Chexit™Controlled Exit Device

3

Request to Exit Switch is built into the device to detect when someone attempts to exit. Applying less than
15 pounds to 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 desirable to limit false alarms. If the
Nuisance Audible and 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 contacts (rated 1 ampere, 24 VDC) are provided to give external alarm
indication. These contacts close when the device is in an irreversible alarm condition (If Nuisance Audible is
enabled, they will not close until the push pad has been held for more than 2 seconds). These contacts 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. In cases where the key switch is not used for controlling the
device, a blank cylinder can be used.

Indicator Lamp — The status of the Chexit can be determined by the Indicator Lamp. A masked bezel design
provides wide angle viewing in any lighting condition. 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. The user can select whether or not this horn sounds during a
fire alarm condition.

Door Position Input — An external door position switch can be connected to the Chexit. Doing this gives
added security to the opening and is recommended. If a door position switch is used, it will cause the alarm
to sound if the door is not closed when the device is armed; it will sound the alarm if the door is forced open
while the device is armed; it will provide anti-pass-back by cutting short the rearm time.

External Inhibit Input — This optional input is provided to allow remote override of the Chexit in the armed
condition. It also allows remote reset of the Chexit in an alarmed condition. Typical device connections include
card readers, wall-mounted key switches, or a remote security console. This input is controlled with a Normally
closed switch (open = disarmed).

Fire Alarm Input — This input disables the Chexit immediately upon a fire alarm. The building’s fire alarm
system should provide normally closed contacts which open on 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. The mechanism
will also release upon command irregardless of the force applied to the push pad. An override spring prevents
damage to internal components when more than 75 pounds of force are exerted on the push pad.

User Definable Rearm Time —

The Rearm Time is the amount of
time after the device is activated
(via key switch or external inhibit)
before it arms. It is designed to
give someone time to pass
through the door before arming
occurs. 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 Definable 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.

Electric Mortise Lock

The electric mortise lock has all the versatility and advantages of the
standard mortise lock, plus being electrically controllable by a remote
switching device, and access control or automatic fire alarm system.

The E7500 controls the locking of the outside trim. When unlocked,
the door remains latched, preserving the fire rating of the door and
making it particularly useful where codes permit locking, but require
unlocking during a fire emergency.

Standard Features

• Field reversible

• 24 VDC continuous duty solenoid

• Silent operation

• Signalling functions

• Corrosion resistant

• Tamper resistant

• Key mechanically retracts latchbolt

Optional Features

• Fail secure (unlocked when energized, locked when de-energized or
during power failure). Furnished standard.

• Fail safe (unlocked when energized, unlocked when de-energized or
during power failure). Specify with suffix “FS”.

• 24 VAC (by adding SO option)

• 12 VDC or 12 VAC (with SO option)

Note: Some Fire codes will require “Fail Safe” (FS) operation for stair­well doors. Be sure to specify the correct operation for your application.

Electrical Power Transfer

The EPT-10 provides a means to transfer
power from the frame to the door stile in
Chexit applications. It is used in installations
with 4-1/2" x 4-1/2" (114mm x 114mm) butt
hinges or 3/4" (19mm) offset pivots. The
EPT-10 is reversible and allows a full (180°)
door swing. When the door is closed, the unit
is concealed for tamper resistance.

UL approved component for use with listed rim, mortise and vertical
rod fire devices.

Additional Information

Typical Specification

Basic System Design

Each Chexit controlled exit device is an emergency exit system con­sisting of a door or pair of doors equipped with Von Duprin CX99
exit device(s). The system has three modes of operation command:

• Emergency Save Exit Mode

• Secure Mode with Alarm and Conditional Release

• Authorized Exit Mode

Emergency Safe Exit Mode

Whenever the safety detector (smoke, fire, water flow, etc.) signals
that an emergency condition is present to the Chexit, the device will
unlock instantaneously, sound the horn and flash the lamp rapidly.
The door(s) may be opened immediately in the usual manner by
depressing the push pad. After authorized personnel reset the life
safety detector system, the Chexit may be reset by actuation of the
key cylinder located on the device. This will clear the alarm state and
rearm the Chexit.

In the event of a power loss, the electronics become completely
inactive, allowing the Chexit to operate as a normal exit device
providing a means of egress from the building.

How-To-Order Information

1. Product description number.

2. Size 4' (1219mm) — for door sizes 3'4" to 4' (1016mm) to
(1219mm).
Size 3' (914mm) — for door sizes 2'10" to 3' (864mm) to
(914mm) are shipped standard.

3. Door thickness if other than standard 1-3/4" (45mm).

4. Finish, see page 16.

5. Handing, LHR or RHR. Required on “L” and “CD” function, only.
See page 16.

6. “SNB” when using sex bolts.

Secure Mode with Alarm & Conditional Release

The secure mode will operate whenever the doors are latched and
the Chexit is activated to the armed state. This is identifiable by the
slow flashing of the indicator lamp and the device push pad will
appear to be locked. When the exit device on the door(s) is
depressed the horn will sound along with a rapid flashing indicator
lamp at the device. The push pad will remain in a locked state for
the predetermined period of delay of 15 (or 30) seconds. This will
allow time to intercept an unauthorized person who may be trying
to exit. After the delay period, the push pad will retract the latchbolt
permitting egress from the area. The horn sounding and rapid flashing
light will continue until the Chexit is reset by authorized personnel at
the key cylinder on the device.

Authorized Exit Mode

For authorized exit while the Chexit is armed, the door(s) may be
released for a period of time, from 2 to 28 seconds without activating
the alarm by turning key cylinder in counter clockwise or off position
and resetting in clockwise position; system can remain disarmed in
counter clockwise position. This mode is actuated by the key cylinder
or an external access control input which allows the Chexit to operate
as a normal exit device.
