System Sensor 5602 Sensor

The System Sensor 5602 is a professional-grade 5600 Series mechanical heat detector designed for high-temperature environments where standard smoke detection is impractical. This single-circuit unit features a 194°F fixed temperature thermal sensor integrated with rate-of-rise technology, activating when ambient heat increases by 15°F or more per minute. Engineered for durability in mechanical rooms, kitchens, and industrial bays, the mechanical heat sensor utilizes a bimetallic leaf spring for the rate-of-rise element and a temperature-sensitive solder thin-film for the fixed alarm point.

Installation is streamlined via a reversible mounting bracket compatible with 3.5-inch and 4-inch octagonal, single-gang, or 4-inch square junction boxes. The System Sensor 5602 utilizes terminal screws with Easy-to-Wire SEMS plates to maintain secure 14–22 AWG wire connections. A high-visibility collector drop indicator provides immediate post-activation identification, while alphanumeric lettering on the exterior ensures the 194 degree F fixed heat alarm point is clearly identifiable from the floor during routine inspections.

Key Benefits for Contractors:

• Dual-Mode Detection: Provides comprehensive thermal monitoring using both rate-of-rise alarm condition and fixed-point activation.
• Flexible Mounting: The 5600 Series bracket supports flush or surface mounting without additional adapters.
• High-Temperature Reliability: The 194°F (90°C) rating is ideal for attic and warehouse applications where high ambient temperatures cause nuisance tripping in lower-rated sensors.
• Maintenance Identification: An internal collector drops down after activation to provide a permanent visual signal of which unit triggered the circuit.

Common Questions:

Is the System Sensor 5602 a self-restoring detector?
The rate-of-rise element is self-restoring; however, if the 194°F fixed temperature threshold is reached, the internal solder melts and the unit must be replaced.

How do I confirm the temperature rating after installation?
The model number and temperature rating are clearly printed in large alphanumeric lettering on the face of the detector for quick field verification.

Can this be used on a 2-wire or 4-wire fire alarm circuit?
As a mechanical single-circuit contact closure device, it functions as a dry contact and is compatible with any fire alarm control panel utilizing an initiating device circuit (IDC).
