GENERAL DESCRIPTION

GENERAL DESCRIPTION
The GEM-PIR is an advanced PIR sensor designed for use
with Napco's GEM-Series wireless receivers. The unit is
powered by two 3-volt Type DL123A lithium batteries (sup-
plied) for long service life. When battery voltage drops below
normal, a low-battery report will be sent to the receiver.
Coding switches are not used in the GEM-PIR. Each
transmitter has a unique factory-programmed RF ID code
(printed on the unit) that distinguishes itself to the receiver.

proceed as follows.
1. To open the case, insert a small screwdriver in the slot
at the bottom and push up slightly. Remove the front cover.
2. Push up on the lower edge of
the Lens Support until it is clear of
its retainers, then pull out the sup-
port from the bottom. Be careful
not to dislodge the LED jewel.

Note:
reinsert it with the small index key
positioned at the top.
3. Slide out the lens and install
the replacement.
4. Replace the Lens Support:
Slip the Lens Support under the top guides with its two tabs
straddling the LED jewel, then push in at the bottom until
the Lens Support snaps into place.

INSTALLATION

INSTALLATION
An assortment of ''push-thru'' holes is provided in the rear
case for wall or corner mounting. Install the two lithium
batteries as shown in the illustration below.
Loosen the Height Lock Screw and set the board's height
scale to the mounted height of the unit. Retighten the screw.
To reduce range if necessary, set height scale at a higher
number than actual mounting height of unit. Do not point
the unit at sources of heat, such as radiators, space heat-
ers, etc.
Note:
Note: In UL burglary installations, the burglary output
must be programmed for all protective devices.

WALK TESTING

WALK TESTING
The LED will light in the Walk-Test Mode only. Allow at least
3 minutes for the unit to settle. Press the Walk-Test Button to
access the Walk-Test Mode for 5 minutes.
Walk out to the maximum range and walk across the field
of coverage. The LED will light whenever motion is de-
tected. Check for environmental disturbances with all dis-
ruptive devices (heaters, air conditioners) on and no human
activity within the coverage area. Adjust beams laterally by
removing the Lens Support (see REPLACING THE LENS)
and sliding the lens slightly left or right. To block a problem
zone, apply a piece of lens foil (supplied) to the inside
segment of the lens representing that zone.
