Interoperability and the Common Alerting Protocol (CAP)

Utilizing the technology of XML, WSI provides the Common Alerting Protocol (CAP) message format to the activation of all types of dissemination systems. These include not just our basic Tone Alert Radios (TARs), which are already geographically aware warning devices, but most all tone encoded RF devices as well. This means that virtually all DTMF, 2-tone or single-tone systems can be activated with a CAP message using the state-of-the-art WSI activation systems. In many cases, this system will provide current technology to activate legacy systems.

Software Tunable Tone Alert Radios
All WSI radios have a software tunable front-end. This allows the operating frequency to be changed within its range without any hardware modifications.

Secure Web-based Activation System
WSI activation systems are web-based with 128 bit encryption and username/password authentication. This allows any networked PC to be utilized securely for activations as well as remote access. If network capabilities are not available, the systems can be accessed directly.

Rapid Response
Send alerts to Tone Alert Radios in as little as 15 seconds by simply using scripted and prerecorded messages.

Selective Activation
Each OnAlert radio has its own unique electronic identification and is individually addressable. You can selectively pinpoint an alert or other message to one or more individual locations or groups. This lets the operator target only the affected parties, avoiding the unnecessary alarming of the broader population. Radios can be grouped by geographic zone or common interest, e.g. all schools or all hospitals.

Multi-Site Activation
WSI offers the ability to trigger Tone Alert Radios, as well as DTMF radios and/or sirens, 2-Tone paging systems and EAS. These activations can be done from a client computer, directly or over a LAN to the OnAlert server that communicates directly to the transmission system or encoder. This allows multiple permitted PC users on a LAN to access the server for activation of any of these alert and notification systems. With this capability, the emergency manager does not have to go from one device to another to activate different systems as activation is centralized in a convenient web browser from a computer on the LAN.

Live and Pre-Recorded Messages for TARs
In addition to pre-recorded messages and synthesized audio, a microphone lets the operations center broadcast a live message to the targeted individuals or groups.

VHF and UHF Operating Frequencies
OnAlert TARs operate on channels in the VHF frequency band from 150 - 170 Mhz and in the UHF band from 850 - 870 Mhz. AdaptAlert TARs operate in the 150-170 Mhz range.

Battery Backup
A warning device is of limited use if the receiver depends on uninterrupted power service for its operation. ONALERT warning receivers use high energy, lead acid batteries which can power the units for more than six hours in standby mode and operate the audible sirens and message functions for more than one and a half hours. The batteries are continually maintained at peak energy levels by special integrated circuits.

Emergency and Weather
The WSI system can transmit both your emergency broadcasts and other programming sources, such as NOAA weather broadcasts. With the push of a button, the customer’s receiver can be used to hear the NOAA simulcast. However, any emergency transmission will override the NOAA broadcast.

Automatic Testing
Automatic testing is integral to the design of the ONALERT system and is conducted in a manner that is not noticeable to the user. Test commands issued from the transmitter continually compare the time stamp on these messages to the microprocessor clock time at the receiver. If there is disparity in the two times or if the receiver has not heard from the transmitter within 24 hours, the receiver will begin to chirp. The user can then contact the system control center to remedy the problem.

Documented Usage
Printed and electronic reports - generated automatically - document the individual operator, activity time, type of message sent, and to whom the message was sent.
