Answer:
This unit integrates both a 59°C fixed-temperature trigger and an 11.1°C/min rate-of-rise sensor, paired with polarity-free 2-wire installation and dual LEDs providing 360-degree visual indication.
This conventional heat detector incorporates dual thermal sensing technology alongside site-friendly installation features:
- Dual Detection Mechanism: Alarms on rapid temperature increases exceeding 11.1°C (20°F) per minute (Rate of Rise) or when ambient temperatures reach the static limit of 59°C (138°F). This protects against both fast-flaming thermal surges and slow smoldering conditions.
- Polarity-Free Wiring: Eliminates termination and polarity errors on initiating zone circuits during field installation.
- 360-Degree Status Indication: Dual LEDs mounted on the low-profile housing provide omnidirectional visibility of standby supervisory polling and latched alarm states from floor level.
- Reset Threshold: The detector latches in alarm upon activation and resets when loop voltage drops below 1V DC from the host control panel.
