The NCS-C411 Trunking Delay Module is a “must have” when connecting trunking system radios to the NCS-C250., NCS-C251, NCS-C150 or NCS-C151. When installed between any of the devices and the trunking radio, the NCS-C411 delays the transmitted audio and PTT release while the trunking system acquires a clear channel. This allows the operator to transmit immediately after pressing the PTT without losing syllables or words at the beginning of the transmission. The NCS-C411 is easily installed and requires 12 VDC @ 250mA. The interface cable to the appropriate switcher and power cable are provided. Setup is simple and requires selecting the proper acquisition delay time for your trunking system. The C411 can be provided on a 1U 19″ rack panel. The panel will accommodate up to 3 units.
