Ceiling PIR sensor for home security

The SPT SECURITY 15-951-2 is a wired passive infrared motion detector sold as a 2-pack. It provides 360° floor coverage of up to 22 ft. when mounted on a ceiling up to 7 ft. high. The compact white housing blends into most decors. It suits homeowners adding reliable intrusion detection to small or medium rooms.

Low-voltage operation and silent detection

Each unit runs on a DC 12-Volt supply and draws minimal current during standby and alarm states. Passive infrared sensing produces no audible noise and generates negligible heat. The buffer 72483 design maintains stable performance without active cooling. Wiring is required to connect the sensor to a compatible control panel or power source.

Wired integration for ceiling mounting

Installation requires running low-voltage cables through the ceiling to a security system or power supply. The sensor frees up wall space by mounting flush overhead in the centre of the protected area. It does not suit surface-mounted wiring channels or battery-only configurations. Buyers needing wireless connectivity or outdoor-rated housings should consider other product types.

Questions about this item

How do I wire the 12 V DC connections when mounting the 15-951-2 sensor in a ceiling?

Connect the sensor to a 12 V DC power supply using the supplied wiring terminals; ensure the ceiling height does not exceed 7 ft and position the unit centrally for the full 360° 22 ft floor coverage.

What part of the 15-951-2 will need attention after extended operation?

The passive infrared element and its Fresnel lens should be kept free of dust and cobwebs; gentle cleaning with a dry cloth maintains detection reliability over time.

At what distance does the 15-951-2 stop detecting motion reliably?

The sensor’s specified floor coverage reaches 22 ft at a 7 ft ceiling height; beyond that range detection probability drops off.
