System Sensor 5600 Series Heat Detectors - Manual (Page 2)

Self-Restoring Rate-of-Rise (ROR) Sensor
The rate-of-rise element responds to a rapid rise of
temperature, approximately 15ºF (8.3ºC) per min-
ute. As the temperature rises, the air within the
sealed chamber expands. Should the chamber air
expand faster than it can escape through the cali-
brated vent, the diaphragm is depressed, and the
electrical contact closes the circuit.
NOTE: Only the ROR element of 5600 series com-
bination fixed temperature/ROR models (5601P,
5602, 5621, and 5622) are self-restoring, and may be
tested using a hair dryer or heat gun. When testing
the ROR element, to prevent the activation of the
fixed temperature element, the heat source must not
exceed the fixed temperature rating of the detector.
Mounting Bracket
All 5600 series detectors are equipped with a mount-
ing bracket that includes mounting slots to accom-
modate single-gang, 3 1 ⁄
2
˝ octagonal, and 4˝ octagonal
electrical boxes, as well as 4˝ square boxes equipped
with a plaster ring (Figure 1). The mounting bracket
is reversible to accommodate flush-mount and sur-
face–mount installations (Figure 2).
Wiring Installation Guidelines
All wiring must be installed in compliance with the
National Electrical Code, applicable state and local
codes, and any special requirements of the local
Authority Having Jurisdiction. Proper wire gauges
should be used. The conductors used to connect
heat detectors to the alarm control panel and ac-
cessory devices should be color-coded to reduce the
D500-46-00 2 I56-2175-003R
