1. Introduction
The ALM-Horn Series include 3 model, -BR with water clean upper cover, ALM-
Horn as standard siren, Blue + Red LED, ALM-Horn-WF have WLAN connection
complies with the IEEE802.11b/g/n standards, support Modbus TCP protocol & HTML,
ALM-Horn-MRTU have RS-485 interface support Modbus RTU protocol.
ALM-Horn series device includes 1-channel digital input for any dry contact output
such as SA, BA, FA ..etc, and 1-channel digital output. Each device has 4 kinds of alarm
tone, NC/NO input mode select by swatches. The ALM-Horn-WF & -MRTU support
Modbus protocol, Which makes perfect integration for monitoring or control in SCADA
software, HMI Modbus & Utility. ALM-Horn series have High Sound Pressure output,
wide input power range & IP43 waterproof

1.1 Features
 Standard Alarm Siren or with Wi-Fi, RS-485 interface
 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.

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
