4501 OBDE – Operational Description
The door is normally closed and secured by the 4501 On-Board Delayed Egress Exit Device. The on-board status LED
illuminates Green indicating that the unit is secured. The integral Reset/Bypass key switch is in the center position.
Activation/Alarmed Release: Pressing the push pad of the 4501 OBDE device initiates the irreversible 15 second
unlock delay cycle. To prevent false alarms, a pre-alarm audible warning tone is activated during the short nuisance
delay period. Releasing the push pad during the nuisance delay period will silence the pre-activation warning tone,
reset the unlock delay cycle, and keep the door locked.
Once the nuisance delay period has been exceeded, the 4501 OBDE continues its irreversible door release cycle. An
audible tone and Yellow status LED inform the person intending to exit of the door release cycle activation. An alarm
output is activated to alert personnel of an unauthorized exit. After the delay cycle has expired, the status LED
illuminates Red, and power is removed from the locking device, allowing free egress by pressing the push pad. A second
output is activated indicating that the door is unsecure.
Reset/Relock (from an Alarm, REX, or Bypass state): The 4501 OBDE can be manually reset by authorized
personnel by closing the door and turning the integral key switch to the reset position, or by momentarily activating a N/O
switch connected to the remote Reset/REX control input.
Request-to-Exit (from a Secure state): A timed Request-to-Exit (REX) cycle is initiated by authorized personnel by
momentarily turning the integral key switch to the reset position, or by momentarily activating a N/O switch connected to
the remote Reset/REX control input. The power will be removed from the locking device allowing free egress by pressing
the push pad. The on-board status LED will rapidly flash Green (2x / sec) during the REX cycle. After the REX cycle has
expired, the 4501 OBDE will automatically re-apply power to the locking device to re-secure the door. If an external door
position switch is connected to the DPS input, the door will automatically relock on door closure.
Authorized Maintained Bypass (from a Secure state): Unlocking the door for an extended period of time is
accomplished by momentarily turning the integral key switch to the Bypass position, or by momentarily activating a N/O
switch connected to the remote Bypass control input. The power will be removed from the locking device allowing free
egress by pressing the push pad. The on-board status LED will slowly flash Green (1x / sec) during Bypass mode. The
4501 OBDE may be re-secured using the Reset procedure described above.
