UTC Technologies, which manufactures the Ziton range of fire alarm systems, has recently released an update on the life expectancy of Ziton fire alarm detection devices.

Most point-type fire detectors manufactured and distributed by UTC Fire & Security have an estimated working life of around 10 years when used in dry, non-corrosive atmospheres and if they are regularly inspected, tested, and maintained in line with manufacturers guidelines.

Detectors may continue to operate within specification after 10 years of service if in clean dry atmospheres due to intelligent design and programmed software recalibration, but gradual deterioration of integrity and reliability is eventually inevitable.

UTC’s latest update now states that:

“In the interests of safety and the avoidance of unwanted alarms, UTC is recommending the routine replacement of detectors after 10 years of continuous service”.

What next?

The age of any detector can be determined by the serial number or the date code printed on the product label, however, not all products use the same date code or serial number formats.

Any detector that is Ivory in colour is already 10 years old, as UTC changed the detector colour to Polar White in 2011.

Gavin Rees – Company director states “T. J. Fire & Security will be happy to check your devices at the next service so you can plan the replacement of devices that have exceeded their life.  We will always ensure our customers continue to meet legal compliance and maintenance requirements as per the manufacturer’s guidance”.
