Product Overview
These virtually indestructible covers (slotted for horn or speaker units and solid for
strobe-only alarms) are designed to stop vandalism and accidental damage. Molded
of clear, thick, UV-stabilized polycarbonate material, they are backed by a three year
guarantee against breakage in normal use. Slots in the STI-1210, 1215, 1217 and 1219
allow the horn to be heard. The STI-1221, 1225, 1227 and 1229 are for strobes only.
Many tough, clear spacers are available for larger strobe/horn units, retrofits, surface-
mount and weather resistant applications. For the STI-1210/1221 series, spacer A has
a four inch deep enclosed backbox, spacer B has an enclosed backbox molded with
an integral double-gang outlet box. Spacer C has an open back for retrofit applications.
Spacer D accommodates deeper units and applications with exposed conduit electrical
connections. Spacer E has an open back frame for flush-mount applications. An
appliance mounting plate comes with the STI-1219/1229. Unique Enviro Kits are
available for extreme conditions where dampness or water is present.
