STI Exit Stoppers

Put a stop to unauthorised exits and entries through emergency doors.

In a nutshell, the STI Exit Stopper is a compact and clever alarm & magnetic block combination that can be easily fitted to the door and door frame. When the door is opened, the connection between the magnet and the stopper unit is broken, which triggers the alarm. 

Exit Stoppers also feature a key operated override facility to silence the alarm and allow for authorised door use. A best-selling & inexpensive security / nuisance reduction solution - available from stock for next day delivery.
