Edwards Signaling E-PD intelligent analogue optical smoke detector

• Make: Edwards Signaling
• Model code: E-PD
• Type: Smoke

Edwards Signaling E-PD is an intelligent analogue optical smoke detector. It houses a replaceable optical sensing chamber that detects particles produced by smoke. It continuously adjust its sensitivity reference value to compensate for changes in the environment such as the presence of dirt, temperature, and humidity. The detector issues a dirty sensor warning when it reach its preset limit, reducing the chance of a nuisance alarm.
