NAPCO GEM PIR Wireless PIR Transmitter

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 lithium batteries (supplied) for long service life. When battery voltage drops below normal, a low-battery report will be sent to the receiver (replace with Duracell DL123A or Varta/ Power-One 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).
