STI Resettable Break Glass Unit (Flush, Double Pole, Green)

STI Resettable Break Glass Unit: Overview

When someone smashes the glass of a traditional break glass unit, it needs replacing before it works again. While replacing them isn't too expensive, it's a cost that adds up over time. And if you don't have any replacements on hand, your emergency door release is off-limits until a replacement is ordered and arrives.

This emergency break glass unit uses a patented mechanism that doesn't need to be replaced; instead of glass, it's a rigid plastic element combined with an over-centre spring that gives the same real "give" and resistance as breaking glass, without any actual glass to shatter, clean up, or replace. Press it, and an activation indicator flag drops into view to confirm it's been triggered. Reset it with the supplied key, and it's ready to use again immediately, no waiting for a maintenance team to fit a new pane.

This unit uses a double pole changeover switch, meaning it can control two separate circuits from a single press, releasing a door lock and triggering an alarm at the same time, for example, or operating two separate lock connections.

Access Control Done Correctly

We take access control seriously and that means that we take who can exit your building as seriously as who can enter it. An emergency exit button is a non-negotiable in any building that is using access control, but there's no need for these devices to add additional costs over time. By using the reset key supplied, this unit can be reset again and again, protecting your staff from being trapped in the building in an emergency yet keeping your security protocols intact.

Because there's no real glass involved, this is a good fit for schools, care settings, and any public building where false activations happen regularly, as they prevent additional spend and unneeded downtime.

This unit is flush-mounted; if you need a surface-mounted version instead, we also stock the STI Resettable Break Glass Unit.
