At 6:58am local time, we had a fire alarm activation in our BOL8 datacentre. Our monitored alarm system automatically notified local fire services and they attended around 5 minutes later.
After thoroughly inspecting the affected area it was deemed a false alarm sensor activation.
The fire service advice was to reset the alarm and check that it did not reactivate. With a successful rearm of the system, they advised not to directly replace the sensor unless it gave a further false alarm.
No fire was detected, and there was no interruption to any services in the datacentre.
