User questions & answers

Question:	Can you have multiple strobes attached to one unit
Answer:	Yes, it is. I bought the batteries from another company and the batteries could last easily a year or more. A23 batteries 12 V here is the link: https://www.amazon.com/dp/B01C57SPQ6
Question:	can you set up to just use light but no sound or alarm
Answer:	I agree with the poster who said your doorbell must be set to the same frequency as the other classrooms. I had the same problem. Mine would go off and nobody would be there but I noticed my neighbor would have someone at her door. Then one day she asked me if nicely if my grandson was playing 'ring and run' because her doorbell would ring, nobody would be there but she'd see my grandson at my front door. It was then I questioned her and found out we both had the same doorbell and were on the same frequency. Once I changed the frequency, it stopped ringing when she got company.
Question:	How do you order extra receivers
Answer:	I don't think so, I bought this set https://www.amazon.com/Classic-Wireless-Doorbell-Indicators-transmitters/dp/B07D76P1C7 and so far I am very pleased, the transmitter is waterproof and you can add more receivers or transmitters
Question:	Can you add push buttons to the receiver
Answer:	I bought this set and so far I am very pleased, the transmitter is waterproof and you can add more receivers or transmitters https://www.amazon.com/Classic-Wireless-Doorbell-Indicators-transmitters/dp/B07D76P1C7
