Yes fire alarms are in many cases are connected to building air conditioner systems, but before you decide your fire alarm has caused your particular problem answer this question. Have you had any problems with your building fire alarm system, or have you had any alarms or supervisory conditions with your alarm? If not, then you might want to look to other probable causes of your problem first. Be advised we have had customers that have indicated that their air conditioner repair company told them the fire alarm was causing problems with the air conditioning system only to find out that the alarm was not even connected to the unit with problems.
If you have or are having duct smoke detector alarms on your fire alarm, try the following to clear the alarm on the fire alarm. After clearing the duct smoke alarm, your air conditioner should operate normally.
- First you must locate the area of the detector in alarm.
- Go to the fire control panel. If it indicates an AHU number, and you don’t know where this unit is located, the best way to determine which unit duct smoke detector is in alarm is to walk around to the thermostats on the wall used to set the room temperature, and see if one seems to be off (Blank display, no power lights etc.)
- When you have found the AC unit, now you will need to find the duct smoke detector that is in alarm. This can take some time as most AC units can serve several thousand square feet of an area. Walk around the area served by this AC unit and look on the ceiling, and wall near the ceiling for what we call a remote test switch. This switch will be about the size of a light switch. See the examples below.
