Unsupervised Request to Enter (RTE) and Request to Exit (REX) inputs. The
RTE input and REX input are normally open inputs sharing the same common
terminal. When momentarily shorted (500 ms) by a dry contact input will initiate
the door sequence. Typical applications include a N/O momentary push button
or a N/O momentary relay activation from a Door motion detector device.
The REX input generates the Door Request to Exit and is used to exit the area
assigned to the D9210B without having to use an ID. The RTE generates the
Door Request to Enter and is used to enter the area assigned to the D9210B.
Programming REX Shunt Only and RTE Shunt Only allows you to initiate only
the shunt and buzz when the RTE or REX inputs are shorted. This eliminates the
need for a strike and would be used in applications where a push bar is used to
open the door.
It is advisable to assign a point number to the device used to activate the RTE
and REX inputs (such as an infrared with addressable ZONEX). This ensures
that the device is supervised.
Unsupervised reader. The Weigand Reader input is a five wire input that
su5 VDC (use the +12 VDC terminal for 12volt readers), negative,
ground activation for the reader LED, (D1) and (D0) inputs for the card data.
Two LEDs are provided to indicate that data is reaching the inputs from the
reader when an ID is read. The IDs do not have to be valid to illuminate these
LEDs, but the IDs do need to have a format that the reader can decipher.
Normal Door Sequence. The Normal Door Sequence of the D9210B is initiated
by a valid access granted (User ID) or door request (RTE/REX). This initiates the
strike, shunt and buzz time to activate the strike, shunt the point and create an
event reporting the door sequence has begun.
When the door is held open past the normal door sequence time, an extended
door sequence time is initiated. This extended time extends the shunt and re-
activates the buzzer. If programmed, [ CLOSE DOOR # ] will display at the
control center assigned to the door.
The normal door sequence will not activate if the interlock point is in an off
normal (open or short) condition.
The INTERLOCK POINT can be assigned to multiple door controllers. This is
useful for applications that require doors to not activate when a point is faulted
until the interlock point is normal.
Door States. There are four door states for the D9210B. These door states can
be controlled through the control center, the Remote Account Manager (R.A.M.),
scheduled events (Skeds) and automatic programmable functions in the D9210B
parameters.
Locked Door. This state is considered a normal door state in that the strike is
holding the door closed.
Unlock Door. This state allows the door to be opened for free access.
Secure Door. This state will not allow access unless a Fire Unlock occurs.
