This Tamper-Resistant Substation has an extremely rugged metal front plate of anodized, brushed aluminium. The substation has a unique design to protect the loudspeaker, microphone, LED indicator and internal electronics from external abuse. The station flush-mounts on a back box. The metal front plate can be securely fastened to the box with 4mm tamper resistant screws (provided) or pop rivets.
Fast call initiation is possible with the call-in button.
