ES-S502 Smoke sensors can detect smoke generated during fires. Smoke sensors use photoelectric smoke sensing devices and excellent production technology. They work stably, have beautiful appearance, are easy to install, and do not require debugging. They can be widely used in shopping malls, hotels, shops, warehouses, computer rooms, residences and other places for fire safety detection. The smoke sensor has a built-in buzzer, which can emit a strong sound after the alarm. The smoke sensor uses standard 485 signal output and ModBus protocol to support secondary development.
