Details: Dortronics 7281 Series Local Door Exit Alarm

Low Cost Door Prop Alarm

The Dortronics 7281-EA door alarm can be configured to provide an audible alert, at the door, if it is not closed within a specified time. If the door is held open past the allowed time, the piezo alert is sounded until the door is closed or the alarm is reset.

Exit Alarm on Door Opening

The 7281-EA can also be configured to provide an immediate alarm on door opening. The alarm can be timed to automatically silence or "latched" on until manually reset.

Adjustable Timed Delay

The "door open" time, for the door prop operation and the "automatic reset" time period, for the exit alarm, is field adjustable. This time delay can be set from 2 to 60 seconds.

Automatic or Manual Alarm Reset

The alarm sounder can be configured to reset automatically or require a manual reset by key to be silenced. When used as a door prop the alarm is automatically reset on door close. If used as an exit alarm the automatic reset can be by door closure after a time delay. Either operation may utilize a manual reset by key switch, digital keypad, or other momentary switch.

LED Indicator

A tri-state LED is provided for visual status of the door alarm. When the door is secure the LED is green, amber during door unlock/shunt, flashing amber when door is open (authorized), flashing red during the warning period, and the LED is steady red while in alarm.

Optional R-E-X Button

A push button can be supplied on a double gang plate to provide a request-to-exit signal to the card access system. This momentary dry contact output is totally independent of the alarm electronics.

Optional Key Reset/Shunt Switch

An optional key switch is offered to allow a manual reset by key. This key switch can also be used to provide an alarm shunt function.

Compact Mounting Styles

The Dortronics EA door alarm modules are supplied on a single gang plate for prop alarm with sounder and LED. If the optional mushroom pushbutton or key switch is used a double gang plate is required.
