Hello, I can help you with this. Is this just an intermittent chirping or a constant noise? Some things you can try are to replace the batteries and blow the dust out. They could be old enough where they need to be replaced. It is recommended to replace each detector every ten years.
If you can't get the noise to stop you can just unplug them from the connector. You would have no smoke detection alarm though.
Check power to them to make sure it is good. Then I would have them replaced since they are old. If they are interconnected then if one senses a sensor failure it could be sending the notification chirp out to all connected units.
I would go with this unit or something similar. You want battery backup in case of a power outage. https://www.lowes.com/pd/First-Alert-AC-Hardwired-120-Volt-Smoke-Detector/3031837
Something similar would be any 120 volt hard wired, inter-connectable (which means it will have three wires -black, red, and white), ionization type, smoke detector with battery backup. Photoelectric type are recommended in kitchens and bathrooms where steam and cooking smoke could cause false alarm.
You can buy these at any home improvement or hardware store such as Lowe's, Home Depot, Ace hardware, True Value, Do-It Right Center, RP Lumber, etc. Or a number of online retailers that will come up with a Google search.
