Optional Closed Circuit Television Connections; Figure 5: Optional Cctv Unit - Chamberlain SENTEX Infinity Series Installation Instructions Manual

Refer to Figure 3 & Figure 4 and connect the wires from Infinity-controlled devices as follows:
Relay/door 1 .....TB 9
Relay/door 2 .....TB 10
Relay 3 .............TB 11
Relay 4 .............TB 12
Which terminals are used depends on the type of device being controlled:
♦ Dry Contact Closures (most gate operators): Connect wires to NO and COMMON terminals.
♦ Normally Locked Strikes: Connect one wire from the strike power supply to the NO terminal
and one wire from the door strike to COMMON on the same terminal block. Connect the
remaining wires from each source off the board with a wire nut.
♦ Magnetic Locks and Normally Unlocked Strikes: Connect one wire from the power supply
to the NC terminal and one wire from the door strike to COMMON on the same terminal block.
Connect the remaining wires from each source off the board with a wire nut.
Magnetic locks and DC powered strikes produce potentially damaging voltage spikes. Sentex
strongly recommends installing an IN4001 diode across the magnetic lock coil with the cathode
(the banded end) connected to the positive side of the coil, and the anode connected to the
negative side of the coil.
