Alarm Autodialing
The system is designed to continuously monitor preset alarm points. If an alarm condition is sensed at a monitored point, the Verbatim System will automatically dial a list of 16 pre-programmed emergency telephone numbers, calling until it gets an answer. When the call is answered and acknowledged, the system reports the alarm location and status via pre-recorded voice messages.

Communicating over standard land- line or wireless telephone networks, the Verbatim® delivers alarm messages to standard phones, cell phones, numeric or voice pagers, and voice mail systems, and talks just as easily with computers.

User-Recorded Messages
The voice messages are digitally pre-recorded by the user. Anything that can be spoken is accurately stored in memory from names and numbers to technical terms and detailed instructions. Messages are delivered with maximum clarity, lessening the chance for misunderstanding or error. And, you can easily enter or change your messages over the phone or at the front panel.

A Fully Interactive System
With Verbatim®, you’re never out of touch with your monitoring system. With any standard touch-tone phone, you can call in for a status report, review and change programming, or control a remote device. With the touch of a key, you can listen to local sounds or talk to personnel using the unit’s built- in speaker phone.

When calling for status report you hear a comprehensive summary of all conditions monitored by the system, including internal power. Hard copies of event data alarms, acknowledgements, inquiries, and programming changes can be printed out at any time using the system’s data logging capabilities.

Controls and indicators are provided on the Verbatim® front panels for on-site programming and review of system operation, alarm status, and battery condition.

Supervisory Control System
A Verbatim® System can be equipped with up to 8 digital control outputs to remotely actuate HVAC systems, pumps, compressors, and other electrical devices from a standard phone, the Verbatim® front panel, or a PC.

SCADA System
RACO MMI/SCADA Systems provide monitoring and control of up to 200 RACO Verbatim® Remote Terminal Units (RTUs) over the standard dial-up telephone network. Each RTU has full alarm monitoring, reporting, and autodialing capabilities, and because Verbatim® systems report by exception, they do not need to be polled. When an alarm is sensed, the RTU reports to the central computer. If the computer operator does not acknowledge the alarm, the RTU will commence autodialing.

PLC Network Interface
Offering alarm and monitoring for as many as 96 remote channels, the Verbatim® can use RS232 communications to work with any PLC or other device using Modicon's Modbus protocol.

Take Control of Remote Equipment
A Verbatim® System can be used with a RACO Responder or another Verbatim® to actuate pumps, compressors, gates, or other electrically operated equipment over the dial-up telephone network. Upon receipt of an alarm signal low water level, for example the Verbatim® issues a command to activate an output relay in the Responder or other Verbatim® unit, which initiates an action such as turning on a pump motor.

Memory Retained During Power Failure
Verbatim® systems incorporate a non-volatile memory. Recorded alarm messages and user-entered programming is retained indefinitely in the event of a power loss.

Battery Backup for Safety
A rechargeable gel cell battery provides up to 20 hours of continuous operation in the event of power loss. And because the system uses a precision regulated charger instead of the traditional “trickle” charger, the time required for charging is minimized and battery life is significantly extended.

Built for Long Term Survival in The Toughest Environments
Verbatim® is designed and built for superior performance year after year. The system's rugged durability is evident in its heavy-duty metal enclosure, carefully selected and proven solid state components, and sealed membrane keyboard. Heavy-duty solid-state and gas tube surge protection is provided on all power, phone, and signal lines.
