This alarm module is to be installed in the hatchery, close to hatchery office usually, which can give sound alarms to remind hatchery staff to go to the incubators to check.
It connects by signal cables to each incubator or hatcher. When there is an alarm at the incubator or hatcher, like temperature alarm, humidity alarm, egg turning alarm, fan problem alarm, etc., the alarm signal will be sent to this alarm box, and trigger it.
Every incubator or hatcher has a signal indicator at this alarm box. So that when there is an alarm, the hatchery worker can know which machine has problem, and then go to the machine directly.
