Passive Infrared Transmitter (PIRT)

Model 8561

The

PIRT

is a space protector which detects

intruders by measuring changes in heat patterns.

When the

PIRT

detects an intruder, it transmits a

signal to the Communication Control Unit. Most

PlRTs

are interior sensors and are only armed

when your system is set to Away.

The

PIRT

is used in areas which would be difficult

to protect with other types of sensors or as addi-

tional protection against intrusion. It is usually

mounted on a wall to monitor an entire room or

hallway.

NOTE: The

PIRT

sends a signal when it first

detects motion and will not send another until it

resets itself. The

PIRT

will reset itself only after

it does not detect any movement for 2-l

minutes.

Replacing

PIRT

Batteries

Batteries should be replaced whenever they are

low. Test the

PIRT

weekly to be sure it is working

properly (see page 22 for procedures used to test

PIRT

battery power and operation). When the

battery is low the

PIRT

sends a trouble message to

the Display Control Keypad.

To Replace Batteries:

To avoid generating a false alarm, you must put

your system in the Test mode (see page 22).

Use a coin to press down on the PIRT release

tab (located in a slot at the top of the backplate).

Pull the top of the backplate away from the

transmitter body to release it. This will send a

Tamper signal to the Test List.

Remove the

PIRT

housing by pulling it up and

away from the bottom of the baseplate.

Remove the batteries and discard them.

Replace the batteries with new 9-volt batteries

(Duracell MN1604, or Eveready 522). Attach the

battery leads and set the batteries into the

transmitter body.

Re-attach the

PIRT

housing to the backplate.

Test the

PIRT

to be sure it operates properly

(see page 22).

Take system out of Test mode (see page 22).
