Locations
Wireless Remote/Transmitter and
Keypad Transmitter
The normal mounting height for the Wireless Remote/Transmitter
and the Keypad Transmitter is between
4-l/2
to
5-l/2
feet for
convenient access to the keypads. Avoid mounting on metal door
or window
frames.
Universal
Transmitterr
Universal Transmitters should be mounted at a height of at least
four feet. A higher
installation
produces the best radiation pattern.
Avoid mounting on metal door or window frames.
Passive Infrared Transmitter (PIRT)
Placement of the PIRT determines the detection pattern.
The PIRT may be mounted either on a flat wall or in
a
comer.
.
A mounting height of
7-l/2
feet provides the best
combination of sensitivity and coverage.Mounting above
this height increases coverage, but decreases sensitivity,
while mounting below this height increases sensitivity, but
decreases coverage.
Allow at least two inches between the unit and the ceiling
to permit servicing.
.
If using the Pet
AIIey
Mask (8560) or Pet
AIIey
Lens
(8561) mount the PIRT 4 to 4
l/2
feet above the floor.
.
Avoid mounting PIRT where direct
sunlight
may strike it.
The customer should be able to identify sun patterns. The
unit should not beng of placed where strong sunlight will strike
directly
on the
face of the
detector.
Be wary of
glass-
topped tables or mirrors that are capable of reflecting
direct sunIight toward the PIRT..Indirect sunlight shining
through windows
wiII
not trigger an
alarm.
