ROR Heat Detector

RD - 914L

Operation theory when ambient temperature rises rapidly and has reached the fire disaster standard, the air inside the detector will inflate and presses the copper diaphragm for conduction. When a slower temperature change occurs, the expanded air escapes through a bleeding hole to keep pressure balanced so that the fault alarm never occurs.

Features

Dual LEDs for 360-degree visibility.

Rate of rise heat detector detects intense fires by quickly responding to rapid temperature increases.

Mechanical operating principles ensure long-term durability and the least malfunction.

Self-restoring function ensures the elements repeatedly use.

Electrical contacts with Silver-palladium alloy to conduct electricity excellently.

The exhaust valve of the ROR Heat Detector part uses an optical fiberglass capillary tube that's heat-resistant and moisture- proof to avoid false alarms.
