1. Surface Mounting and Wiring Instruction
a. The unit is to be mounted using four 3/8" (M10) bolts
(not supplied) into the base enclosure.
b. Remove the enclosure cover by loosening the twelve
M8 stainless steel cover screws.
c. The cover is fixed to the enclosure with a bonding
wire. Bonding wire will keep the cover attached and provide strain-
relief for the internal wiring during installation.
d. The unit is provided with three conduit/cable entranc-
es for field wiring. Entries may be used for connection of data/power
from the Central Control, external loudspeaker connections, or relay
output connection. Note: The internal grounding terminal shall be
used as the grounding equipment means and that the external terminal
is only a supplemental bonding connection where local authorities
permit or require such a connection.
