Hello,

Yes, the 330L was discontinued a long time ago and at this point all of your detectors are well beyond their expected life span and need to be replaced. You can consider using a combination of 9120BA smoke detectors and SC9120BA Smoke/CO combination detectors. You will need to replace both the mounting bracket(two screws) and the wiring harness/plug (connected by MAR connectors to your 120V wiring. The new detectors include both a mounting bracket and correct wiring plug.
