GENERAL DESCRIPTION The model B114LP detector base is designed for use with System Sensor model 2151 photoelectronic and 1151 ionization detector heads. This four-wire base is equipped with screw terminals for the connection of power, ground, relay connections, and an optional RA400Z/RA100Z remote annunciator. It also includes a resistor that limits current when the associated smoke detector is in the alarm state.
