The KI-OSHD combines an optical smoke sensor with a 135°F fixed-temperature, 15°F/min rate-of-rise heat sensor in a single intelligent detector head, cutting the alarm-verification guesswork that comes with single-criteria devices.

Built for the commercial fire installer

Twist-and-lock mounting drops installation and service time on every job, and the detector runs on Kidde's standard intelligent bases — standard, relay, isolator, or audible — so one base stock covers the whole job. A bright dual-color LED flashes red in alarm for at-a-glance status from the ground, and on-board self-diagnostics flag a dirty optical chamber before it becomes a nuisance-alarm callback.

Key features

  • Multi-criteria optical + heat sensing reduces false alarms versus single-sensor detectors
  • 135°F fixed temp with 15°F/min rate-of-rise heat element
  • Field-replaceable optical chamber — no truck roll for a full detector swap
  • Twist-and-lock base mounting with optional tamper-resistant lockdown
  • Automatic drift compensation and dirty-sensor warning cut false-alarm callbacks
  • UL/ULC/CSFM listed

Compatibility

Mounts to Kidde standard, relay, isolator, or audible intelligent detector bases on standard North American two-gang or 4-inch square electrical boxes.

FAQs

What does "multi-criteria" mean on the KI-OSHD?
It combines an optical smoke sensor and a heat sensor in one head, using both readings to confirm an alarm condition and reduce nuisance false alarms.
What heat threshold does the KI-OSHD use?
A 135F fixed-temperature element with a 15F-per-minute rate-of-rise function.
What bases is the KI-OSHD compatible with?
Kidde standard, relay, isolator, and audible intelligent detector bases.
Is the optical chamber field-replaceable?
Yes, the optical sensing chamber can be replaced in the field without swapping the entire detector head.
