Replace a battery on a smoke alarm

I have a fire alarm that is giving the warning beeps that the battery needs replacing, but I've been unable to do it. I need an electrician familiar with fire alarms to come and replace the battery - should be a very quick job. The make is HSSA-PE-FF / HSSA-HE-FF. Preference is for this afternoon before 6pm, or Saturday morning 9am-noon.
Turned up exactly on time, got the job done and explained what he'd done to help us in the future.
