The MRI-4042 Analog interface module is designed to be used with a compatible fire alarm control unit, providing high rates of information exchange and fast and secure responses. The MRI-4042 Conventional Zone Module allows a zone of conventional 2-wire detectors to be interfaced to an intelligent loop. It can also be configured to work with 4-20mA devices. An external listed power supply can be connected to several MIX- 4042 modules to provide power to the devices while remaining electrically isolated from the FACP. Each MRI-4042 monitors the current used by the devices and reports alarms and troubles accordingly. When configured for conventional devices, the module will automatically handle Class A or Class B lines. The MRI-4042 has an internal EOL resistor for Class A lines. An MP-300 end-of-line resistor must be used for Class B wiring. The module has a panel-controlled LED indicator. The LED flashes during normal operation and stays ON steadily when the device is in alarm condition.
