C-TEC are now official distributors of STI's Range of Manual Call Point covers which includes their Euro Stopper (pictured left), Universal Stopper and standard Call Point Stopper.
The latest revision of BS 5839-1 (2017 section 20.2b) states "All MCPs should be fitted with a protective cover, which is moved to gain access to the frangible elements".
This means all call points in vulnerable areas should now be protected with a cover without the need to consult the site's fire safety officers. The STI Range allows you to do this.
