Overview
Standard Features
500 Series two-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-wire applications, specifically to meet residential
code requirements.
• Remote maintenance (CleanMe®) reporting and builtin drift compensation reduces false alarms
Kidde is also proud to offer proven technology like CleanMe®,
dust compensation, field replaceable optical chambers, and selfdiagnostics. CleanMe® is only available on the 500 2-wire models
and will communicate with compatible FACPs 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.
7272-1657:

• 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:
•Integral sounder with optional tandem interconnection
•Auxiliary relay Listed for applications such as elevator recall
•Fire system isolated heat integrated with nonlatching single station smoke alarm
•Integral fixed/ROR heat detectors
•Adaptor plate enables replacing 500 Series
with legacy 400 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 sounders emit the temporal 3 pattern and can be easily tandemly 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).

Application
Assembly
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 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
500 Series 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 break-away locking tab, which prevents unauthorized removal. SEMS terminals accept 24 to 12 AWG field wiring.
