System Sensor 5601P is a 5600 Series single-circuit mechanical heat detector, normally open, rated 135°F (57°C) and activating on either fixed temperature or rate-of-rise.
The 5600 Series is a low-cost means of property protection against fire and suits non-life-safety installations where smoke detectors are inappropriate, such as garages, boiler and mechanical rooms, attics and kitchens where dust, steam or fumes would cause nuisance smoke alarms. The 5601P is the plain-housing member of the family, with no exterior alphanumeric marking, so System Sensor positions it for residential installations where the lettered models would be visually intrusive. The rate-of-rise element is restorable, an external collector drops on activation to identify the detector in alarm, and a reversible mounting bracket permits flush and surface mount back box installations.

Installation notes
- The 135°F models (5601P, 5603, 5621, 5623) are limited to a 100°F installation temperature. In hotter spaces use a 194°F model such as the 5602.
- The rate-of-rise element resets after field testing, but once the fixed-temperature element has operated and the collector has dropped, the detector must be replaced.
- Because the 5601P has no lettering, label the device or record the model at commissioning.
- The 50 x 50 foot spacing applies to a 10-foot ceiling; refer to NFPA 72 for reductions at greater heights.
- Where an auxiliary contact is needed, use the dual-circuit 5621.
