3) BASIC WIRINGS OF AN INTER-LOCK SYSTEM USING TWO KEYPADS
An inter-lock system needs two door controllers. This application example uses two keypads with
simple cross wire connection on their
"Output 1 INHIBIT"
and
"Inter-lock Control Output"
terminals. It is necessary to link up the
"(–) GND"
terminals of the two keypads as common ground
to achieve the inter-lock logical functions.
●
Use keypad to open the door from outside.
●
Press egress button to open the door from inside.
●
Connect the door magnetic sensors on the door 1 and door 2 to monitor their positions.
●
During the time that door 1 is open, then, door 2 is forced to keep closed, or vice versa.
●
Relay output 2 is independent and has nothing concern with the inter-lock system. It may be used
for other applications, such as controlling security systems, automatic operators etc.
