Construction

The OMA-GUARDIT automatic alarm dialer monitors 4 input channels. Each channel can be configured for an analog or digital signal input. The system utilizes the public telephone network as a basic medium for transmission of alarm messages and status calls. It is field programmable by the user at the system's control panel via a standard touch tone phone handset.

Automatic Alarm Reporting

Upon detection of an alarm condition, OMA-GUARDIT automatically calls a list of up to 8 pre-programmed phone numbers over the standard dial-up telephone network, calling until it gets an acknowledgement. When a connection is made, the system reports the station identity and the specific alarm condition in the form of a digitally pre-recorded voice message. In addition to standard phones in office, plant, or home, the alarm calling sequence can also include calls to pagers, cellular phones, and voice mail.

Local Alarm Relay Output

The OMA-GUARDIT provides a transistor output for TTL or relay drive (500 mA 24 VDC max) activated during unacknowledged

OMA-GUARD IT Alarm Dialer

alarm. This output can be used to activate a local alarm buzzer or light, can be used to remove power to machinery when used with a normally closed relay or activate/ de-activate any device locally when an alarm condition occurs.

Alarm Acknowledgment

An alarm is acknowledged simply by pressing a button on the called phone. When acknowledging an alarm, a built-in microphone permits the caller to listen for background sounds at the site. The user can also call the system from any remote phone for a status report of all points being monitored.

Voice Messaging

The voice transmission consists of a station identification together with an alarm message giving details on the fault. The station identification and alarm messages are digitally recorded by the user. By using electronic voice reporting technology, OMA-GUARDIT eliminates the need for often unreliable audio tape autodialers.

Set-up and Programming

System set-up, voice recording, and programming is accomplished via an external touch-tone phone which plugs into a standard phone jack on the system’s front panel. The user simply follows voice instructions given over the phone.

System Controls

System operating status is provided by front panel LED indicators. System off/disarm/ready controls are provided on front panel. Surge protection and noise suppression are standard.

A Truly Modern Autodialer

OMA-GUARDIT fills the requirement of a modern autodialer–it should be extremely reliable and be able to tell the called party as much information about the nature of an alarm as possible so that the right personnel can respond quickly and appropriately. Many other autodialers don’t meet these requirements.
