CP1100 Overfill Protection Device Indoor Alarm
Model AL101-D-R-T Indoor Alarm

The Model AL101-D-R-T is an indoor alarm that controls a combustion air damper. The Damper is normally open and powered closed by this panel. When the generator starts, the power is cut and the damper opens. The white pilot light indicates the 120 VAC power. The red pilot lights provide the visual alarm indication for the damper failure. When the generator starts it supplies a dry contact to the panel which activates the timer. In 15 seconds, if the damper does not open, an audible alarm and a red pilot light will indicate the damper did not open. The damper test button simulates the generator starting and will open the damper (If the damper does not open the alarm will sound showing the damper did not open). To test the damper contact is closed when the damper is powered, push the test damper failure button, if the light and horn turn on this means the contact is closed. The mute push-button is a momentary switch that mutes the horn. The damper alarm has a corresponding relay output contact.
