I have just replaced a Flash Guard XL Plus with a Pyronix Belle Sounder fitted to a Pyronix Octagon panel. Flash-guard Belle 1 Tampout BT 4 Supply - B- 5 Supply+ B+ 6 Trigger BA 8 Strobe- STB Added link between TF and B- The speakers sound, the strobe works. the LED's flash and the anti tamper operates when the alarm is unset. If I put the panel in engineer mode and operate the anti tamper switch the panel does not register a tamper condition which is correct but the Belle sounder still operates which means the front panel can not be removed for testing without setting of the Belle internal alarm. Any suggestions would be appreciated. Thanks, Keith.
