Voice Terminal Wiring

CONNECTlNG VOICE TERMINAL WIRING TO THE CONTROL UNIT

You can connect up to 120 station jacks, which support up to 120 voice terminals in the MERLIN II system.

NOTE: The terms “voice terminal” and “station” are synonymous when describing the wiring and labeling of the voice terminal side of the MERLIN II system.

Up to 60 stations can be connected with the Voice Announcement to Busy Voice Terminal or Simultaneous Voice and Data features. Both of these features require the use of two adjacent odd/even jacks on the control unit for each station that is connected with the feature. Because they require two voice-pair wiring, use of either of these features decreases the system’s voice terminal capacity. See “Wiring a Voice Terminal for Two Voice- Pairs” on page 2-27.

NOTE: The default intercom numbers (10 through 69 and 700 through 759) should not be confused with the station jack numbers (01 through 120) that identify the sequential station jack locations on the modules. Intercom 10, for example, is located in the first station jack on the first station module of the control unit, labeled 01. The “odd/even” in this type of wiring refers to jack numbers, not intercom numbers.

You can connect the voice terminal locations either directly, with modular voice terminal cords, or through building wiring to a jack field at the control unit location.

Jack field wiring is the recommended method for installations with more than 30 stations. Direct connection is recommended for installations with fewer than 30 stations. Determine which method to use to connect the voice terminal wiring to the control unit and follow the appropriate instructions below under “Connecting Voice Terminal Wiring Through a Jack Field” or “Connecting Voice Terminal Wiring Directly.”
