Dortronics' 7281-EA Door Prop and Exit Alarm

Dortronics is offering a new door prop and exit alarm. This versatile unit can activate a local alarm with the built-in sounder and signal an independent system with a relay output if the door has not been closed within the allotted time. As an alarm timer, it can also be configured to monitor emergency exit doors to provide an immediate alarm whenever the door is opened, even if the door is immediately re-closed. Featuring a unique design to protect the timing circuit against voltage spikes and surges, the #7281-EA units will operate on 12 or 24 volts DC, requiring only 0.05 amps. There is also an adjustable time delay period and automatic or manual alarm reset. Available in brushed stainless steel or beige painted finish.
