Viking’s model 

CTG-2A

is a networked clock controlled tone/message

generator designed to provide accurately timed tones and/or messages
over your existing paging system. This provides a cost effective way of
signaling school period changes, factory shifts, breaks, lunch periods,
etc. The 

CTG-2A

has four programmable trigger inputs which are ideal

for triggering emergency alert tones/messages to indicate fire
evacuation, severe weather, lock down, all clear or can be used in store
caster applications for “customer service required” announcements, etc.
The 

CTG-2A

can also be used as a master clock to synchronize Viking

CL Series

wireless clocks (see DOD# 466).

The 

CTG-2A

comes equipped with up to 6 minutes of CD quality WAV

file audio storage for up to 14 different tone/messages. The unit is
factory loaded with common school, business and factory tones but can
be programmed with your custom tones/messages or updated from the
list of WAV files from the Viking web site. 

The 

CTG-2A

can be programmed with up to 14 schedules and up to

1,000 events allowing you to program an entire year or multiple years
of schedules in advance. The 

CTG-2A

’s extremely accurate time base

can be manually synchronized, synchronized with 50 or 60 Hz power
or can be programmed to periodically synchronize to 

network or

internet time.

•  Signal the beginning and end of class periods, breaks and lunch periods for schools

•  Signal the beginning and end of shifts, breaks and lunch periods for factories/businesses

•  Provide trigger controlled emergency alert messages for fire, flood, severe weather, lock

down, etc.

•  Provide messages at specific times for store sales, promotions, closing times, airport

loading zones, etc.

•  Provide Auxiliary contact activation at specific times for specific durations for controlling

lights, cameras, unlocking doors/gates, etc.

•  The 

CTG-2A

can also be used as a Master Clock to synchronize 

Viking CL Series

wireless clocks (

DOD# 466

)

The 

CTG-2A

comes with programming software and a network port to

allow PC programming of timed events, schedules, clock
synchronization, wave file download, message volume, day light
savings time, auxiliary relay control, etc.

Installation requires the assistance of a

Network Administrator / IT Technician.
