Ademco Wireless Heat Detector - 5809SS

Be the first to review this product

The Honeywell 5809SS Rate-of-Rise Heat Detector is a wireless device used with alarm systems that support Honeywell's 5800 series devices.

Brand: Honeywell Intrusion
Part Number: 5809SS

Availability: This item requires 2 business days to process.




The 5809SS combines a rate-of-rise sensor and a fixed temperature sensor in one device. The rate-of-rise sensor detects a rapid rise in temperature and signals an alarm if the rise is 15°F (8°C) or more per minute. Fires typically cause a rapid rise in temperature in the surrounding area. The fixed temperature sensor will signal an alarm when the ambient temperature rises above 135°F (57°C).

IMPORTANT: The 5809SS will be permanently damaged if stored, shipped, or installed in environments where the temperature exceeds 100°F (38°C). If the metal disc is detached, the detector has exceeded 135°F (57°C) and must be replaced.

Heat detectors should be used for property protection. Reliance should not be placed solely on heat detectors for life safety. When life safety is involved, smoke detectors MUST also be used.

Detectors MUST NOT be painted.
