Overview
Standard Features
Kidde brand conventional photoelectric smoke detectors include
an interchangeable head and base, with a light-scattering optical
sensor. They provide outstanding stability and excellent response
to a wide range of fires.
• Self-diagnostic capabililty continually monitors operation
A pulsed infrared LED light source and a high-speed photodiode
sensing element are housed in an omnidirectional sensing chamber protected by an insect screen. For easy cleaning, the detector
features a field-replaceable optical chamber.
• Automatic drift compensation
Model 721UT photoelectric detectors include integral fixed
temperature and rate-of-rise heat detectors. The 721UT provides
remote alarm and trouble LED driver outputs. Also available is
the 713-5U electronic heat detector head for areas too dusty for
smoke detection.
• Advanced alarm verification nuisance alarm immunity
700 Series smoke detectors were the industry’s first conventional
self-diagnostic detectors specifically designed for the demands of
commercial and industrial environments. If the detector drifts out
of its UL Listed sensitivity range or fails internal diagnostics, the
alarm LED flashes once a second to indicate a trouble condition.
This meets NFPA 72 field sensitivity testing requirements without
the need for external meters.
Engineering Specifications
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.
And, if they become dirty over time, the 700 Series detectors
automatically adjust the alarm threshold through built-in drift compensation. If the detector ever does need to be cleaned, the patented field replaceable optical chamber makes cleaning a snap.

• Meets NFPA 72 sensitivity test requirements
• Head and terminal base design (base sold separately)
• Field-replaceable optical chamber
• Low-profile design blends into the ceiling
• Continuity switch in base to ease installation
• Extensive two-wire compatibility listings
The 700 Series photoelectric smoke detector, is a low-profile, selfdiagnostic, two-wire detector that monitors its own sensitivity and
operational status. The detector meets NFPA 72 field sensitivity
testing requirements without the need for external meters. Built-in
drift compensation automatically adjust the sensitivity if the detector gets dirty. The 700 Series features an alarm verification feature
to further reduce the chance of a nuisance alarm. Normal sensing
occurs every 9 seconds. This rate doubles when a signal exceeding the alarm threshold value is sensed. Two additional successive
signals above the threshold level initiate an alarm. The patented
optical sensing chamber is field replaceable, allowing quick and
easy cleaning and maintenance.
A manually operated switch between terminals 1 and 2 establishes
continuity across the alarm initiating circuit at initial installation of
the base simplifying testing without the smoke head in place. The
switch automatically opens when a detector head is plugged in.
