Joel MorrisSomewhere in this house, a fire alarm is intermittently chirping to indicate it needs a new 9v battery, a sound seemingly only audible at 4am. Let battle commence.
Myles Winstone@joelmorris We have one that chirped in the early hours. Turns out it wasn’t pining for a new battery, it was the cold air affecting the sensor - which was why it didn’t happen during the day.
