ART.138N AMPLIFIER UNIT FOR THE VX2200 SYSTEM
The Art.138N is a functional digital amplifier unit based on the “2 wire” BUS intercom for the VX2200 system.
Although the Art.138N amplifier unit can be connected up to 24 call buttons the 25H/SP/DDA/2W panel will
already have a US91-15 DDA friendly braille push button pre-wired into the J1 and J2 button harness
(using
the yellow (1) and white (A) wires).
The amplifier can be configured as a MASTER
or a SLAVE panel depending on the number of
Art.138N amplifiers connected on a system, this
can be done by adjusting switch 1 on the 8 way
dip-switch. The default setting is MASTER
(switch
1 in the ON position).
