The Firex
®
5700 Heat Alarm offers contractors the same reliability and quality they have long depended
on from the leader in fire safety technology. The Firex Heat Alarm, Model 5700, is a fixed temperature
unit that detects heat at 135°F (57°C) or greater. It relies on a thermistor that is sensitive only to temper-
ature. When the temperature reaches 135°F (57°C) or greater, the alarm is triggered. The 5700 requires
120V AC power and includes a 9V battery back-up for added protection in the event of a power failure.
The 5700 heat alarm is interconnectable with other AC/DC Firex heat alarms, smoke alarms, smoke/co
combo alarms, and carbon monoxide alarms. Up to 11 other smoke alarms and smoke/co combo alarms
can be interconnected, and 6 Firex heat alarms and carbon monoxide alarms for a total of not more than
18 devices. Contractors have been installing the best selling Firex smoke alarms for over 20 years and
will appreciate the design similarities when installing Firex heat alarms. Both products utilize a Quick
Connect wire harness, an optional tamper-resist feature and a unique power connector that prevents
interconnection with incompatible heat alarms, smoke alarms or security systems.

Why Install a Firex Heat Alarm?
Some environments can trigger nuisance alarms in conventional smoke alarms due to shifts in
temperature and humidity as well as dust, fumes and insects. Heat alarms are intended for use
in the locations listed below because they are virtually unaffected by these adverse conditions:
• Kitchens • Unfinished Attics • Basements
• Garages • Boiler Rooms • Other areas where high levels
of dust and fumes are present
Heat alarms should always be interconnected
with smoke alarms to provide early
warning when fire is present.
