Surface-Mount Audible/Strobe Guard

The STI-9720 is a surface-mounted guard constructed from 9-gauge coated steel wire in white. It protects compatible system sensors indoors or outdoors while allowing the audible alarm and strobe to remain fully visible and audible.

Verify sensor fit and mounting surface

Confirm the sensor you intend to protect matches the guard’s open-back design and surface-mount profile. The operating temperature range spans -40 to 250 degrees F, so ensure the installation environment stays within those limits before ordering.

Integrates with existing system sensors

The guard installs directly over the sensor using the included mounting hardware, requiring no modification to the sensor itself. It adds a physical barrier without blocking sound or light output, preserving the sensor’s original coverage pattern.
