The SIGA-TCDR EDWARDS Temporal Coder is specifically designed for use with SIGA-AB4GT Sounder Bases, providing precise and effective temporal coding capabilities. With this device, you can ensure reliable and accurate notification in case of emergencies, making it an essential tool for any industry.

The SIGA-TCDR Temporal Pattern Generator is an addressable device that generates CO and fire signal sound patterns for AB4GT and AB4G-LF sounder bases. The control panel sends synchronization and channel commands to the SIGA-TCDR; the channel selection determines the pattern. In the U.S. Channel 1 is TC3 and Channel 2 is TC4. In Europe, Channel 1 is TC4 and Channel 2 is TC3 (in case both channels are activated Channel 1 has priority). Other markets depend on local requirements. The SIGA-TCDR module uses two addresses on the signaling line circuit (SLC). Address 1 is tied to Channel 1; Address 2 is tied to Channel 2. Depending on the type of alarm, the panel can select the corresponding pattern and send the activation command to the SIGA-TCDR. To control all sounder bases in the loop, use a SIGA-CRR module. The panel sends a signal to the SIGA-CRR causing it to reverse polarity. With the polarity on the riser reversed, all the sounder bases on this loop activate. The SIGA-TCDR maintains synchronization by processing the SYNC commands from the loop controller. By integrating the SIGA-TCDR and SIGA-CRR modules, you can create a comprehensive fire alarm system that meets local regulations and ensures timely alerts in emergency situations.
