OPTIONAL VISUAL/AUDIO ALERT FEATURE
A 5V ringer (examples: Mallory SC307N and SNP2) or a 5V LED can be connected to the ACH1000 DB9
connector (between pins 3 and 7) in order to signal incoming calls or messages
(see next page’s
Wiring
Diagram
). The alert signal is grounded, lit (on pin 3) when there is an incoming message to be read or
pulses if it is an incoming call. MAX +18V
ADD THESE LATER:
Max switched voltage is +18V.
Pin 3 is grounded only when the ringer is activated.
