Wiring these telephone entry systems are the same as section 2.3.1 EXCEPT for the expansion board connection. Up to 8
boards can be wired to the circuit board’s Aux Terminal #7 thru #9 instead of a weigand input device. To connect more than 8
expansions boards, see section 2.3.3 on the next page. All expansion boards must have their own power source. See the
Expansion Board Manual 2351-065 for further information BEFORE wiring expansion boards.
The model 2351 Expansion Board allows you to expand the number of remote entry points
that the 1833, 1835, 1837 telephone entry systems can control. One expansion board is
required for EACH remote entry point.
2.3.2 Wiring Up to 8 Expansion Boards - 1833, 1835 and 1837 Systems
