The GEM-P1664 Hybrid 8 to 64-Zone Control/
Communicator features 8 zones expandable 
to 64 zones with multiplexing and supports 
proven, reliable, NAPCO crystal-control 
transmitters and uses advanced helically-filtered 
receivers, too. Supporting up to 64 user codes 
and 8 16 relays, the GEM-P1664 comes in two 
configurations suitable for 

EN50131-1

 and/or 

CE installations

. This Gem control features easy 

“Self-Programming Plus” keypad programming 
(for all zones), which includes new alpha 
keypad question-prompts, even for setting test 
timer, fire zones and exit/entry and follower 
zones. Additionally, the panel can be remote 
up/downloaded using easy-to-use NAPCO 
Quickloader Software (V5.0 or greater) with true 
Windows-style functionality, including cut/paste, 
drop/drag, etc.
