GENERAL DESCRIPTION
The B616LP plug-in detector base is used with Notifier model CP-651, CP-651A, and CP-651E ionization detector
heads and SD-651, SD-651A, and SD-651E photoelectronic detector heads. The capability of plugging these detectors
into a variety of special bases makes them more versatile than equivalent direct-wired models.
The B616LP base is intended for use in 2-wire systems, with screw terminals provided for power and relay contact con-
nections. These bases MUST be current limited by the system control panel in the alarm state.
