Optional Components
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 /2
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).
