STI Ranges We Stock

Choosing an STI Cover

Match the mounting to the call point: flush covers for flush call points, surface covers with a spacer for surface back boxes. Sounder models give a local alarm when the cover is lifted, which deters malicious use. For outdoor or damp areas choose Weather Stopper II or Enviro Stopper. Check the cover dimensions against your call point before ordering.

STI Stopper FAQs

What is an STI Stopper?

A hinged polycarbonate cover from Safety Technology International that fits over a manual call point to help prevent accidental or malicious activation while leaving it usable in an emergency.

Does a call point cover stop the call point working?

No. The cover lifts to give access to the call point. Agree cover use with whoever is responsible for the fire alarm system.

How loud is the Exit Stopper?

The STI-6400 gives a 95/105 dB alarm and runs on a 9V battery, with a 12/24VDC connection option.
