NAPCO GEM-PIR - Wireless PIR Transmitter Manual

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 instructions for entering this six digit hexadecimal code and checksum digit into the panel; be sure to enter all numbers and/or letters, 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. To install one of the accessory lenses, 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 support 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 Support.

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 burglary 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 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 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 representing 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.
