Fire Alarm
Two friends have had the Fire Service install alarms without any problems so tried them (criteria being if over a certain age and smoker) last Friday, left message and just had a call this morning, appointment booked for 3rd October for survey and maybe install alarms, won't touch mains ones so will mean having double alarms everywhere. Apparently there will be a back-up battery in the alarms but cover says don't remove without switching off at mains? I have tried Googling but would prefer to hear from someone who has the same type of alarm if possible who might know. Many thanks.
