General Description
The model B114LP 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, relay
connections, and an optional RA400Z remote annunciator.
It also includes a resistor that limits current when the asso-
ciated smoke detector is in the alarm state.
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 2. Position the decorative ring around the base
and rotate it in either direction until the ring snaps into
place.
