FireAngel ST-622 - Does Not Last
I have the FireAngel ST-622 with a battery date of Nov 2028. For the last year the alarm has been giving off intermittent bleeps; you reset it and sometimes it is ok for weeks, other times days. Tried to contact the company and no response. Have even tried FireAngel Safety Technology as I think they are a reincarnation of the original firm; no response
