Smoke Detection
Overview
GE brand 500 Series two- and four-wire conventional photoelectric
smoke detectors bring together trusted technology and a full line
of features that meet the demands of every type of application. The
500 offers sounders in two- and four-wire applications, specifically
to meet residential code requirements.
The 500 Series also offers choices for optional auxiliary relays and
isolated heat sensors, not available before in the 500 Series.
GE is also proud to offer proven technology like CleanMe®, dust
compensation, field replaceable optical chambers, and self-diagnostics. CleanMe® is only available on the 500 2-wire models and
will communicate to the GE FireworX panels when servicing is
required.
500 Series detectors work on a light-scattering principle. A pulsed
infrared light-emitting diode serves as the light source, and a highspeed photo diode as the sensing element. This design has superior
protection against nuisance alarms caused by dust, insects, RF
interference, and ambient light.
The proprietary optical chamber is field replaceable. In the event of
a confirmed alarm the LED will light continuously. The unit indicates
trouble by flashing the LED every second. This meets the NFPA 72
field sensitivity testing requirements.
Units with built-in 85dBA sounders emit a temporal 3-3-3 tone
pattern when in alarm and will emit a steady tone when the input
power is reversed. All wiring terminates in clamp-type screw terminals. The detectors mount to a standard single-gang electrical box,
a four-inch octagonal, four-inch square electrical box, or WIREMOLD
No. 5739 fixture box.

500 Series detectors are ideal for both retrofit applications and new
installations alike. They are particularly well-suited for installations
where detector reliability is essential, but where analog devices may
not be appropriate or feasible. With their replaceable optical chambers, these detectors are equally well-suited to dusty environments
where detectors require frequent cleaning.

Mounting and Installation
500N detector bases mount directly to standard single-gang electrical boxes, three-inch round, or four-inch octagonal boxes. Detector
heads simply twist onto the base. Heads are equipped with a breakaway locking tab, which prevents unauthorized removal. Terminals
accept 12 to 24 AWC field wiring.
