Does the Firex Model No. FX1020 hardwired smoke alarm contain a Battery backup. I have three FX1020 alarms chirping. I removed (disconnected the wires) from one of the three FX1020 alarm covers but do not see where I can gain access to the interior of the smoke detector to see if their is or is not a battery within the unit.
