Audible and visual alarm module
Ever questioned yourself if that roof fan is still working properly? ALR-M1 was designed to generate alarms and indicate failures or alerts of installations in less accessible places.
Audible and visual signals | Three LEDs and a buzzer can be activated via Modbus RTU to indicate normal operation, alert or alarm.
Modbus RTU | ALR-M1 needs a Modbus master unit that is able to write a value in the correct Modbus holding register.
Predefined or custom functionality | Next to the predefined alert and alarm programs, there is also the possibility to customize the functionality.
External devices | Up to three external devices, such as an alarm bell, warning light or similar can be controlled via the open collector outputs.
