Dispatchers, drivers, and security personnel can communicate effortlessly, resulting in smoother logistics, improved incident management, and enhanced passenger safety.

SiRcom HPS TETRA:

The HPS siren remote control units developed by SiRcom GmbH leverage the company’s extensive experience in the field of radio communication, sirens, siren control centers, and accessories. These remote control units serve as tele-control receivers for BOS (Public Safety Digital Radio Network) radio networks and are specifically designed for siren control.

The primary function of these units is to enable secure and straightforward activation of sirens through higher-level control centers. The communication between the remote control units and the control centers can be either unidirectional or bidirectional, depending on the design and protocol used. In the case of bidirectional communication, such as with BDBOS (TETRA) digital radio networks, the units can not only trigger the sirens but also provide monitoring capabilities and send feedback to the responsible authorities.

Ensuring secure operation, protection against sabotage, and ease of use are inherent requirements in the design of these devices. Additionally, they are built to withstand the effects of high-frequency or magnetic field radiation, as well as operate within a wide temperature range. Depending on the specific model, the units can operate independently of the main power supply through a rechargeable battery.

The BDBOS (Federal Agency for Public Safety Digital Radio) network, in conjunction with TETRA digital radio technology, offers advanced capabilities for alerting and feedback in emergency situations. SiRcom, a specialized company in siren control systems, has developed the HPS siren control receiver specifically for integration with the TETRA network of the BDBOS.

Compared to traditional analog radio or POCSAG (Post Office Code Standardization Advisory Group) digital radio systems, TETRA radio networks provide the advantage of two-way communication between the alarm trigger and the sirens. This means that sirens can not only be easily activated but also provide feedback to the responsible authorities regarding the activation status or availability of the siren.

The HPS siren control receiver, designed by SiRcom, offers seamless functionality and interoperability within the TETRA network. SiRcom’s extensive experience in the field and its involvement in the standardization committees for siren control in Germany contribute to the reliable and effective performance of the HPS.
