The Federal Signal PMC-048-240G is a panel mount multi-functional audible and visual signal designed for voltage ranges between 48-240V, featuring a green LED. This model incorporates multichannel technology enabling three distinct alarm levels—alert, pre-alarm, and alarm—each controllable via independent electric contacts. It supports three independent electrical channels: a flashing light on channel 1, an intermittent sound combined with flashing light on channel 2, and a steady light with continuous sound on channel 3. The device is equipped with a self-extinguishing PC body that offers protection against vibrations, dust, and atmospheric elements and is designed for panel mounting using a 1.18" hole secured with a locking ring.
