When the alarm is activated, you want to know it is for real, you want staff to take notice, and you want to keep down-time to a minimum.
This is sometimes easier said than done, especially when your construction area traverses a public pedestrian zone, or site workers make a habit of trying to close early for the weekend. It may even be something as simple as passing materials knocking against the switch gear, but any of these scenarios can result in false alarms, and ultimately wasted time.
The Howler Alarmed Switch Cover is manufactured from tough Perspex, with an integral high-pitched siren that sounds as soon as the cover is lifted, deterring persons from playing with the alarms. The cover can be tamper-tagged with frangible tags to provide even more security.
