Notifier FMM-1 Monitor Module by Honeywell, White Cover and EOL Included, Clean
This is a used monitor module removed from service in May 2026 there were no problems at the time of removal. There’s a white cover with two screws and a 47K resistor included. Please let me know if you don’t need the cover or if you need a different color cover. I have some light grey covers also. I have several of these units available. Please let me know if you need pictures of the other units. They are all in very similar cosmetic condition.
