Viking CTG-1A Clock Controlled Tone Generator, Time Relay Mode, Switchable 50/60Hz

Ensure precise, automated audible signaling across your facility with the Viking Electronics CTG-1A clock controlled tone generator. Designed for schools, factories, healthcare and security operations, this audio communication device produces scheduled bong or buzzer tones and safety signals to mark shifts, breaks, evacuations and emergency events—removing the need for manual paging and reducing human error. The CTG-1A supports a user-programmable 24-hour timer with up to 128 events and two separate schedules, and provides a 600 Ohm line-level audio output with volume control for easy integration into existing paging and surveillance systems. Two DPDT relay contacts allow muting of background audio or activation of external equipment, while three contact-closure inputs enable instant activation of siren, evacuation or chime alerts for monitoring and security response. Built-in non-volatile memory, four-day clock backup and switchable 50/60Hz operation ensure dependable timing and continuity. TAA/NDAA-compliant and manufactured in the US, the CTG-1A delivers reliable, standards-based performance for any facility requiring precise, repeatable audio alerts.
