Kidde 20SAR Smoke Detector Ac Dc Round

Product Description

The KIDDE 20SAR is a round-profile smoke detector designed for AC/DC power operation in aspiration-based smoke detection systems. Built for single-unit installation, it supports both hardwired AC and DC power inputs, making it adaptable to a range of residential and light commercial fire detection configurations. Licensed electricians and fire alarm system technicians are the primary installers of this device. The round form factor fits standard electrical box footprints, and the unit ships individually for straightforward single-zone or supplemental detector installations.

The 20SAR is suited for aspiration smoke detection applications where early warning sensitivity and dual-power compatibility are priorities. It fits into systems where detectors must maintain operation during primary power interruptions by switching to DC backup. Typical install scenarios include commercial corridors, server rooms, or residential retrofits where code requires interconnected or battery-backed detection coverage.

Key Features

• Dual AC/DC power input supports hardwired operation with battery backup capability
• Round profile fits standard electrical box cutouts for simplified mounting
• Designed for aspiration smoke detection system integration
• Single-unit packaging supports individual zone or replacement installs

Compatibility

Designed as an OEM-style replacement or new-install detector for aspiration smoke detection systems requiring AC/DC round-format smoke detectors.

Installation Notes

Installation should be performed by a licensed electrician or certified fire alarm technician in accordance with NFPA 72 and applicable local codes. Shut off power at the circuit breaker before wiring the detector to any AC circuit. Do not bypass the ground wire or defeat the interconnect wiring where required by code. Verify detector placement heights and spacing per NFPA 72 guidelines before finalizing installation.
