The KIR-PHCD puts three detection technologies into one head - photoelectric smoke sensing, rate-of-rise and fixed-temperature heat detection, and electrochemical CO monitoring - so you cover smoke, heat, and carbon monoxide from a single SLC address on the loop. Rotary switches on the detector set the address (1-250), no programming tool needed at the head.

Built for the commercial installer

Designed for Kidde FX Series intelligent fire alarm control panels, the KIR-PHCD draws just 32 µA in standby and runs on standard SLC loop power (15.20-19.95 VDC). Multi-criteria sensing from a single point reduces false alarms while maintaining broad coverage across smoke, thermal, and CO events. Automatic environmental compensation adjusts sensitivity over time, so drift from dust accumulation or environmental changes won't trigger nuisance alarms or require manual recalibration.

Listed to UL 268, UL 521, and UL 2075, with CO alarm sensitivity evaluated to UL 2034 limits. Mounts on standard electrical boxes with any compatible Kidde intelligent base, including sounder bases for local CO and fire notification.

Key features

  • Three sensors, one address: photoelectric smoke, thermal heat (rate-of-rise at 15°F/min plus fixed at 135°F), and electrochemical CO detection
  • Rotary addressing (1-250): set the SLC address at the detector head with no programming tool required
  • Automatic environmental compensation: drift correction keeps sensitivity calibrated over the life of the detector
  • Mounts to standard electrical boxes: 1-gang, 3.5" or 4" octagon, and 4" square with compatible Kidde bases
  • Multiple base options: standard, relay, fault isolator, and audible sounder bases available for flexible system design
  • Testifire compatible: field-testable with Testifire 1000 and 2000 multi-stimulus test tools

System requirements

Requires a Kidde FX Series intelligent fire alarm control panel and a compatible detector mounting base (KI-SB standard base or equivalent). Each detector occupies one SLC address, with up to 250 addressable devices per loop.

FAQs

What panels is the KIR-PHCD compatible with?
The KIR-PHCD is designed for Kidde FX Series intelligent fire alarm control panels. Each detector occupies one SLC address, with up to 250 addressable devices per loop.
What types of detection does the KIR-PHCD provide?
Three sensors in one head: photoelectric smoke, rate-of-rise and fixed-temperature heat, and electrochemical CO. Multi-criteria detection reduces false alarms while covering smoke, thermal, and carbon monoxide events.
What mounting bases are compatible?
KI-SB (standard), KI-SB4 (4-inch), KI-RB (relay), KI-RB4 (4-inch relay), KI-IB (fault isolator), KI-IB4 (4-inch isolator). Sounder bases KI-ABLT and KI-ABDT plus tone generator FX-T3T4 also available for CO and fire notification.
How do you set the address on the detector?
Rotary address switches on the detector head allow setting SLC addresses from 1 to 250 without a separate programming tool. Set the address before mounting the detector on the base.
How do you field-test this detector?
Compatible with Testifire 1000 and Testifire 2000 multi-stimulus test tools for smoke, heat, and CO function verification in the field.
Does the detector compensate for environmental drift?
Yes. Automatic environmental compensation adjusts smoke sensitivity over the life of the detector, reducing nuisance alarms caused by dust accumulation or environmental changes without manual recalibration.
