System Sensor B401B is a plug-in detector base compatible with System Sensor smoke detectors: 1451, 2451, and 2451TH. It allows for easy installation and maintenance of smoke detectors, making them more versatile than equivalent direct-wired models. The B401B is designed for use in 2-wire systems and features screw terminals for power, ground, and remote annunciator connections. It has a standby rating of 120µA maximum and an alarm rating of 4.2 VDC minimum at 10 mA and 6.6 VDC maximum at 100 mA.
