The AT-SS231 is a wireless alarm output device based on the LoRaWAN® 1.0.2 / 1.0.3 communication protocol. It is designed to receive alarm commands through a configured LoRaWAN network and activate audible and visual warning locally.
When an associated sensor or system event is triggered, alarm information is transmitted through the LoRaWAN network to the management platform. The platform can then send a downlink command to the AT-SS231 to activate its siren and flashing light.
The product is intended for indoor applications where wireless alarm command transmission and local audible/visual notification are required.
Power adaptor — optional.

Specifications above are taken from the product manual.
The AT-SS231 is an alarm output device and does not detect smoke, heat or fire by itself. It requires an alarm command from the configured LoRaWAN network/server platform.
Wireless communication performance specified in the manual includes:
Actual LoRaWAN communication performance depends on the gateway, installation environment, building structure, radio frequency band and project configuration.
The AT-SS231 operates from a DC 12 V power supply and must be connected with correct polarity.
The manual specifies:
Alarm activation is controlled through LoRaWAN communication rather than a conventional hardwired alarm signal input.
The AT-SS231 is designed primarily for wall-mounted installation.
For installation:
Based on the applications stated in the manual, the AT-SS231 can be used for:
