Tamper
The Tamper input connects to a tamper micro switch assembled within the ACU panel.
The following should be defined:
Single door controller:
Door 1 – IN2
Tamper input is activated when the panel is opened through vandalism. The system has two
additional tamper inputs on the reader terminals.
General
The General input connects to any general-purpose dry contact input.
Single door controller:
Door 1 – IN2A
This function can be used when activating the general-purpose output connections (for
example, alarm sensors, monitoring power supply failure, etc.). The ACU reports activation if
this input changes status.
The system has four output relays. Their contacts are voltage free and rated 5A at 12V AC or
DC. This indicates that output is very versatile and can operate virtually any electrical
equipment including Fail Open and Fail Close locks, electric gates and so on.
Outputs
We recommend using a suppression diode for all outputs.
Door Lock
There are two types of door locking devices:
Fail open (fail secure)
Fail close (fail safe)
The user can select either normally open or normally closed output contacts.
The following should be defined:
Single door controller:
Door 1 – OUT1
Double door controller:
Door 1 – OUT1
Door 2 – OUT2
The output can sink current from any power supply (see page 35). In a time zone door locking
is activated in the following modes:
Grant Access
Automatic Relock
