General Description
The Model B112LP detector base is designed for use with
System Sensor model 2151 photoelectronic and 1151 ioniza-
tion detector heads. This four-wire base is equipped with
screw terminals for the connection of power, ground, and
an optional remote annunciator.
Mounting
The detector base mounts directly to 3-1/2 inch and 4-inch
octagon boxes and 4-inch square boxes, with or without
plaster rings. To mount the base, remove the decorative
ring by rotating it in either direction to unhook the snaps
before separating the ring from the base. Use the screws
supplied with the junction box to attach the base to the
box through the appropriate slots in the base (see Figure
1). Position the decorative ring around the base and rotate
it in either direction until the ring snaps into place.
