CXTheChexit

Door position input: An external door position switch can be

connected to the Chexit.

Using the door position input ensures that the door is in the

closed and latched position before the device rearms.

External inhibit input: This optional input is provided to allow

authorized egress of the Chexit in the armed condition. It also

allows remote reset of the Chexit in an alarmed condition.

Fire alarm input: This input disables the Chexit immediately

upon a ﬁre alarm.

Internal auxiliary lock: The Auxiliary Lock is engaged when the

Chexit is armed. The locking mechanism is speciﬁcally designed

to hold securely even when the exit device is struck with forceful

blows.

User deﬁneable rearm time: The Rearm time is the amount of

time aer the device is activated before it arms. It is designed to

give someone time to pass through the door before rearming

oocurs. Timing can be changed by the user for any time between

2 and 28 seconds in two second increments. There is also an

inﬁnite rearm setting that requires the use of an external door

position switch. In this setting the door remains in the rearm

mode until the door is closed. This can be useful on jet way doors

in an airport.

Factory deﬁneable delay time: Most jurisdictions allow 15

seconds of delay before allowing egress. In those cases where 15

seconds is not appropriate, Von Duprin can set the Chexit for any

delay time between 0 and 60 seconds on 2 second increments.

For delays greater than 15 seconds a letter from the local

authority is required.

Chexit typical application

Chexit single door with options – The Chexit is used as an

access control device. The card reader allows access. Also

shown in this application is an external horn and door position

switch. The auxiliary horn is used for increased volume in

remote locations. Using a door position switch gives added

security to the opening in case the door is not reclosed.

With the Chexit disarmed, the opening functions as a normal

exit device. If card readers are required on both sides of the

door, the normally closed contacts of the readers should be

weird in series.

Designed for use on delayed exit applications, the Chexit system is

ideal for controlled areas.

All controls, auxiliary locking, local alarm, and remote signalling are

self-contained in the Chexit, providing safe, secure, easy to install

and simple to operate door control and exit hardware.

Chexit controlled exit device for use on panic or ﬁre exit hardware

applications.

This concept in delayed exit systems combines life safety with the

needs of security and meets all requirements of NFPA 101 for

“special locking arrangement.”

The Chexit device includes a 6" x 20" decal for application on door.

“PUSH UNTIL ALARM SOUNDS.

DOOR CAN BE OPENED IN 15 SECONDS”

Minimum width door opening:

§ 3' Device 34" opening

§ 4' Device 40" opening

Consult factory for other size requirements.

Solenoid speciﬁcations:

§ Continuous duty – 24VDC

§ Current inrush – 16 amperes

§ Current holding – .3 amperes

Requires PS914 Power Supply

Request to exit switch: Built into the device to detect when

someone attempts to exit. Pushing the push pad when the device

is armed will cause this switch to start an irreversible alarm cycle.

Nuisance alarm: When a Chexit is located in a public area, it can be

desireable to limit false alarms. If the Nuisance Delay options are

set to off, the device will go into alarm as soon as the push pad is

touched (when armed). Turning the Nuisance Delay on will require

the push pad to be pressed for 1 second before the Chexit goes into

alarm. If the Nuisance Audible and Nuisance Delay are both on, the

alarm will sound as soon as the push pad is pressed, but the alarm

sequence will stop unless the push pad is held for 1 second or more.

Remote alarm: A relay contact is provided to give external alarm

indication. This contact close when the device is in an irreversible

alarm condition. This contact can be used to drive a horn, lamp, or

other indicative device.

Key switch: The Key switch provides the means to arm, disarm or

reset the Chexit. The key can be removed in either the Arm or

Disarm position.

Indicator lamp: The status of the Chexit can be determined by the

indicator lamp. When the lamp is off, this indicates the device is

disarmed and is functioning as a normal exit device (no delay). A

continuously on lamp indicates the device has just been armed and

as soon as the selectable rearm timer expires, the device will arm.

A slow ﬂashing lamp indicates the device is armed. A fast ﬂashing

indicator lamp indicates the device is in alarm.

Internal horn: Whenever the device is in alarm or the push pad is

pressed the internal horn will sound. The volume level of this horn

exceeds 85 db at 6 feet.
