Manual Pull Station Recall:
Manual pull stations that are the subject of this recall are manufactured of high impact ABS plastic and require a special key to reset. They are Edwards Model 274. The original service bulletin required a steel clip to be installed on the pull station door. When the door was closed (set in "normal" position), the clip fit around the head of the switch and would force it to operate when the station was activated (pulled open). The clip is no longer available and pull stations that are found to have not been retrofitted must be replaced.
6249C Smoke Detector Replacement:
GE Security is no longer manufacturing the 6249C (and family) of detectors. The listed replacement for this unit is the C2M-PD1. Do not use the C2M-PDC. The "C" in the latter, stands for the "Clean Me" option and will not work with a number of panels (such as 2280, 6500, 8500, and "SIGA" series smoke modules).
ESL-500 Series Smoke Detector Recall:
GE Security/Chubb Edwards is recalling 14000 ESL-500N Series Smoke Detectors Manufactured from June 2002 to June 2003. To view the complete list of affected units model numbers click HERE!
