Gizmo Engineering - Model SA-3 - Siren Alarm Box Annunciator

The Siren Alarm Box generates a painfully loud 115 dB 2feet. The loudest 12VDC buzzer in existence. Combined with a strobing beacon LED, alarms cannot be missed.

Gizmo Engineering - Custom Alarm Boxes

This battery powered tilt switch alarm is mounted on a horizontal PVC pipe (used as a low height crash bar) meant to protect against forklifts running into a low hanging wall . If the crash bar pipe is bumped by a forklift, the alarm sounds for 10 seconds. (this time is selectable) Since the tilt switch alarm its mounted out-of-reach, battery replacement is inconvenient, and so we used a very low power circuit that allows the battery last for 10 years. (quiescent current is only 2µA !)

Gizmo Engineering - Model AB-HB - Height Bar Alarm

Height clearance bar alarm quickly mounts on most existing height clearance bars with a thumbscrew. It is activated by a strike from a vehicle for example. A loud warbling buzzer sounds for 10 seconds, accompanied by a flashing LED.
