Outdoor Receiver Installation
Receiver Spacing: Receivers should be mounted every 91.5 m (300 ft.). It is very important to maintain as
consistent spacing as possible, as this will ensure optimum signal locating. The more receivers that can detect a
transmitted signal, the more accurate the locating will be. Each receiver should have a clear line-of-sight of the
intended protection area.
Mounting Height: Receivers should be mounted 3 m (10 ft.) above grade. Maintain a mounting height that is as
consistent as possible to ensure optimum signal locating.
Overhangs/eaves: Receiver locations should be below building overhangs and eaves. Most transmissions will
occur a few feet (1 m) above grade; mounting above overhangs and eaves could result in inaccurate signal
locating. Be especially careful around metal roofs as these can block the signal.
Select a mounting location that:
•
provides a clear line-of-sight of the protected area,
•
is away from metallic objects such as chain-link fences and electrical transformers. If coverage is required
near such items, testing should be performed near these items to determine the potential need for additional
receivers,
•
is 3 m (10 ft.) above grade,
•
is not at a barrier where is it important to resolve which side an alarm location is on,
•
is easy to service, and
•
will not be damaged by tampering.
Wiring
CAUTION:
Switches and Jumpers
Loop Address
The Rotary Switch is used to select the loop address. This is the address that is reported to the transponder the
receiver is connected to. Each device on a loop should have its own address. Only addresses 0 through 7 are
valid. Do not use addresses 8 and 9.
Apply power only after all connections have been made and inspected.
Connect wiring as shown:
