Figure 4-12: Connections for Internal Relay Operation

The power supply for the external relay must be chosen to match the operating voltage and cur-

rent of the external relay coil, but its voltage must not exceed the V-Station 4G or V-Flex 4G de-

vice's internal relay maximum voltage rating of 250 volts.

The external relay should be connected in accordance with Figure 4-13 below. Note that snub-

ber diodes (1N2007 or equivalent) should be connected across the external relay coil and the

deadbolt/door strike.
