Heat Detectors
Series 600
The Series 600 Heat Detector is attractive, durable and
features combination rate-of-rise and fixed temperature
operation. Heat detectors are available in 135°F and 200°F
temperatureratings.
Rate-of-rise detects heat by quickly responding to a rapid
temperature increase. Rate-of-rise units have a wide spacing
allowance of 50-foot centers. See specification table for
details.
Fixed temperature reacts to heat by responding to a specific
temperature setting.
Series 600 Detectors use the same reliable pneumatic rate-of-
rise element of former models, but offer added aesthetic
appeal.
The pneumatic rate-of-rise element responds to a rapid rise in
temperature, approximately 15°F. (8°C) per minute, by
expansion of air within the sealed chamber faster than it can
escape through a calibrated vent. The resultant increase in
pressure depresses the diaphragm, causing the electrical
contact to close the circuit.
The fixed temperature element uses a fusible alloy. When
activated, the external heat collector drops away to provide
quick visual confirmation that the element has operated.
The units protrude only 1-3/8 inch from the ceiling surface with
a junction box mounting. They have pleasing contours and an
all-white finish that conforms to ceiling aesthetics.
Installation
Each detector includes a patented reversible mounting plate.
In one position, it easily attaches to 3.25" or 4" octagonal box,
or plaster ring.
In reverse, the plate can be used for open wiring without a
junction box. A1/4" space between detector and mounting
surface allows for wire connections. All mounting screws are
concealed.
The detector attaches easily to the mounting plate with a push
and twist motion. No tools are required.

The Heat Detectors Series 600 are supplied
with the following standard features:
• Rate-of-Rise and Fixed Temperature
• One or Two-Circuit, Normally Open
• Easy Installation
• Low Profile
• Visual Indication
• Operation Testing
Description
Mounting plate is molded of white self-extinguishing thermo-
plastic rated at 221°F (105°C). The plate is extremely strong
yet adapts to uneven mounting surfaces.
Series 600 Testing Methods
Models 601/621 and 602/622 can be tested by the quick
application of heat from any convenient source. A portable hair
dryer is recommended. However, do not apply heat that
exceeds the fixed temperature rating of the detector.
Models 603/623 and 604/624 cannot be tested. However, the
fusible alloy element used is considered so reliable that testing
is not necessary.

Important Special Notes
Application: Heat detectors should be used for property
protection. Reliance should not be placed on heat detectors for
LifeSafety.
CAUTION: When life safety is involved, smoke detectors
MUST also be sed. Detectors m st not be painted.
Battery Back-Up: Heat detectors should be electronically
supervised with battery back-up at the panel.
The rate-of-rise mechanism may be subject to reduced
sensitivity over time.Annual testing of the rate-of-rise mecha-
nism is recommended.
