The Von Duprin Chexit device is designed for accident hazard or fire exit applications. It meets both life
safety and security needs as well as all requirements of NFPA101®for “Special Locking Arrangement” and
UBC “Special Egress-Control Devices.”
The Von Duprin Chexit device sounds an alarm and keeps an exit door secured for 15 seconds following
an attempt to exit. The Chexit releases immediately upon a fire alarm condition.

Complete the items on the checklist below before installing the Chexit module. Each component listed
should be prepared and installed according to the installation instructions supplied with it.
Mechanical Preparation
1. Door and frame have been prepared for power transfer.
2. Chexit device has been installed. (See instructions packaged with Chexit device.)
3. Trim such as a lever handle, if used, has been installed.
4. Suggested: Obtain a 1 1/4” mortise cylinder. (It is easier to install the mortise cylinder
during electrical installation than after electrical installation.)
Electrical Preparation
1. Read all of these instructions before installing the Chexit module.
2. If available, get a wiring diagram for your installation. Otherwise, refer to Figures 2, 3, 5, 7 and
Table 1 in “Typical Wiring” and mark the components you use in Table 1.
3. Determine the physical location of each component used (see Figure 1, 4, and 6).
4. Pull field wiring between component locations and frame side of power transfer (see Figure 1, 4,
and 6).
5. Mount components and connect them to field wiring (see Figure 2, 3, 5, or 7).
6. Connect field wiring to frame side of power transfer. (Route wires through frame back box.)
7. Install frame back box and frame side of power transfer.
8. Get requirements for Chexit option switches, record in Table 3 in “Options,” and set switches.
9. Complete steps 1 through 9 of “Installation.”
To install mortise cylinder after electrical installation:
1. Remove end cap and end cap bracket (see “Installation” step No. 1).
2. Slide cover plate out until knurled ring is visible; install cylinder (see “Installation” step No. 4).
3. Complete steps No. 4, 6, 7, and 9 of “Installation.”
Components must be connected to
wire colors as shown in Figures 2, 3,
5, and 7 in “Typical Wiring.”
IMPORTANT
!
The wiring requirements in Table 2 in
“Typical Wiring” must be followed.

In this double door application, both doors open in the same direction and each is equipped with a Chexit. The two Chexits are
connected (ganged) by the gray (CM+) and violet (CM-) wires. (If not used, insulate these wires separately.) When one
Chexit is set into alarm, the other also goes into alarm, and both unlock after 15 seconds. A fire alarm unlocks both doors at
the same time. An external inhibit device also unlocks both doors at the same time. After an external inhibit, the door that
was used rearms 2 seconds after closing, and the unused door rearms after the full rearm time. For proper operation, the
rearm times of ganged Chexits must differ by at least 2 seconds.

OPERATION
The operation of a Chexit with a door position switch is the same as described in the summary table, but:
sThe Chexit enters Armed mode 2.5 seconds after the door position switch contacts close.
sIf the door is held open and rearm time expires, the Chexit goes into Alarm mode.
sWhen in Armed mode, the Chexit goes into Alarm mode if the door position switch contacts open.
The basic function of a Chexit is to sound an alarm and keep an exit door secured for 15 seconds following
an attempt to exit. Test the operation of your Chexit by performing actions No. 1 through 6 in the summary
below. Make sure your Chexit matches the descriptions in the summary. If it does not, see “Troubleshooting.”
TROUBLESHOOTING
Turn Chexit off, then back on, using key switch. Compare Chexit operation with the following table to
identify problems and solutions. After troubleshooting, re-test Chexit using steps under “Operation.”
Symptom
Red LED flashes fast and
horn sounds
Problem
Fire alarm contacts open
1. External inhibit contacts open
2. External inhibit function not used
and wires not terminated properly
Red LED flashes once
Solution
Connect normally closed fire alarm contacts
between yellow and white wires
1. Connect normally closed external inhibit
contacts between green and white wires
2. If external inhibit not used, connect green and
white wires together
Red LED does not light Power not reaching Chexit Replace/reset AC fuse/circuit breaker;
check power supply input/output voltages;
check input voltage at Chexit cable connector
Red LED on solid then flashes fast
and horn sounds
1. Pushpad pressed
2. Pushpad switch disconnected
1. Release the pushpad
2. Connect pushpad switch connectors (see step
No. 6 of “Installation”)
Red LED on solid then flashes
fast, horn sounds, and solenoid
pulls in for one second (two
sharp sounds)
1. Door open
2. Door position switch contacts
open
3. Door position function not used
and wires not terminated properly
1. Close door
2. Connect normally closed door position switch
contacts between orange and white wires
3. If door position switch not used, connect
orange and white wires together
Action
1. Turn on Chexit with key switch

Rearm Time Notes
1. Set the rearm time a few seconds longer than
the door will be open so the door closes before
the Chexit arms.
2. The Chexit is shipped from the factory with the
rearm time set to 10 seconds.
3. When the rearm time is infinite, the Chexit
arms when the door position switch detects
that the door is closed.
4. When the rearm time is infinite, you must open
and close the door after the Chexit is turned on.
5. If a door position switch is used, the Chexit
arms 2.5 seconds after the door closes.
6. If you are using a door position switch but you
want the full rearm time to expire before the
Chexit arms, call Technical Support at
1-877-671-7011.
7. For proper operation, the rearm time of each
ganged Chexit must differ by at least 2 seconds.
