Title: Life span of AFD
Post by: BHCC on February 20, 2008, 12:04:04 PM

Can anyone tell me the recommended life span of AFD? I am sure somebody told me that it was 15 years but is there a different period for ionisation and optical?

Thanks in advance

Mark

From Apollos website.

"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."

I have heard (but can't find) that Hochiki/Nittan say 15 or even 20 years.
