Request Smoke Detector Inspection Online

By Registering Online you will be able to printout your 26F Certificate from home or the office. This is the certificate required by banks to pass real estate papers.

Inspections are done 9:30 AM – 10:30 AM Monday –Friday excluding holidays. Please select 3 dates at least 14 days away that you can be available for the inspection. You must know if the residence is connected to a central station alarm company such as ADT. If so, a technician from the alarm company must be present. Failure to have the alarm company there will result in immediate failure of the test. Below are additional guidelines and a link to the State laws governing smoke and carbon monoxide requirements.

The State has issued new guidelines regarding the inspection of smoke detectors and carbon monoxide detectors for the sale of 1 and 2 family homes. One of the major concerns is the age of the detector. The homeowner is responsible for showing proof that the detectors meet the new code and are under 10 years old. If the homeowner cannot show proof and the detector appears to be over 10 years old – e.g., significant discoloration - fire personnel will fail the inspection. Fire Department personnel will not take down detectors to check the age.

It is highly recommended that the owner have their detectors checked before the Fire Department comes to inspect their residence. It is recommended that the homeowner replace any detectors whose age is uncertain. View the guidelines for meeting the law’s requirements (PDF)
