NOTE: This part is discontinued by the manufacturer. Replace with: SIGA-OSHCD.
The Edwards EST SIGA-PHCD is an intelligent addressable multisensor detector for Signature Series loops. It combines photoelectric smoke, rate-of-rise heat with a 135 °F fixed threshold, and a monitored CO element for broad fire and CO coverage. On-board processing with drift compensation and self-checks helps cut down nuisance alarms, with selectable sensitivity (including day/night) and a clear green/red status LED.
