Viking CTG-2A networked clock controller telephone accessory

SKU CH-S17J-4DASS

Networked clock controller schedules up to 14 programs with 1,000 events, NTP sync, six minutes of CD-quality WAV storage, 14 tones, four trigger inputs, and a built-in 1-watt amplifier for paging

  • Up to 14 schedules automate daily timing
  • Six minutes of CD-quality WAV recording store custom messages
  • Four programmable trigger inputs activate emergency tones automatically
  • NTP clock synchronisation keeps time accurate across the network
  • Built-in one-watt mono amplifier drives paging directly

Networked clock controller

The Viking CTG-2A is a networked clock controller designed for telephone paging systems in schools, factories or offices. It manages scheduled tones, messages and emergency signals across a facility using a single programmable unit. Administrators configure up to 14 schedules and 1,000 events through included PC software or remotely via TCP/IP. The device suits installations that need centralised time‑based audio control.

Sustained operation behaviour

The controller maintains accurate time using programmable NTP synchronisation, automatic Daylight Savings correction and leap‑year adjustment. A non‑volatile memory provides four days of clock back‑up if network or mains power is lost. Time base selection allows operation from the network, 50/60 Hz mains or an internal oscillator. Trigger inputs and page outputs respond reliably during continuous daily cycling without drift.

Replaces separate timing hardware

This unit replaces standalone master clocks, separate tone generators and manual paging amplifiers by combining scheduling, audio playback and relay control in one enclosure. The jump is worthwhile when a facility needs more than a handful of daily events, requires ANSI S3.41 evacuation signals or must drive remote Viking CL Series clocks over RS485. Buyers who only need a simple bell timer or have no network infrastructure will not use the full feature set.

Questions about this item

How much heat or noise does the Viking CTG-2A generate during continuous 24-hour operation?

The unit uses a built-in 1 watt mono audio amplifier and has no moving parts, so it runs silently with negligible heat output during all-day use.

What existing equipment is required to program and operate the CTG-2A?

You need a PC for the included programming software, a TCP/IP network connection for remote configuration, and a PABX or paging system for the isolated audio output.

Can the CTG-2A synchronise with older Viking CL Series clocks already installed on site?

Yes, it provides RS485 clock SYNC terminals specifically for Master Clock control of Viking CL Series RF synchronized clocks.
