Electrical Options
Alarm Kit – ALK
The ALK battery alarm kit is a simple yet effective way to deter unauthorized use of an opening. While the exit device is still a means of egress, the ALK kit contains an internal horn. When the touch bar is depressed, the horn sounds to provide an audible means of signaling that the opening has been violated. The alarm kit can be armed or disarmed by key. Thus allowing the exit device to be set in an armed or disarmed mode. The horn is rated at 85 decibel.

The key switch uses a standard 1¹|4" (32mm) mortise cylinder with a straight cam (Schlage Cam reference B502-191). The unit operates on one standard 9-volt alkaline battery. When the battery is weak, the horn will emit an intermittent low battery alert signal.

Also can be powered using the PS9 Power Supply. See PS9 for additional information.

Alarm kits are available with a choice of two switch kits, RX or LX. RX monitors the touchpad and is furnished standard. LX optional latch bolt monitoring is recommended for use with surface vertical rod exit devices. Specify ALK-LX.

The ALK is available in two styles, 33A/99ALK, grooved cover and 35A/98ALK, smooth cover.

The ALK includes “EMERGENCY EXIT ONLY. ALARM WILL SOUND” decal for application on door, or the SS push bar trim can be used instead of the door decal,specify SS push bar trim.

The ALK is available with 2 optional circuit boards. External Inhibit (EI) allows for the use of external switch to be used to arm, disarm and reset the alarm. Auto Reset (AR) rearms the alarm after a preset time. AR is available in three factory set times – 1¹|2, 3 or 6 minutes.

Request to Exit — RX
The RX (Request to Exit) feature is used to signal the use of an opening. This device is equipped with one internal SPDT switch which monitors the pushpad.

The device can be connected to a security console, or may be used as a single door alarm when used with a horn and power supply. A continuous current electric transfer must be used for transferring power from the frame to the door.

The RX switch option should not be used to control a load, but as a signalling switch (0.5 amps. resistive maximum).

The RX switch is available in a low current (LC) switch. Most commonly used in computer operated monitoring systems.
 
Latch Bolt Monitoring — LX
The LX feature is used to signal the use of an opening. This device is equipped with one internal SPDT switch which monitors the latch bolt. The device can be connected to a security console, or may be used as a single door alarm when used with a horn and power supply. A continuous current electric transfer must be used for transferring power from the frame to the door.

The LX switch option should not be used to control a load, but as a signalling switch (0.5 amps. resistive maximum).

The LX switch is available in a low current (LC) switch. Most commonly used in computer operated monitoring systems.

Electric Latch Retraction — EL
The EL feature allows for the remote unlatching of exit devices. A control station operator can flip a switch to retract the latch bolt and immediately change an exit door to push-pull operation. A powerful, continuous duty solenoid retracts the latch bolt, either for momentary unlatching, or for extended periods of time. The EL feature is an alternative to manual dogging. If manual hex-key dogging is required, specify HD-EL.

EL devices are also useful with automatic door operators, and may be applied to fire-rated applications when under the control of an automatic fire alarm system.

UL approved for Class II circuit applications.
The EL option does not include the power transfer from door to frame, the power supply, or the control operator. Refer to EPT-2 power transfer and the PS873 power supply.
The PS873 with the 871-2 option card is minimum option card required. Other option cards available for other functions.

Solenoid Specifications:
Continuous Duty –– 24 VDC
Current Inrush –– 16 Amps
Current Holding –– 0.3 Amps

Signal Switch — SS
Monitors pushpad and latch bolt
The SS feature is used to signal the unauthorized use of an opening. This device is equipped with two internal SPDT switches. One switch monitors both the pushpad and the latch bolt assembly, making the latch bolt tamper resistant, for positive security. An additional SPDT switch is connected to the 1 ¹|4" (32mm) mortise with straight cam for alarm “bypass.” (Schlage cam reference B502-191). The device can be connected to a security console, or may be used as a single door alarm when used with a horn and power supply. A continuous current electric transfer must be used for transferring power from the frame to the door.

5 1/2" butt hinges – 130° swing,
6" butt hinges – 110° swing,
3/4" butt offset pivots 180° swing.
Not for use with swing clear hinges or center-hung pivots.
 
Pneumatic Controlled Exit Devices–PN
The PN feature provides remote latch bolt retraction in hazardous areas where electrically operated devices would not be permitted. The pneumatic solenoid will retract the latch bolt for momentary or prolonged periods. PN exit devices are particularly suited for use with automatic door operators. The PN feature is available on both Panic and Fire Exit Hardware devices.

The PN feature includes a special actuating linkage that gives building owners the option of mechanically or pneumatically dogging the exit device. If manual hex-key dogging is required, specify HD-PN (Dogging the device, whether mechanically or pneumatically, makes the device function as a push/pull unit and reduces the wear on its moving parts.)
When activated pneumatically, the latch bolt(s) of the exit device retract in ¹|2 to 1 ¹|2 seconds. This pneumatic operation uses air pressure ranging from 50 to 100 pounds per square inch.

This product will function only when it is part of a pneumatic system (air compressor, air lines, pneumatic system, etc.). Contact LCN for correct control boxes.

Less Dogging – LD
Less Dogging is available in all 33A/35A Panic Exit devices to remove the dogging option.

Cylinder Dogging — CD
Cylinder dogging is available on all 33A/35A Panic Exit devices to replace the standard hex key dogging. Unit requires a standard 1¹|4" (32mm) mortise cylinder with a straight cam (Schlage Cam B502-191 reference).

Cylinder Dogging Kit — CDK
For field conversion, a cylinder dogging conversion kit is available. Cannot be added to fire exit hardware.

Hex Key Dogging Kit — HDK
For field conversion, a hex key dogging conversion kit is available. Cannot be added to fire exit hardware.

Dummy Pushpad
The 330 dummy pushpad is designed as a companion unit for all 33A devices. The 350 dummy pushpad is a companion unit for all 35A devices. The pushpad is rigid or nonfunctioning. A push/pull operation can be accomplished by using 386DT, 360L-DT, 550DT, 392-6 trim or any Ives Pull.

The 330/350 can be equipped with a functional pushpad and will accommodate an RX switch. Specify RX-330. May also be equipped with the RX2, double RX switch. Specify RX2-330.
 
Vertical Rod and Latch Guard — RG-27
Series RG-27 Vertical Rod and Latch Guards protect the bottom rods of exit devices from the damaging impacts of carts or gurneys passing through doors. (If bottom rods become damaged, the exit device will not function as intended and can jeopardize the ability to exit safely during an emergency.)

In addition to protecting the vertical rod, the guard provides a smooth, unobstructed surface so the door can be pushed open easily with the bumpers of a wheelchair. The latch guard portion is 10" high. The standard latch guard features a 45° ramp. The extended latch guard offers a continuous ramp in 3' or 4' widths.

All stainless steel construction in US32D finish. Latch guards can cover latches as large as 1¹|4"W x 10"H x 17|8" projection.

Less Bottom Rod – LBR
LBR option is available, using a spring loaded auxiliary latch bolt installed in the lower door edge. When exposed to heat the auxiliary latch bolt releases, keeping the doors in alignment and closed during a fire. UL listed 3 hours on hollow metal doors double egress, 90 minute swinging same direction, and 20 minutes wood doors (consult wood door manufacturer). Fits door stiles as narrow as 35|8".

LBR devices must be ordered in pairs or must be used in conjunction with an approved automatic or constant latching flush bolt.

LBR used on non-fire rated devices, the spring loaded auxiliary latch bolt is not required. Device is supplied less bottom rod, latch and strike.

Pullman Latch – PL
When PL is specified the standard latches are replaced with pullman style latches. Pullman latches are always extended and are most commonly used in conjunction with electric strikes and LBR-less bottom rod application. Not available with Fire rated devices. Not recommended where security is of the utmost since latches do not deadlock.

Glass Bead Kit – GBK
Glass bead conversion kits are available for all 33A/35A Series devices for use on doors with raised glass beads. Each kit consists of 1/4" (6mm) shim sets. GBK for Surface Vertical Rod ships with 1/8" shims for rod guides.
 

Antimicrobial Coatings for Exit Hardware
Hospitals, schools and food service facilities experience high traffic every day, even in areas that aren’t open to the public. Von Duprin can help you combat bacteria on panic and exit hardware with an antimicrobial coating that provides lasting protection.

The vast majority of bacteria are rendered harmless by the human immune system, but a few are responsible for infectious disease. The antimicrobial coating on Von Duprin exit devices works to protect the hardware’s surface by inhibiting the growth of bacteria, mold and mildew.

The coating is made using ionic silver (AG+), a single atom that is missing one orbital electron that interacts with the bonding sites on the microbe surface. The result is that silver ions surround bacterial cells – blockading food and respiration supplies, hindering the bacteria from reproducing.

Chexit® Delayed Egress
Chexit controlled exit device is for use on panic or fire exit hardware applications. Designed for use on delayed exit applications, the Chexit system is ideal for highly controlled areas such as computer rooms, research and development labs, etc.
 
All controls, auxiliary locking, local alarm and remote signaling are self-contained in the Chexit, providing safe, secure, easy-to-install and simple-to-operate door control exit hardware.
 
This style of delayed exit systems combines life safety with the needs of security. Meets all requirements of NFPA 101 for "Special Locking Arrangement and UBC Special Egress - Control Devices."
 
Devices are UL/cUL Listed "Controlled Exit Panic Device" SA8972, "Special Locking Arrangements" (FWAX) SA8170 and as fire exit hardware (GXHX) R4504 A Label.
 
Solenoid Specifications
  • Continuous Duty – 24VDC
  • Current Inrush – 16 amperes
  • Current Holding – .3 amperes
Requires PS873 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 2 seconds 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 2 seconds or more.
 
Remote Alarm
A set of relay contact are provided to give external alarm indication. These contact close when the device is in an irreversible alarm condition. These 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.
 
Door Position Input
An external door position switch can be connected to the Chexit.
 
External Inhibit Input
This optional input is provided to allow remote override of the Chexit in the armed condition. It also allows remoe 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 after 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.
 
Quiet Electrified Latch (QEL) Exit Device
The QEL option provides electronic control of an exit device and is ideally suited for environments where limited operational noise is desired. The QEL option allows for the electronic unlatching of exit devices for continuous push-pull operation and/or access control and can be activated through a building automation system, access control system or by a control system operator. The device always provides mechanical egress but can also be tied to an access system to unlatch when a credential is presented or may be held unlatched (dogged) for extended periods to provide free entry.
 
If manual dogging is also required, special center case dogging is available for 98/99 rim and vertical systems, specify SD-QEL.
 
QEL devices are also useful with automatic door operators, and may be applied to fire-rated applications when under the control of an automatic fire alarm system.
