Introducing The TM-250 Automated Trunking Microphone
The TM-250 is Pyramid's latest solution for users who operate SVR Vehicular Repeaters in conjunction with Trunking mobile radios. All of the Pyramid Communications SVR series Vehicular Repeaters have an integrated Smart Trunking™ protocol, which insures that portable radio users receive the trunking tones from the trunked mobile radio system.
The TM-250 utilizes the enhanced Smart Trunking™ protocol to automate the "double PTT" that is required by the portable radio user in order to access the trunking system on a simplex SVR unit. Because the SVR unit is a simplex device, it does require the user to click the PTT once at the beginning of each transmission to establish a handshake on the trunking mobile radio. The TM-250 eliminates user error by automating this process
Based on the OTTO Storm™ Series speaker microphone, the TM-250 provides quality and reliability for the most demanding environments. The TM-250 works with most trunking systems.
