D) Alarm System Connection - Conrad 75 22 27 Bedienungsanleitung

• Connect the open collector output of the code lock transistor to the "Lo-CONTROL" contact.
Put the jumper "Lo" in the position "0" (this means that the external timer of the code lock is
used to activate the door opener for the time set in the timer).
• Connect the door opener to the emergency power supply. Observe the information on "Fail
Safe" or "Fail Secure" door openers below the figure on the previous page.
• The buttons for the door opener (usually "N.O." button, closer) are connected to the code
lock. Several buttons can be switched in parallel. Observe the operating instructions for the
code lock used by you.
• The duration for which the door opener is triggered must be set on the code lock used by you!
The emergency power supply timer is deactivated.
• Connect the 12 V output of the emergency power supply ("+" and "GND") to the code lock's
12 V input.

d) Alarm System Connection

The 12 V output of a connection / switching channel can, of course, also be used for another
device with an operating voltage of 12 V/DC.
This can be an alarm system, as well as an emergency light.
