AN913 Direct Access/Direct Dial Option Board

The AN913 is compatible with SS900A, SS900BSS910, SS911, SS912 and SS913 Sub Stations and is mounted on the back of the substation with 4 mounting screws.

The AN913 is designed to work with the RM5000EX and/or CB901EX microprocessor intercom systems.

  • Easy installation
  • Simple wiring
  • Used with a variety of systems and remote stations
  • Works with RM5000EX and/or CB901EX series systems

Input 1: Direct Dial DTMF #3 or Direct Access (depending on SW1-1)

Input 2: Direct Dial DTMF #6

Input 2: Direct Dial DTMF #9

Input 2: Direct Dial DTMF X

SW1-1: OFF = Direct Dial (for Input 1). ON = Direct Access (for Input 1).

SW1-2: OFF = Direct Access call can be canceled from Input 3 or from connected Intercom. ON = Direct Access call can only be canceled from Input 3.

SW2-1: OFF = Normal ADA Operation on Output 1. ON = Reverse ADA Operation on Output 1.


Four (4) transistor outputs are provided for driving external loads. External loads can be relays, lamps, LEDs, small buzzers or auxiliary equipment. The outputs are open collector type dricing to Ground reference. One side of the load should be connected to +24 VDC and the other connected to the output. Each output can drive up to 100mA.

Output 1: ADA

Output 2: Camera

Output 3: Strobe

Output 4: Horn
