The ESL photoelectric smoke detector is a side

 

mounted light-scattering optical senor that provides outstanding stability and excellent response to a wide range of fires.

 

A pulsed ingared LED light source and a high-speed photodiode sensing element are housed in an omni-drectional sensing chamber which is protected by an insect screen.The chamber is not affecled by ambient ligh . For easy cleaning , the chamber unsnaps and is field-replaceable .

 

The Model 711UT , photoelectric smoke rate-of-rise heat detectors include fast response algorithms for a quick response to both flaming and smoldering fires. As soon as the heat sensor detects a rapid rise in temperature ,the sensitivity of the photoelectric sensor increses.

 

The ESL ionization smoke detector is a single source,dual-chamber detector that provides excellent response to both visible and invides excellent response to both visible and invisible combustion particles from all types of fires. The detector is exceptionally stable in all environments, including high altitudes and wind gusts. lt also features an insect screen to protect further against nuisance alarms.

 

ESL 700 Series smoke detectors are the industry s first conventional self-diagnostic detectors specifically designed for the demands of commercial and industrial environments. If the detector drifts out of its UL Listed se sitivity range or fails internal diagnostics, the alarm LED flashes once a second to indicate trouble.This meets NFPA 72 field sensitivity testing requirements without the need for external meters.

 

And, as they get dirty, the 700 Series detectors automatically adijust the alarm threshold through built-in drift compensation.
