GEM-PIR
Wireless PIR Transmitter
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 supplied 3-volt lithium batteries (estimated battery life 3
years). When battery voltage drops below normal, a low-battery
report will be sent to the receiver (replace with Duracell DL123A,
Varta/Power-One CR123A or Panasonic CR123A only). 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. (
Note:
See control-panel in-
structions for entering this six digit hexadecimal code and check-
sum digit into the panel; be sure to enter all numbers and/or let-
ters, including leading zeros, if any).

REPLACING THE LENS
The lens is ''sandwiched'' between the front case and a Lens
Support insert, which also serves to hold the LED jewel in place.

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: If the LED jewel pops out,
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. Removing Lens Sup-
port.
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 heaters, etc.
Note:
In UL burglary installations, the bur-
glary output must be programmed for all protective devices.
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 ac-
cess 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 detected.
Check for environmental disturbances with all disruptive 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 represent-
ing that zone.
SETTING THE OPERATING MODE
The GEM-PIR comes set for operation in the Signal Selective
Processing (SSP) Mode. To change to the fixed 2-pulse bipolar
mode for use with the Long-Range Lens* (LENS840), Barrier
Lens* (LENS818) or other lens with a limited number of beams,
remove the Response-Mode Jumper, J1.
