The GGT-1F is a DTMF (Dual-Tone Multi-Frequency) decoder field installation kit designed for use with Callbox XT models. This decoder board enables the callbox to receive and respond to DTMF tones sent from compatible two-way radios, enhancing remote access and control capabilities.
Key Features:
- DTMF Signal Decoding – Allows Callbox XT models to receive DTMF tones from radios equipped to send them.
- Relay Board Integration – Includes a decoder board and relay board for seamless operation.
- External Power Requirement – Due to space limitations, this kit cannot be used with D-cell batteries. The 6 D-cell battery holder must be removed, and the unit must be powered by an external 12V power supply (not included).
- Factory-Installed Component – This kit is installed at the factory and must be ordered at the same time as the Callbox XT.
Ordering Information:
The GGT-1F is a factory-installed upgrade and cannot be retrofitted in the field. To ensure proper installation, it must be purchased alongside the Callbox XT unit.
For reliable DTMF-controlled communication and access management, the GGT-1F is an essential addition to your Callbox XT system.
