Universal Transmitterr

Passive Infrared Transmitter (PIRT)

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 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.

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.
