AW-D138 is a smoke with fixed temperature and rate-of-rise heat detector. The detector uses an optical sensing chamber to detect smoke and a fixed-temperature heat sensor to detect heat from fire. It is designed to provide open area protection . The red LED on the detector provides a local 360°visible alarm indication. The detector that initiated the alarm condition will have its red LED latched until reset by panel.
Features
1. Low Standby current for continuous monitoring
2. Two-wire connection
3. Dual LED design provides 360° viewing angle
4. Meet requirement of EN54-5:2017 & EN54-7:2018
