do the call buttons indicated when the battery is getting low? so you know when you need to change the batteries?

Dear Customer, Thank you for your question. When the battery of the call button is in a low battery state, there will be no flashing indicator light prompt. When the button is dead, you need to replace the battery according to the accompanying battery replacement instructions. Hope my answer can help you. Have a nice day.

Can this be installed outdoors?

Dear Customer, Thank you for your question. This Strobe Siren Alarm needs to be connected to the power source. And it uses the rechargeable battery. When the power goes out suddenly, if the Emergency Strobe Siren Alarm is fully charged, it can last for about four hours in the standby state of the product.If you have a power supply that can be connected outdoors, you can use it outdoors. Hope my answer can help you. Have a nice day!

Could I set up 12 alarms and 12 buttons? So that any 1 button would activate all 12 alarms?

Dear Customer, Yes, it is ok to set up 12 alarms and 12 buttons. The emergency strobe siren alarm can max be paired with 20pcs button pagers. After you successfully connect 12 call buttons to 12 emergency strobe siren alarms (Each button needs to be registered with 12 alarms once), when you press one of the buttons, all alarms will be activated. Hope my answer can help you. Have a nice day!

Where do you get replacement rechargeable batteries for the main unit?

Dear Customer, Thank you for your question. The rechargeable battery is included in the siren and you don't need to buy batteries separately. Hope my answer can help you. Have a nice day!
