Introduction:

The ALM-Horn series device accepts all kinds of dry contact to trigger DI input, when the alarm is triggered, it can output from Piezo Transducer, DO of LED/open collector.
ALM-Horn series include 4 alarm tones, the user can specify the tone to be triggered by which DI selected via the DIP switch . And the DIP switch can also be used to select the DI trigger mode to be NC (Normal Close) or NO (Normal Open).

ALM-Horn-WF/ALM-Horn-MRTU features communication function and supports Modbus protocol so that the DI status can be monitored and the alarm tones can be triggered remotely (independent with DI trigger mode selected by DIP switch). 
ALM-Horn can be also used as a general  siren by  supplying power only without DI input; there are two ways: can switch the DI trigger mode to be NC (Normal Close), or short the wire of DI input with GND.
