holes. Slide the
top of the panel into the two retainer tabs. Once in the
tabs, the panel will rest on the two support posts. Secure
the panel with the supplied screws.
Run the Premises Wiring
Run the necessary wiring throughout the premises and
pull the wires into the enclosure. Do not make any
connections yet.
Wire Length
Wire Length for points is limited only by the resistance on
the loop and potential EMI (Electro Magnetic Interference)
problems.
Wire resistance on the Point 1 sensor loop must be less
than 50
Ω
. Measure the wire resistance before installing
smoke detectors. Short the end-of-line resistor before
metering the wire.
Resistance on the sensor loops for Points 2 to 6 must be
less than 100
Ω
with the end-of-line resistor shorted and
the detection devices connected.
Maximum wire length for the transformer is 50 feet (18
AWG, stranded).
Maximum wire length for all keypads is 500 feet (22
AWG).
EMI (Electro Magnetic Interference)
AC wiring can induce EMI (both noise and low level
voltage) into adjacent wiring. Run phone and sensor loop
wiring away from AC conductors, including the transformer
wire. Run keypad wiring away from AC and phone wiring.
EMI may also occur if you install the panel or run system
wires near the following:
• Computer network system
• Fluorescent fixtures
• Telephone cabling
• Ham radio transmitter site
• Heavy machinery and motors
• High voltage electrical equipment
• PBX telephone system
• Public Service (police, fire departments, etc.) using
radio communications
• Radio station transmitter site, or other broadcasting
station equipment
• Welding shop
If you think that EMI may be a problem, use shielded
cable. The drain wire for the shielded cable must have
continuity from the earth ground terminal on the control
panel, to the end of the wire run.
