500N Series
OVERVIEW
500N Series two-wire conventional photoelectric smoke
detectors bring together trusted technology and a full line
of features that meet the demands of both residential and
commercial applications. The 500N offers sounders in two-wire
applications, specifically to meet residential code requirements.
Interlogix is also proud to offer proven technology like CleanMe
dust compensation, field replaceable optical chambers, and
self-diagnostics. CleanMe
models and will communicate with compatible FACPs when
servicing is required.
500N Series detectors work on a light-scattering principle. A
pulsed infrared light-emitting diode serves as the light source, and
a high-speed photo diode as the sensing element. This design
protects 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.*

STANDARD FE AT U R ES
• Remote maintenance (CleanMe®) reporting and built-in drift
compensation reduces false alarms
• Self-diagnostics meets NFPA 72 sensitivity testing requirements
without the need for external meters
• Field-replaceable optical chamber makes service fast and simple
• Large SEMS screw terminals accept 12-18 AWG wire
• Small, low profile design blends with any environment
• Optional auxiliary functions include:
• Integrated sounder with optional interconnection
• Auxiliary relay is NFPA 72 listed for applications such as
elevator recall
• Fire system isolated heat detector, integrated with
non-latching single station smoke detector
• Integrated fixed/ROR heat detector
• Adaptor plate enables replacing legacy 400 Series with 500N
Series smoke detectors
Additional diagnostic information is activated by applying a
magnet near the detector’s integral reed switch. This initiates a
self-diagnostic routine and provides visual indication of sensitivity
level, or if service is required. The magnet test causes the LED
to blink. The number of blink counts corresponds to a smoke
detector sensitivity range.
Models with a built-in 85dB sounder emit the temporal 3 pattern
and can be interconnected using the 405-05 polarity reversal
relay. This enables all detectors to sound when the initiating
detector sounds and meets the requirement of the International
Residential Building Code (IRC).

Assemby
500N 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
typical analog/addressable 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 Series detector bases mount directly to standard singlegang electrical boxes, three-inch round, or four-inch octagonal
boxes. Detector heads simply twist onto the base. Heads
are equipped with a break-away locking tab, which prevents
unauthorized removal. SEMS terminals accept 24 to 12 AWG
field wiring.
