Never power auxiliary
devices such as
power door strikes, sirens, gate
operators, cameras, or any
other equipment from the same
power supply as AI devices are
connected to.
Never power auxiliary devices
such as power door strikes,
sirens, gate operators, cameras,
or any other equipment from the
controller. Only AI devices should
be powered from the controller.
These auxiliary devices should
be powered as per manufacturer
instructions with considerations
for amperage/current draw and
voltage requirements.
Powering auxiliary devices on
the same circuit as AI devices
or from the controller can cause
voltage drop in the system leading
to device lockup and intermittent
problems.
Power
Reliable equipment operation depends on a noise-free uninterrupted
source of power. The battery back-up feature is provided primarily
to preserve the integrity of the memory database and operation of
the controller. It does not guarantee operation of the gate motor or
door actuator for emergency situations in the event of a power loss
or equipment failure. It is the sole responsibility of the purchaser to
provide for and facilitate manual nonelectrical emergency means of
exit in the event of a power failure. Contact your local dealer/installer
for options and availability. Verify that there are enough 120V outlets
in the ofce (and/or maintenance rooms) where the equipment will be
located to support the equipment needs. Also, consider other ofce
equipment and electronics that require power such as copiers, fax
machines, computers, telephones, lights, water coolers, etc. Each
power supply, controller, computer, video monitor, etc. requires at
least one outlet. We recommend a minimum of two, 4-outlet stations
for the equipment; however your site may require more.
Auxiliary Security Devices
Power for door strikes, gate operators, sirens, cameras, and any
equipment other than the controller and AI devices must be provided
by separate power supplies. Never power a door strike or siren from
the same power supply to which an AI device is connected. This
must be considered when planning power needs for a site.
Wire
Refer to Wire Recommendations for recommendations on the proper
wire to be used with the controller. Be sure to plan on enough wire
plus an additional 10% – 15% for safety. Take into consideration the
linear distance, distance in rise for multiple oors, or the distance in
depth for burial when ordering wire. Be sure to pull an extra 10 feet of
wire at each end of a wire pull during installation. This allows enough
wire to meet the needs of the site without having to splice extra
wire. When installing AI devices, trim the excess, leaving a one-foot
service loop. Also, pull an extra 18 AWG 4-conductor wire throughout
the site and set aside several extra sets of 24 AWG 50-conductor
wires for future add-ons, maintenance, or repair of wiring. It is less
expensive and easier to do this up-front than to try and pull wire later.
Especially if additional construction is planned. PTI Security Systems
can supply the necessary wire for your needs. We recommend that
you use this wire as we have tested it over the years and know that,
if installed correctly, it works with our system.
