NANOQUEST USER GUIDE
Issue 02
6-2
If the Auxiliary input (Section 7) is connected to the status output of the intruder alarm system, door
control is disabled while the alarm is armed so that entry cannot be gained even with an authorised
User or Auxiliary card. The alarm must be disarmed first by presenting an Auxiliary card three times in
succession. This feature prevents the risk of an authorised person inadvertently entering the building
and triggering the alarm.
Note:
If the intruder alarm does not provide a status indication to the ‘Auxiliary Input’, there is no
means of confirming its status and therefore the door control can’t be disabled. However, if
the auxiliary output is set to latching mode, it is possible to connect the auxiliary output condi-
tion back into the auxiliary input, thereby disabling the door control when the auxiliary output
is active.
Auxiliary Output Wiring
6.2
The NanoQuest can be used to switch on and off an external device such as an intruder alarm or
lighting. This is an open-collector output that is programmable for latch or pulse operation.

IMPORTANT
To switch mains, inductive loads, or loads drawing more than 500mA, an appropriate
intermediate circuit must be fitted (see example below).
