Figure 3.6 Input Supervision.
The AIM-1/2SL reader inputs can be configured for Supervised or
Unsupervised. End of line resistors must be used in the supervised configuration in order for the circuits to
report the correct state.
3.6.2
Door Contact Input (Door Position Switch)
This is a normally closed input and should have a jumper installed if not used!
Terminal connectors: DC, DCR; AUX1, AUX1R (In Unpaired Mode) (See Table 2.1 )
The door contact input is a normally closed input used to monitor the open/closed status of the door. This will
typically be connected to a magnetic sensor in the frame of the door that will provide a short circuit when the
door is closed and an open circuit when the door is opened. If input supervision is enabled (see Part 3.6.1
above), end of line terminating resistors must be installed. The terminating resistors should be installed at
the door contact end (not the reader end) of the cable.
The reader will use this input to detect when the door is opened and when the door is closed. This
information is processed by the reader and used to generate certain alarm messages. If a door is detected to
be opened for no apparent reason (not as a result of a valid card or PIN use or exit button activation), the
reader will generate a “Forced Open” message. If the door is opened as a result of a valid access request or
exit button activation but not allowed to close within the programmed held open time, a “Held Open” alarm
will be generated.
The reader may also be configured from the host software to allow early strike relay shutoff. Normally the
amount of time that the reader will keep the strike relay activated is controlled by the “Strike Time” setting in
the host computer. This is the amount of time a person has to open the door after being granted access.
This time is adjustable from 0 to 255 seconds (0 = ½ second). If the strike time is configured for 10 seconds
(for example) and the person has already opened and closed the door after 5 seconds, the reader may be
configured to terminate the normal 10 second strike time early (thus not allowing the door to be opened
twice). If the reader is configured for this early strike shutoff option, it is important that the door contact input
is working properly. If the input is not connected or is malfunctioning and the reader detects that the door is
always open, erroneous alarms will be generated and the Strike Time will always be very short (the reader
thinks the people are opening the door quickly), resulting in it being impossible to open the door.
