Th SM336SA can store 2 user profiles and
4 phone numbers. The numbers can have
up to 32 digits.
INSTALLATION
The SM336SA comes from the factory set
up for 90 to 130 VAC. If 180 to 260 VAC
operation is required, the Zero Ohm
jumpers labeled “110VAC” (R8 and R9)
should be removed and the Zero Ohm
Jumper labeled “220VAC” (R10) installed.
These jumpers are located between the
transformer and the fuse on the PC Board.
The SM336SA-12 connects to a 12 Volt
DC supply rated at least to 0.5A. The
Black wire connects to +12V and the white
wire connects to Ground. The green wire is
Chassis Gnd.
The Phone line is connected to the RJ11
connector on the back panel labeled
“LINE”. An exterior phone can be
