Error Beeps: Smoke detector warning signal beeps

Possible cause: Block battery is discharged or needs replacement.. Carefully twist the smoke detector's cover anti-clockwise until it comes free of its mount. Remove the old block battery and unclip it from the pins. Clip on a new 9V (type 6F22) block battery, making sure the pins click properly onto the poles, then fit the battery into its container. Line the cover's lock holes up with the locking pegs and turn it clockwise until it locks back into the mount.
