General Description
The Model B112LPA detector base is designed for use with
System Sensor model 2151A photoelectronic and 1151A
ionization 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.
