Specifications

Napco’s crystal-control Gemini wireless
products have been proven by an
independent testing laboratory to
outperform competitive products, with
long-range RF reliability, as much as 50%
higher than other top brands.
Gemini Transmitters range from keyfobs
and panic buttons, to recessed door
and surface-mount window/door
contacts, to wireless PIR, PIR/pet and
dual sensors, and from wireless smokes
and glass breaks to heat detectors.
Simply put, Gemini’s uncommon crystal-
control precision and omnidirectional
circuitry, ensures the wireless/hardwire
systems you provide your customers
will dependably deliver the security and
trouble-free, peace-of-mind they deserve
for many years to come.
