280 Series Mechanical Heat Detector Recall

Review the below Identification Guide to help determine if you have an affected heat detector. If your unit is affected, please continue and register for a replacement.


Step 1: Locate Model and Date Code


To determine if the unit is affected, you must look at the following:

  1. Verify the unit is an Edwards unit (see question 2 to differentiate Edwards unit from competitor units)
  2. Unit must be a 135F model. Check "135" is printed on the side of the detector in large font.
  3. Date code must be newer than January 1, 2004. The date code is shown after the "135F" information and consists of 5 digits. The first two digits indicate the year, the other three digits indicate the day in the year. This number must be higher than 04001 to qualify as within recall scope.
  4. Optional: Unhook the detector from the ceiling and check the model number displayed in the product label on the back of the detector. The model number must be a model listed on the affected models table in the Tech Facts Documents (see table 1)

To remove the detector: Insert the tip of a screwdriver into the rectangular slot in the side of the detector base (see applicable mounting illustration for location of slot), lift the locking finger of the mounting plate, and turn the detector counterclockwise until it can be withdrawn from the plate.

Step 3: Verify your date code:


The date code consists of 5 digits (YYDDD) where YY = last two characters of calendar year, DDD = Ordinal/Julian number of the day of the calendar year. The date code has to be higher than 04001 (January 1, 2004) for the detector to qualify as within recall scope.
