Where to find your model number and date code

The model number and manufacturing date code are printed on the label on the back of your alarm. Compare both identifiers with the notice above. A product photo alone does not confirm whether your alarm is affected.

Read the matching safety notice before removing an alarm. For the hardwired MPC122S, switch off AC power at the circuit breaker or fuse box first. Do not proceed with inspection while the green LED is on.
