Attendant Intercom Selector
The Attendant Intercom Selector can be attached to a 34-button deluxe voice terminal. The
selector's 30 buttons can be used to access up to 70 Intercom Auto Dial numbers. The light
beside each button indicates whether a voice terminal or basic telephone is busy and whether
its message light is on (voice terminals only).

Optional Control Unit Accessories
Some optional accessories connect directly to the control unit to give the MERLIN system
additional capabilities.
Ring Generator Unit
The Ring Generator Unit must be connected to the Power Module on the control unit to
provide ringing current when basic Touch-Tone or rotary telephones are connected to a Basic
Telephone Module. The Ring Generator Unit looks similar to the Auxiliary Power Unit
illustrated on page 19. However, the Ring Generator Unit has, in place of the Aux Power jack,
a permanent cord with a plug that connects to the Ring Gen. jack on the Power Module.
