General Description:

The HM201-R can be installed in a single gang junction box directly behind the monitored unit. It is a addressable output module for installation on the 2-wire communication circuit and its location address is written inside the MCU’s EEPROM by the addressable programmer.

The HM201-R has two output modes can be selected:

1. Relay output mode: It contains a isolated set of form Ccontacts, which operate as a SPST switch. No supervision is provided for the notification appliance circuit.
2. Power output mode:It provides supervised monitoring ofwiring to load devices that require an external power supply to operate, such as horns, strobes, or

Upon command from the control panel, the output module will disconnect the supervision and connect the external power supply across the load device.

The external power supply is always relay isolated from the communication loop, so that a trouble condition on the power supply will never interfere with the rest of the system.

Full analog measurement of the supervised wiring is transmitted back to the panel and can be used to detect impedance changes or other special test functions.
