An "active" RS-485 data bus hub designed for jobs where an M1Gold or M1EZ8 Control is retrofitting an older panel that has multiple homerun 4 conductor keypad/data wires. It splits the main 485 data bus into 4 managed 485 branches. Each branch can have 2 parallel home run cables for a total of 8 home runs. The end of each cable is EOL terminated to insure proper operation and supervision.
Includes:
- ELK-M1DBHR Data Bus Hub
- ELK-SWG Circuit Board Mounting Glides

The RM-2 Relay Module is used as an end-of-line (EOL) power supervision module for 4-wire smoke detectors. The RM-2 is used with the Polarity Reversal Module PRM4W and DSC FSA-410 series smoke detectors. When the PRM-4W reverses polarity on the smoke detector loop to activate all smoke detector sounders, the RM-2 Relay will continue to operate normally (regardless of input power polarity). Refer to the PRM-2W/4W Polarity Reversal Module
