Security & Fire Protection Systems/Dicon System Inc 330L Smoke Detector

My 330L alarms also alerted during the night for no apparent reason. I had to remove all 3 of them before they shut off. They are all hard wired into the house. There is no battery backup for any of these units ? Didn't know they were carbon monoxide detectors ? They are 24 years old. I blow them out with air from time to time. Can't believe there is no reason or fix for this problem ?
