Q: Chexit goes into alarm with fast flashing LED and not locking after rearm time.
A: Chexit devices shipped after 8-24-2015 with motor driven:
Module DPS LED is ON
DPS switch contact is open: Close the door, if open. Verify the DPS contacts are closed when the door is closed.
DPS wiring/connection is open. With door closed, verify the DPS wiring has continuity from DPS contacts to module.
Module REX (Request Exit) LED is ON.
REX Cable is disconnected (plug in the cable).
REX switch is defective (replace REX switch assembly).
Defective Shock Absorber in the device may not allow the push bar to extend all the way out causes the REX switch contact not to close. Remove the Shock Absorber and test the device.
Module Block LED and motor status LED are OFF
Blocking Device Cable to the motor is disconnected (Plug in the cable).
Blocking Device Cable has broken wire (replace the cable).
Chexit motor assembly is defective. Call Customer Service 877-671-7011 to replace the device.
Rim and vertical rod device, the latch bolt can't extend. Make necessary mechanical adjustment to latch properly.
Push Pad is held in. Verify Push Pad is extending fully.
Chexit devices shipped prior to 8-24-2015 with solenoid driven:
Chexit device has a RX switch with a connector that needs to be connected to the Chexit module otherwise the alarm will sound after the rearm time.
RX switch must have a closed contact to operate the device properly. If the contact is open (switch is out of adjustment or defective switch) Chexit will go into alarm after the rearm time.
Defective shock absorber in the Chexit device may not allow the pushbar to extend all the way out causes the RX switch contact not to close. Remove the shock absorber and test the device without it.
If DPS (door position switch) switch is used with the Chexit device, the normally closed contact of the DPS must be connected to the ten wire connector cable of the Chexit between orange and white or orange and red wires. If the contact of the DPS is open Chexit will go into alarm after the rearm time.
If DPS is not used with the Chexit device, make sure orange wire is connected to the white wire.

Part number for Von Duprin standard 15 sec. release Chexit module shipped prior to 8-24-2015 with solenoid driven is 050228-00.
Q: What cylinder is required to for the Chexit device?
A: For Chexit devices shipped after 8-24-2015 with motor driven:
The Chexit device will use a 1 1/4" mortise cylinder with straight cam. Schlage cylinder 20-001-114 recommended.
CAUTION: The length of the cylinder from bottom of the security collar to the bottom of the cam must be no more than 1 1/16". Refer to page 9 step 7j of the installation instructions for more information.
Q: Why does a Chexit device blink once then powers down?
A: If Chexit device LED blink once when you turn the unit on, the External inhibit green wire is not by passed or not connected to the access control normally closed contact.
For devices shipped after 8-24-2015 with motor driven connect the green wire to the red wire of the twelve field wire connector cable of the Chexit device if you are not using the access control option. If access control is used connect the normally closed access control contact between green and red of the same cable.
For devices shipped prior to 8-24-2015 with solenoid driven connect the green wire to the white wire of the ten wire connector cable of the Chexit device if you are not using the access control option. If access control is used connect the normally closed access control contact between green and white or green and red of the same cable.
Q: Will CX re-arm if door is held open?
A: A Chexit device could arm when the door is open but door may not close to secure the door unless a Door Position Switch (DPS) is connected to the device then the device goes into alarm after rearm time if door is in open position. If the door is going to be propped open for long periods of time, the device should be turned off or external inhibit controller should be activated for periods of time or set the rearm time for infinite rearm. DPS is required for infinite rearm function.
Q: Can the NL key override be used on Chexit Rim or Vertical Rod devices?
A: The NL key override will not open the door while Chexit rim or vertical rod device is in the arm mode.
Q: Will a Von Duprin Chexit device automatically rearm itself after a fire alarm clears?
A: The Von Duprin Chexit device will not automatically rearm itself after a fire alarm clears. After a Fire Alarm has triggered the Von Duprin Chexit device, the device must be manually reset through the key in the CX device or through access control system.
Q: Is a fire alarm board required for a Chexit using the PS914?
A: Fire alarm contact would tie right into the Von Duprin Chexit device not to the PS914 power supply. There is no requirement to install the fire alarm board.
Q: Can you connect an external horn to a Chexit device?
A: Chexit devices shipped after 8-24-2015 with motor driven:
Use the Alarm Relay Contacts on Field Wiring Cable, blue and brown wires of the Chexit device.
Connect the blue wire to +24VDC (red wire on Field Wiring Cable) and connect the brown wire to positive side of the horn and negative side of the horn to ground (black wire on Field Wiring Cable)
Chexit devices shipped prior to 8-24-2015 with solenoid driven:
Use the external alarm contact, blue and brown wire on Chexit device.
Connect the blue wire to the red wire and connect the brown wire to positive side of the horn and negative side of the horn to ground (black wire). Q: How many transfer wires are required for a Chexit device?
A: Depends on which options are used on the Chexit device. Most application use 6-8 wires, but can use up to ten wires.
Q: The 15 second crashbar hold has stopped working. Should the pre 8-24-2015 module be replaced
A: Naturally it would only be replaced if it has stopped working meaning there's nothing about the age inherently that would require it to be maintained or replaced on a maintenance schedule such as a consumable product like a fire safety agent it is to be replaced even though the system hasn't been actuated on a regular maintenance schedule along with fusible link.
Q: What would cause my Chexit to go into a weak alarm 10 seconds after arming it?
A: The following could cause the Chexit device shipped prior to 8-24-2015 with solenoid driven to go into weak alarm with solid LED light:
Wrong power supply- Chexit device requires a PS873 or PS914 power supply without any option board.
Wrong gauge wire-
100 ft use #14 gauge wire
200 ft use #12 gauge wire
Wrong fuse in the PS873 power supply, requires 4 Amp slow blow fuse.
Defective Chexit module. Check the voltage between green and yellow wires that connects to the solenoid and make sure there is no voltage measures when Chexit module goes into the arm mode. Q: What would cause the Von Duprin Chexit device to have one red flash when armed then nothing?
A: Chexit devices shipped prior to 8-24-2015 with solenoid driven.
The GREEN wire is not shorted to the WHITE if no Access Control system is used.
If Access Control system is used, then you must use NC Dry contact between WHITE (or RED) and GREEN wires.
The WHITE wire is not providing 24VDC voltage when CX device is armed which means the CX module is bad.
If Access control contact going to the Chexit device stays open, it will causes the Chexit device to flash once upon arming. Make sure normally closed contacts from access control system connected to the GREEN and WHITE or GREEN and RED wires of the Chexit device.
Chexit devices shipped after 8-24-2015 with motor driven.
The Green wire is not shoeted to the Red wire if no Access Control system is used.
If Access Control is used, then you must use NC dry contact between RED and GREEN wires.
If Access control contact going to Chexit device stays open, this will cause the Chexit device to flash once upon arming.
Make sure normally closed contacts from access control system connected to the GRREN and RED wires of the Chexit device. Q: Is there an external horn for use with the Chexit device?
A: chlage Electronics 1910 series horn as seen here:
Click Here
can be used as an external horn with Von Duprin Chexit device.
Q: Is the Von Duprin Chexit, RCM, and DE5300 circuit board the same for all these functions?
A: Yes, standard 15 second release board will work for the Chexit, RCM, and DE5300 (for the 15 second release period).
Q: CX will not arm. Red light on solid waits 10 sec, light goes out and cycle repeats
A: Inadequate power or wrong gauge wire is used. The inrush current demand by CX will overload and shutdown the power supply if undersized. You must use the Von Duprin PS873 or newer PS914 supply.
Q: How do I connect External Inhibit wires on Chexit?
A: Chexit devices shipped prior to 8-24-2015 were solenoid driven: A normally closed card reader contact, key pad contact or any other control contact connects to the Green and White wires of Chexit cable otherwise the device remains disarmed.
Chexit devices shipped after 8-24-2015 are motor driven: A normally closed card reader contact, key pad contact or any other control contact connects to the Green and Red wires of the Chexit Field wiring cable.

Q: Why is my Von Duprin Chexit device not lighting up or arming?
A: Devices were shipped from the factory with motor driven after 8-24-2015.
First confirm that you are using PS900 series (902,904,906 or 914) power supply.
1. Measure the DC voltage at the twelve wire hardness and make sure 24VDC is presented at the connector.
2. Make sure polarity of the voltage is correct. Red is positive and black is negative.
3. If external input (INH) is not used (card reader, key switch, etc.) connect the green wire to red wire.
4. If external inhibit is used make sure normally closed access control contact is connected between green and red wires on twelve wire connector.
5. Make sure two wire connector from Chexit key switch is plugged into the Chexit module.
Q: What is the minimum opening that a Chexit 4 device can be cut down?
A: The Von Duprin CX 98/99-4 feet Rim devices on single doors with 5/8" stops and the standard 299 roller strike can be field sized to fit a minimum of 40.2" door opening.
This answer applies to the motor driven Chexit built after August, 2015.
Q: Von Duprin Chexit device keeps going into alarm by itself.
A: Chexit devices shipped with motor after 8-24-2015.
1. When Chexit device is set for more than zero second rearm time (factory setting is 10 second rearm time) and device goes into alarm immediately that is an indication of fire alarm activation. Make sure normally closed fire alarm contact is hooked between yellow and red wires of the twelve wire of the Chexit cable.
2. When Chexit device goes into alarm after the rearm time, that is the indication of open contact from DPS or RX switch. Make sure DPS (door position switch) and RX contacts are closed, not open. DPS switch connects between orange and red wires of the twelve wire of the Chexit cable.
Q: How do I connect the external inhibit option for the Chexit?
A: For Chexit devices shipped after 8-24-2015 with motor driven connect your normally closed contact from access control system between green and red on the twelve field wire connector of the Chexit device.
For Chexit devices shipped prior to 8-24-2015 with solenoid driven connect your normally closed contact from access control system between green and white or green and red on the ten wire connector of the Chexit device.
Q: Is the Von Duprin Chexit part number 050228 a module or a kit?
A: The circuit board is sometimes referred to as a "module" in the field.
Q: Can RX996 be used to inhibit Chexit
A: For Rim / Vertical Devices:
No, RX 996 trim can not be used to inhibit Chexit. The trim lever can not be rotated while the Chexit is armed, and therefore the RX996 switch will not operate as an inhibit.
For Mortise Devices:
Yes, the RX996 operates independently of the mortise device, and therefore the RX996 switch could be used as an inhibit. Q: What are the amperage and power supply requirements for the Von Duprin Chexit (CX) devices?
A: Chexit motor driven devices shipped after 8-24-2015:
You can use 1 Chexit device with PS902, 3 Chexit devices with PS904, and 4 Chexit devices with PS914 or PS906 power supplies with proper gauge wire.
The motor driven Chexit operates with 24VDC and requires a 1.25A inrush and 390mA holding current.
No option cards are required with PS900 series to operate the motor driven Chexit device.
Fire alarm contact ties directly into the motor driven Chexit device. Q: What is the part number for a horn on the Chexit?
A: If the horn fail to operate in the CX device you need to replace the Chexit module.
040086 is the part number for devices shipped after 8-24-2015 with motor driven.
050228 is the part number for devices shipped prior to 8-24-2015 with solenoid driven as seen here:Click Here
Q: Do you have a micro-switch with orange wires?
A: The micro-switch with two orange wires is probably the Chexit switch assembly for devices shipped prior to 8-24-2015 with solenoid driven, part number 13-065-00.
Q: How to test the RX switch in a Chexit device.
A: Chexit devices shipped prior to 8-24-2015 with solenoid driven:
If Chexit device goes into alarm with fast flashing red LED after the rearm time, the RX switch may be out of adjustment or defective. By pass the RX switch by shorting the two orange wires together near the plug connector. If device arms properly contact your sales office to locate an authorized representative to replace or adjust the Chexit RX switch assembly.
