Edwards 700 Series
Conventional Fire Alarms
Smoke Detectors
700 Series
Edwards 700 Series smoke detectors are suitable
for use in 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 trouble. This
meets NFPA 72 field sensitivity testing requirements without the need for external meters.
Features and Specifications
• Self-diagnostic capability continually
monitors operation
• Built-in drift compensation
• Field-replaceable optical chamber
• Low-profile design blends into the ceiling
• Advanced nuisance alarm immunity
• Meets NFPA 72 field sensitivity testing without
the need for external meters
• Extensive two-wire compatibility listings
• White head and base
• Operating temperature range: 32°F to 120°F
(0°C to 49°C)

FIRE ALARMS
The Edwards photoelectric smoke detector is an
interchangeable head and base detector with a
light-scattering optical sensor. A pulsed infrared
LED light source and a high-speed photodiodesensing element are housed in an omni-directional
sensing chamber protected by an insect screen.
The chamber is not affected by ambient light.
The detector features a field-replaceable optical
chamber to simplify cleaning. The 721UT
photoelectric detector includes integral fixed
temperature heat detectors.
Applying a magnet near the detector’s integral
reed switch activates a self-diagnostic routine
that provides visual indication of sensitivity level,
or if service is required.
Built-in drift compensation allows the detector to
automatically adjust its sensitivity over time as it
becomes dirty.
