Von Duprin Chexit Devices

A Chexit device is very similar to an EL Device, with two main differences:

1] A person exiting must wait 15 seconds (delayed egress)

2] A standard power supply can be used

Quick Tip

You may also add an entry device such as keypad or card reader, but these are not required.

Add On Options

The circuitry inside a Chexit device is very advanced.  Many configurations are possible and can be adjusted in the field.

• Remote Alarm - a separate alarm can we wired into contact within the Chexit device.  The alarm might be located at a nurse's station, for example.
• Nuisance Switch - limits false alarms
• Door Position Input - a door position switch can be wired into contacts
• External Override - entry from the outside can we wired in if using a keypad or card  swiped to gain access.  Access is granted immediately with no 15 second delay.
• Fire Alarm Input - a fire alarm system can be wired in that disables the Chexit delay.

Note: all Chexit devices come with a key switch built in that turns the Chexit feature on or off. It can also be used to reset the system. Also included is a built-in horn that sounds during the 15 second delay period.

Typical Installation

An Alzheimer's area of a nursing home is a common application.  It will require the standard Chexit components shown in the table above, plus two add-on options.

1] An external horn would be mounted near a nurse's station.  This horn will sound once a person has pressed the bar and the 15 second countdown has begun.  Remember, the device has it's own built-in horn, so this second horn would be mounted relatively far from the Chexit device.

2] A keyswitch is also commonly used on the inside of the door.  This allows employees to exit through the door without tripping the alarm.
