2 Wire Photoelectric Smoke/Heat Detector S10A Comp Id Kidde

The KC2-OSH is a conventional two-wire smoke and heat detector head that pairs Optica photoelectric sensing with a 135°F fixed-temperature/rate-of-rise heat sensor in one low-profile housing. When a job calls for combination smoke-and-heat coverage on a two-wire circuit instead of an addressable loop, the KC2-OSH is the drop-in choice.

Why installers use it

• Built-in drift compensation automatically adjusts sensitivity as the chamber collects dust, meeting NFPA 72 field sensitivity testing without external meters
• Tri-color LED reports alarm (solid red), trouble (flashing yellow), and standby (flashing green) at a glance
• Head-and-base design — order a KC2-SB, KC2-SB4, KC2-RB, or KC2-RB4 base separately to match the box and wiring on the job

Where it fits

Compatible with FX5, FX10, GSA-UM/MAB, RZI16-2, RZI16-2RS, and FX-2WIRE control equipment (UL two-wire compatibility identifier S10A). Specify the KC2-OSH anywhere a two-wire conventional panel needs combined smoke and heat detection at one location.
