The KI-HCD covers both fire and carbon monoxide in a single addressable head, analyzing its heat and CO sensors independently so it can raise a fire alarm, a life-safety CO alarm, or both, exactly as the readings warrant. That's one detector and one SLC address doing the job of two separate devices on jobs where CO monitoring is mandated alongside fire detection.

Built for the commercial fire installer

Rate-of-rise (15°F/min) and 135°F fixed-temperature heat sensing catches both fast-flaming and slow-building fires, while the CO sensor meets UL 2034 alarm thresholds (70 ppm/60-240 min, 150 ppm/10-50 min, 400 ppm/4-15 min). Continuous self-diagnostics and automatic environmental compensation cut nuisance alarms and maintenance callbacks over the life of the device. Drops into standard KI-series mounting bases, so retrofit jobs reuse existing wiring and box locations.

Key features

  • Dual-hazard detection: independent heat and CO analysis from one addressable head
  • Self-diagnostics with history log: maintenance data stored in non-volatile memory for NFPA 72 reporting
  • Automatic environmental compensation reduces false alarms as the detector ages
  • Drop-in base compatibility: standard (KI-SB), relay (KI-RB), isolator (KI-IB), and audible sounder (KI-ABDT/KI-ABLT) bases
  • 10-year CO sensor life with automatic end-of-life trouble reporting at the panel

System requirements

Requires a Kidde intelligent fire alarm control panel and a KI-series detector base (sold separately). Mounts to standard 1-gang, 3-1/2" or 4" octagon, and 4" square electrical boxes 1-1/2" deep. Sounder base configurations require an FX-T3T4 Temporal Pattern Generator to separate CO and fire tone patterns.

FAQs

Does this detect both fire and carbon monoxide?
Yes. The KI-HCD analyzes its heat sensor independently from its CO sensor, so it can raise a fire alarm, a life-safety CO alarm, or both, from the same address.
What happens when the CO sensor reaches end of life?
The CO sensor has a 10-year life. At end of life the panel shows a COMMON TRBL ACT condition, and the Details button confirms END OF LIFE ACT. This trouble stays active until the detector is replaced.
What base does this detector need?
Any KI-series mounting base: KI-SB standard, KI-RB relay, KI-IB isolator, or the KI-ABDT/KI-ABLT audible sounder bases. Bases are sold separately.
Can this drive a local sounder?
Yes, with a KI-ABDT or KI-ABLT audible sounder base plus an FX-T3T4 Temporal Pattern Generator, which separates the fire (TC3) and CO (TC4) tone patterns.
