The Lennox 10B42 D4S & D4P120 single-sensor smoke detector kit is designed for SC/SG120 units and includes 240 units. When smoke is detected, the smoke detector sends a 24VAC signal to the M2 controller, which then affects unit operation based on ECTO settings.
The Lennox 10B42 smoke detector kit provides reliable smoke detection and seamless integration with SC/SG120 units.
