 Modbus TCP, Modbus RTU protocol
 Photo couple input, Open Collector output
 Wide power supply range
 Wide operating temperature range
 Piezo Transducer Output
 Water clear upper cover with 8 Ultra-Bright RED LED, or -BR version with 8 Blue +
8 Red Ultra-Bright LED.
 4 Selectable Alarm Tone
 NC/NO Input Selectable
1.1.1 Features Description
The ALM-Horn series device accepts any dry contact to trigger DI input, when the
alarm been trigger it output from Piezo Transducer, LED’s & open collector DO.
ALM-Horn series include 4 kinds of alarm tone, the DIP switch’s select which tone
when DI been trigger, DIP switch also select the DI trigger mode NC (Normal Close) or
NO (Normal Open).
For Communication device, ALM-Horn-WF/ALM-Horn-MRTU it also accepts
Modbus protocol to monitor DI status and remote trigger 4 kinds of alarm tone
(independent with DI trigger mode DIP switch select).
It has 2 way to make ALM-Horn use as standard siren just supply power without DI
input, one, just switches DI trigger mode to NC (Normal Close), another is short the wire
of DI input with GND.
