P25 Siren Controller

MPSC-1 P25 Siren Controller

Prism-IPX Systems and TPL Systems have Partnered to Develop the Industry’s First, Fully Integrated, P25 Activated Siren Controller, the MPSC-1™

Why P25?

Systems are built with a high degree of redundancy, ensuring message reliability.

Professionally Monitored and Maintained
Given the critical nature of Public Safety communications, any system anomaly has to be addressed quickly to ensure minimum service interruption.

Secure Communications
Provides secure communications to protect against malicious intervention.

Superior RF Coverage
Administrators are continuously investing in improved RF coverage and services

Why Consider the MPSC-1 Controller?

Supports Multiple Systems
In addition to P25, the MPSC-1TM supports legacy analog environments thereby allowing operation on a legacy system with a seamless transition to P25.

Fully Integrated for High Reliability
One PCB supports multiple systems.

Ease of P25 Integration
Due to the MPSC-1TM software design, it will have no impact on P25 System resources.

Status Reporting
The MPSC-1TM supports Internet and 3/4G LTE interfaces, which can be used for alternative activation control and /or operational status reporting.

Its hardware modularity and Software Designed Radio architecture allow for ease of upgrade or redeployment.
