About the 4090-5205
Addressable MX Technology module that connects conventional low-voltage detectors and callpoints to the MX Loop. It provides monitoring and zone power for two Class B circuits or one Class A circuit. Zone power comes from a 4100-5130 Voltage Regulator Module in the host panel, and power reset is controlled from the MX Loop module.
Needs regulated 24 VDC from a 4100-5130 Voltage Regulator Module; check two-wire detector compatibility in the installation instructions.
