The Model 2TR9B Tone Alert Receiver uses 2-Tone signaling as its primary decoding method, but has optional features for CTCSS and DTMF signaling. The receiver is available in Lowband (29 - 54 MHz), VHF (136 – 174 MHz), or UHF (406 - 512) frequency bands. It has a single synthesized channel that can be programmed for the desired system frequency and tones. The front panel consists of an On/Off/Volume control, a Squelch control, the Tone/Monitor switch, a message Reset switch, and a Power/Alert LED. The back panel has connections for optional RSO (Remote Switching Output) Relay contacts, a BNC antenna jack, an external speaker jack, and the power jack. The physical dimensions of the unit are 5.5 x 6.9 x 2.2 inches and it weighs about 1 lb. The Veetronix comes with a 1 year warranty.
Another optional feature of the Tone Alert Receiver is an inline battery pack that provides power fail protection. The battery pack uses 8 standard “AA” sized alkaline batteries for operation. The optional programming kit consists of a keypad, cable, and software while allowing the user to set the channel frequency, tones, tone timing, RSO Relay time and more. The RSO option has two relay outputs that are rated 5A @120VAC and can be programmed to activate on separate tones or together on the same tone. The relay outputs can also be programmed for a momentary output or an output up to 20 minutes in 5 second intervals.
