The Kidde Intelligent Optica KIR-OSD brings advanced photoelectric smoke detection to commercial fire alarm systems running Kidde Intelligent SLC loops. Rotary addressing keeps commissioning simple and field-serviceable - set the address with a screwdriver, no laptop or programming tool needed. Automatic environmental compensation keeps sensitivity thresholds accurate as the chamber ages, reducing nuisance alarms and service calls over the life of the detector.

Built for the fire alarm installer

The Optica series is Kidde's current-generation intelligent detector platform, listed to UL 268-7, UL 268A, CAN/ULC-S529, and CSFM. SLC loop powered at 15.20-19.95 VDC with a standby current of just 43 µA, so it won't tax existing loop power budgets. Mounts on any standard Kidde Intelligent detector base - standard, relay, isolator, or sounder - with a twist-lock connection consistent across the Optica and legacy Intelligent lines. High-impact engineering polymer construction in white matches the rest of the Kidde detector family.

Key features

  • Advanced photoelectric sensing: optimized chamber design reduces nuisance alarms while maintaining reliable response to visible-particle smoke
  • Rotary addressing: field-set address with a screwdriver, no software or laptop required
  • Automatic drift compensation: self-adjusting sensitivity keeps the detector accurate over its service life without manual recalibration
  • CleanMe LED indicator: visible maintenance alert when the chamber needs cleaning, cutting unnecessary truck rolls
  • 360° visible LEDs: twin indicators visible from any direction for walk-test and status verification
  • Flexible base options: standard, relay, isolator, and sounder bases support a wide range of installation requirements

System requirements

Connects to any Kidde Intelligent fire alarm control panel via two-wire SLC loop. Requires a compatible Kidde Intelligent detector base (sold separately). Bases accept #18 AWG to #12 AWG wire with a maximum resistance of 10 ohms per wire. Compatible detector testers: Testifire 1000 and Testifire 2000.

FAQs

What bases are compatible with the KIR-OSD?
Standard (KI-SB/KI-SB4), relay (KI-RB/KI-RB4), isolator (KI-IB/KI-IB4), and sounder bases (KI-ABST, KI-ABLT, KI-ABDT). Also supports the GSA-LED Remote Alarm LED on standard bases.
What fire alarm panels does this work with?
The KIR-OSD connects to any Kidde Intelligent fire alarm control panel via two-wire SLC loop. Part of the Optica series, Kidde's current-generation intelligent detector platform.
How do you set the address on the KIR-OSD?
Set the address at the detector using the rotary switch and a screwdriver. No laptop, software, or programming tool needed. Field changes are just as easy during service.
Does the KIR-OSD have drift compensation?
Yes. Automatic environmental compensation adjusts sensitivity as the chamber ages or accumulates debris, reducing nuisance alarms and extending reliable service life without manual recalibration.
Does the KIR-OSD support sounder bases?
Yes. Three options: KI-ABST (fire), KI-ABLT (low-frequency for CO/fire), and KI-ABDT (standard-frequency for CO/fire). All sounder bases require 24 VDC from the FACP.
What detector testers work with this detector?
Compatible with the Testifire 1000 and Testifire 2000 for functional smoke testing during commissioning and maintenance.
