STI Horn/Strobe Damage Stoppers
®
STI-1221E
PRODUCT OVERVIEW
This virtually indestructible cover (slotted for sounder/strobe unit) is specifically
designed to prevent vandalism and accidental damage to a signal unit of a fire alarm
system. Moulded in clear, thick UV-stabilised polycarbonate material with slots
allowing the sounder or fire voice speaker to be heard. There are a variety of spacers
available to accommodate larger sounder/strobe units and retrofits - as well as
weather resistance and surface mounted applications. Spacer B has a solid back and
is moulded with an integral mounting box. For extreme conditions where dampness,
water or dust are frequently present, we recommend using STI’s unique, new Enviro
Kit.
HOW IT WORKS
Both the cover and circular back box are moulded from clear, thick polycarbonate
material that is UV-stabilized against discolouration. It is backed by a three year
guarantee against breakage in normal use.
