4.2.11 Primary/Auxiliary Request to Exit
The Request to Exit (RTE) input accepts a signal from a normally open input device such as a push
button. A signal from this device indicates a request has been made for someone to exit through a
secured door. Push buttons, motion detectors, floor mats, or similar devices can provide the RTE signal.
When the controller receives an RTE signal, it operates the door based on the controller’s RTE
configuration.
A request to exit can be made in two ways: through the primary RTE input and through the auxiliary
RTE input. On a PXL controller, primary RTE is requested through the controller’s RTE input (the
standard implementation) and auxiliary RTE is requested through the controller’s general purpose
input.
On a controller with a Satellite Board configured for 2-door control, the RTE options for the A-door
(attached to the controller) apply as described above. Primary RTE for the B-door is requested through
the satellite board’s RTE input (the standard implementation) and auxiliary RTE for the B-door is
requested through general purpose input 3 on the satellite board.
NOTE: If the auxiliary RTE feature is enabled on the master controller (including an EntraGuard
controller), the Global Unlock feature (see “Set Network Master Parameters” on page 10 in section 2)
is automatically disabled. Both features use the same input so only one of these two features can be used
on the master controller.
There are three door configuration options for primary RTE.
• Disabled – There is no request to exit function at all. Exit is not allowed through that door via RTE.
• Do Not Unlock – The request to exit is recorded and the door held open timer starts, but the door
must manually be opened for exit (typically the door has a manual door strike, crash bar or similar
device).
• Unlock – The request to exit is recorded, the door held open timer starts, and the door unlock relay
unlocks the door to allow exit.
There are three door configuration options for auxiliary RTE: Disabled, Momentary Unlock, and
Continuous Unlock.
• Disabled – There is no request to exit function at all. Exit is not allowed through that door via RTE.
• Momentary Unlock – The request to exit is recorded, the door held open timer starts, and the door
unlock relay unlocks the door to allow exit.
• Continuous Unlock (CRTE) – The request to exit is recorded and any assigned Auto Unlock/Lock
(AUL) time zone is Suspended for a given door. Then, while the CRTE input is active, the door is
unlocked. When CRTE becomes inactive, the door will assume its AUL time zone configuration
state.
The default value for primary RTE is Unlock; the default for auxiliary RTE is Disabled. For example:
• The Emergency Exit does not use the RTE feature. Both primary and auxiliary RTE should be set to
Disabled.
• The Manufacturing Door uses the primary RTE input. Primary RTE should be set to Unlock and
auxiliary RTE should be set to Disabled.
• The Stockroom Door uses both the primary and auxiliary RTE input. Primary RTE should be set to
Unlock and auxiliary RTE should be set to Momentary Unlock.
• The Back Door uses the primary RTE input, but should not automatically unlock the back door.
Primary RTE should be set to Do Not Unlock. Auxiliary RTE should be set to Disabled.
