Kidde KI-HFD Intelligent Fixed Temp (135F) Heat Detector

The KI-HFD is an intelligent fixed-temperature heat detector that contains a fixed-temperature heat sensor rated at 135 °F (57.2°C). It does not have a rate-of-rise function. COMPATIBLE BASES and ACCESSORIES: — KI-SB Detector Mounting Base – Standard — KI-SB4 4-inch Detector Mounting Base c/w Trim Skirt — KI-RB Detector Mounting Base w/Relay — KI-RB4 4-inch Detector Mounting Base w/Relay, c/w Trim Skirt — KI-IB Detector Mounting Base w/Fault Isolator — KI-IB4 4-inch Detector Mounting Base w/ Fault Isolator, c/w Trim Skirt — KI-ABST Audible (Sounder) Base for Fire Detectors — KI-ABLT Low Frequency Audible (Sounder) Base for CO and Fire Detectors — KI-ABDT Audible (Sounder) Base for CO and Fire Detectors — GSA-LED Remote Alarm LED (not for EN54 applications) — GSA-TS4 Trim Skirt (supplied with 4-inch bases) — GSA-TS Trim Skirt (optional for non 4-inch bases) NOTE: Replaces Edwards EST GSA-HFS and V-HFD. KI detectors are electrically backwards compatible with V Series and GSA Series detectors and can be mixed on the same data loop as their equivalent counterparts however, all KI detectors will require a KI series detector base.
