Bosch/Radionics panels are designed to distinguish between a Low Battery and a Missing Battery. To test for a low battery the AC power would have to be removed and the panel left to run on Battery until the battery goes low enough for the panel to see that it is low. By removing the battery from the panel a MISSING BATTERY EVENT is being generated.
On a D8112 or 5505, these panels do not monitor for MISSING BATTERY, just LOW BATTERY. So if the battery is removed the panel does nothing. But if the battery voltage gradually falls below 12VDC a Low Bat event is generated. As long as line 28 BATSUPV is marked yes in the program. This can be found in the MAIN under the sub heading ACCOUNT NO/SUPERVISION.
On a D7212B, D7212B1, D9112B, D9112B1 5800B, 5800B1, 5900B or 5900B1 these panels have the ability to do both MISSING BATTERY and LOW BATTERY if programmed in the panel to do so. If the Battery gradually falls below 12.1 VDC, it will generate a LOW BATTERY EVENT and if the battery is removed it will generate a MISSING BATTERY. To program this go to PANEL WIDE PARAMETERS then to PHONE ROUTING then on the line that displays DIAGNOSTIC put a P. Then under PANEL WIDE PARAMETERS go to POWER SUPERVISION mark AC/BATTERY BUZZ and BAT FAIL/RES RPT as YES. This will cause the keypad to buzz and the report is sent to the central station.
On a D7212, D7212G, D7412, D7412G, D9112, D9412, D9412G, 5800C, 5800G, 5900C or 5900G these panels have the ability to do both MISSING BATTERY and LOW BATTERY if programmed in the panel to do so. If the Battery gradually falls below 12.1 VDC, it will generate a LOW BATTERY EVENT and if the battery is removed, it will generate a MISSING BATTERY. To program this go to PANEL WIDE PARAMETERS then to ROUTING then to DIAGNOSTIC REPORTS and make sure that BATT MISSING, BATTERY LOW and BATTERY RSTL all are marked as YES. Then under PANEL WIDE PARAMETERS go to POWER SUPERVISION mark AC/BATTERY BUZZ and BAT FAIL/RES RPT as YES. This will cause the keypad to buzz and the report to be sent to the central station.
If any of the panels beside the D8112 or 5505 are set up for fire and using a D192 Bell Supervision Module a situation can be created where the battery leads are removed and the panel does not generate a MISSING BATTERY EVENT. The programming of the panel has been checked and it is correct. This issue is created by hardware. On the D192 module there is a jumper marked 8112 or 7112/9112. If this jumper is in the D8112 position the panel will not see the missing battery. Put the jumper in the 7112/9112 position for it to operate normally on these panels. Please keep in mind the D7212G is not rated for commercial fire and should not be used as such so this problem would not exist on that panel.
