The detector used with this base should be cleaned at least once a year. General Description The B406B plug-in detector base is used with a variety of System Sensor conventional detector heads. They are capa- ble of accepting a variety of detector heads, which makes them more versatile than equivalent direct-wired models. Refer to the System Sensor catalog for other available plug- in detector bases. The B406B 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 sys- tem control panel in the alarm state.
