Step 4 ii)
If you need to interrupt a normally closed circuit
or switch, such as for a low-voltage magnetic
door closure:
• Remove the link that is supplied between pin
2 and pin 3 of the connection block at the
bottom of the Receiver
• Then connect pin 3 and pin 4 in series with
the existing switch or circuit.
Please note: the system has been designed to work
in conjunction with existing systems with a maximum
voltage of 24V and current of 1 Amp.
Step 4 iii)
For any other arrangement, for example to switch
a mains voltage circuit on or off, you can connect
an appropriately rated relay with a 12V coil to pins
5 and 6 of the connection block at the bottom of the
Receiver, leaving the link which supplies 12V from
pin 2 to pin 3 in place.
The system has been designed so that you could
even use a double pole double throw relay to
momentarily disconnect an existing 12V strike
circuit and operate it with power from pin 3.
The diagram below explains the pins on
the connection block at the bottom of the
Locca Receiver.
Maximum voltage 24V.
Under no circumstances should mains voltage
connections be made directly to the terminal block.
