How do I determine the age of an Apollo detector?

Since March 1981, each detector manufactured by Apollo has a date-coded serial number, the first four digits indicating the month and year of manufacture ie 1096 1234 shows that the detector was made in October 1996.

Detectors manufactured by Apollo which do not have a serial number can only have their age determined by referring to serialised records held at Apollo. The absence of a serial number would mean that the detector was made before March 1981.

Detectors manufactured by Apollo have a recommended working life of 10 years when used in dry, non-corrosive atmospheres and provided that they are regularly inspected, tested, cleaned and recalibrated as recommended. For further information, please visit our Cleaning & Recalibration page.

Most Apollo detectors will continue to operate within specification after 10 years' service, however, gradual deterioration of integrity and reliability should be allowed for.

In the interests of safety and the avoidance of unwanted alarms, Apollo recommends the rountine replacement of detectors after 10 years service.
