Silent Knight SD505-AHS Heat Detector - Used, Fully Functional

Here's a used but fully functional Silent Knight SD505-AHS heat detector.

It's been previously installed but is in good working order.

It may have some minor cosmetic signs of wear, but it's ready to do its job.

This is a standard component for Silent Knight fire alarm systems.

A great option if you need a spare for testing or to replace a faulty unit on a budget.
