DP721R - 700 Series Conventional Optical Smoke Detector w/ Relay Output

Description

The DP721R is an optical smoke detector with field exchangeable optical chamber and a built in potential free relay for local switching applications. The detector detects the presence of smoke in the environment using the Tyndall Effect, by light scarring measurement in an optical chamber.

700 Series detectors continually monitor their own sensitivity and operational status. Once a day they perform a full diagnostic test that includes dynamically testing the sensing chamber and internal electronics. Any abnormal statuses are reported locally and to the panel.

Automatic self diagnostics: Dynamic full detector and sensitivity test
Manual self diagnostic with visual sensitivity indication
Field sensitivity testing without external meters
Field exchangeable and disposable optical chamber
High false alarm immunity
Floating background with drift compensation
Separate fire and fault LED
12 - 24 VDC operation
Polarity insensitive
Full range: optical, heat and optical/heat multi criteria sensor
EN54 approved and CPR certified
