PRODUCT OVERVIEW

Multipurpose lockable cabinets for remote annunciators, fire alarm control panels or
other electronic products which require physical or environmental protection. Helps
guard against vandalism (accidental or intentional), as well as dirt, dust and grime
(models without alarm). Covers mount on the wall enabling the unit to be stored in a
central location. The cabinets are available with a key or thumb lock, with or without
siren alarm or siren/strobe alarm. They also have an additional eyelet for a secondary
lock or safety seal.

HOW THEY WORK

Cabinets are constructed of a clear polycarbonate which allows the unit within to be
highly visible and accessible. When cabinet with siren alarm is opened, the alarm emits
an ear piercing siren (model with siren/strobe alarm also flashes), drawing immediate
attention to the area. Operator has to unlock the unit and open the lid for access.
