The Detex EAX-500 is designed for applications that require an alarmed exit device on secured doors. The alarm, with
approximately 100dB, will sound when someone attempts an unauthorized exit. The EAX-500, with it's smaller size
makes it the choice for quick and easy installations on emergency exit and restricted doors.
OPTIONAL:
Cylinder nut socket

OPERATIONS
SPECIAL NOTES and DEFINITIONS:
1. The door needs to be closed to test the unit.
2. When operating the ON/OFF switch, there is a slight delay.
3. The key is inserted and removed only in the vertical position (home position).
4. Key function: counter clockwise (CCW) = Armed; clockwise (CW) = Disarmed
5. Outside Key Control (OKC)
The bottom left hand switch is only used when the outside key control function is used. This allows
entry from outside. It bypasses the alarm & rearms in 15 seconds after the door closes. The OKC
will not arm or completely disarm the alarm as the inside key does. When in Extended Bypass mode
(Auto Rearm switch OFF) the unit will not rearm until 15 seconds after the door closes. The door can
remain open if desired. When in the Timed Bypass mode (Auto Rearm switch ON) the unit will arm
after 15 seconds & go into alarm if the door remains open.
6. If re-handing is necessary, momentarily short across the Mag Rst (orTest) jumper contacts,
remove battery and follow the handing steps below.
MAGNET HANDING PROCEDURE: Magnet handing is where the device determines if
the left, right or an external reed switch will be used to indicate if the door is opened or closed.
When the battery is initially installed, the device simultaneously flashes the LEDs and chirps the
siren a total of five times.
This indicates that the device is in the magnet handing process:
Step 1: Turn the key CW to the 'OFF' position and connect the battery.
Step 2: With the door open, install the device on the door.
Step 3: Turn the key CCW to the 'ON' position. The red LED blinks twice.
Step 4: Close the door or bring the external magnet into position on the desired side of the device.
The siren chirps and the LED flashes on the selected side of the device (red LED flashes
for the left side or external; green LED flashes for right side).
The device will now operate normally, and the selected reed switch side is stored in memory so
changing the battery does not require re-handing.
RE-HANDING:
If re-handing is necessary, remove the unit
from the door and momentarily short the Mag Rst (orTest)
jumper contacts, remove the battery and repeat the steps above.
OPERATIONS:
To arm the system, close the door and turn the key CCW to the 'ON' position.
The red LED will blink twice followed by the green LED flashing for the remainder of the arming
time (default 15 seconds). After the arming time, the green light will turn off and the siren chirps/
red LED flashes three times. The device is now armed and if the door is opened the alarm will
sound and the red LED turns on.
DISARMING:
To turn off the alarm or disarm the system, turn the key CW to the 2 o'clock position.
AUTO REARM:
With the Auto Rearm switch 'ON', alarm shuts off two minutes after closing the door.
EXTENDED/NON-EXTENDED (TIMED) BYPASS: With the Auto Rearm switch in the 'OFF' position, the unit operates
in the extended bypass mode. This mode prevents the unit from arming while the door is open. Converslely, with the Auto Rearm
switch in the 'ON' position, the unit operates in the non-extended (timed) bypass mode. This mode allows the unit to arm regardless
of the doors position. If the door is not closed at the end of the arming delay, the unit will go into alarm.

(under AUTO
REARM switch)
LOW BATTERY ALERT: Simultaneous siren chirps and red LED flashes occur at 45 second
intervals when the battery reaches approximately 7 volts. The LV Opt jumper must be in place for
this feature (default).
STATUS INDICATOR: With the Status Indicator switch 'ON', red LED flashes every three seconds
when armed; green LED flashes every three seconds when disarmed.
AUTO REARM: With the Auto Rearm switch 'ON', alarm shuts off two minutes after closing the door.
ACTIVATE / DEACTIVATE SILENT ARMING: NOTE: Device must be magnet handed.
1. Turn the key CW to disarm and remove the unit from the door if installed.
2. Remove the battery.
3. Turn the key CCW to the 'ON' position. Hold the OKC switch lever (see Step 3) closed and install
the battery. The unit chirps twice when silent arming is turned 'ON', and chirps once when silent
arming is turned 'OFF'.
4. Release the OKC lever and turn the key CW. Reinstall the unit on the door.
OPERATIONS (con't)
Probable Cause
Problem Action
Device is not powering up 1) Battery not properly installed.
2) Cylinder microswitch lever broken.
3) Cylinder installed incorrectly.
