Leaving the house today and pressed the Set button on the Accenta Mini Gen 4 RKP, only to get an immediate beep, beep, beep from the external sounder. It was not the normal alarm sound, but certainly sound more like a warning noise.

Additionally, the red 'power' led on the RKP is flashing at around 10 second intervals. Unsetting the alarm, and the sounder beeping continues for around another 30 seconds.

Cannot find any reference to the issue in the manual but would appear to be power related. I will check the control panel fuses and the date of the back-up battery but of 'greater' concern is the back-up battery in the Reson 8 external sounder. It is a 6v Ni-Cad and has never been replaced in the 15 years since installation. (I only use the term 'greater' concern because that requires tallish ladder work to replace it.)

Presumably, the Ni-Cad should be replaced but the manual has no mention of a life expectancy.

Grateful for any thoughts or suggestion as to any other possible causes.

Thanks and toodle pip

PS. I have an mp4 and m4a sound files of this warning beep but am unable to attach. Does the forum not allow such attachments?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18358&Focus=309412#Comment_309412 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18358&Focus=309412#Comment_309412 Thu, 02 Oct 2025 17:59:35 +0100 revor
