SWITCH 2
INPUT
DESCRIPTION
1 & 2
Switch Input 2. A closure between these terminals will cause relay 2 to activate for the programmed
strike time or dial a preprogrammed phone number (see 3.1.6).
Do not run high voltage (115 V) power lines and communication lines in the same conduit. These
should be in separate conduits at least six (6) inches apart. Be sure that all phone line wiring is
twisted and completely isolated from ground.
Use only the supplied 16.5 VAC (or U.L. listed equivalent) to power the entry system. Do not power
any other devices (electric strikes, magnetic locks, lights, etc.) from this transformer. Do not
run 16 VAC entry system power lines over 200 feet. It is advisable to keep these wires as short as
possible. Use 18 AWG wire for wire runs up to 100 feet, and 16 AWG wire for wire runs up to
200 feet. Install a low voltage surge suppresser (DoorKing p/n 1878-010 or equivalent) to help
protect the entry system from power surges.
