The Hochiki HPS-CP series is very dependable break glass station intended for simple yet failsafe operation. The actuating switch is a heavy duty plunger type, with a Glass plate covering (2.5 x 2.5) which is a Factrolite single strength (obscured) type. Design of this station is such that it seems to inhibit the “false alarm” factor that is so prevalent in public schools and places of public assembly.
