BAUERJAN Posted April 15, 2009 Share Posted April 15, 2009 Good evening to all. Last year we had a mains outage that lasted for nearly 24 hours - a burnt out transformer. My alarm system was in operation on the standby battery for this period. As the battery discharged, the outside Bellbox activated. The other evening something similar happened after a mains outage time of approx 2 hours. I presume the standby battery is finished. However, should the Bellbox activate under these conitions. Any help would be much appreciated. Regards Jimmy Link to comment Share on other sites More sharing options...

james.wilson Posted April 15, 2009 Share Posted April 15, 2009 as above the sounder thinks it has been disconnected from the panel, ie wire cut etc. As the panel is dead it cant tell the bell 'im here' basically its called a hold off signal. to hold off the bell. If this hold off disappears the sounder should activate. securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
