[Ticket Question] Scantronic 9651

[Secware]

Hi, I purchased a Scantronic 9651 from you in July. I have now noticed that in Eng Mode all IR and Panel tampers are taken out (as expected) allowing me to access the components, but having just taken the external siren cover off the bell rang immediately. It may be that this is correct but I was not expecting this (other panels I have installed eliminate all tampers in Eng Mode, inc the Bell). I would appreciate it if you could advice me if this is correct. Also, if it is correct is there a way to avoid the bell going off during maintenance of the system.

For your info I have fitted a Pyronix Belle to the 9651 panel as below.

Belle 9651
B- 0v
B+ 12v
BA OP1 (Bell)
STB OP2 (Strobe-)
BT TR
TF No Connection

I appreciate your help

It is correct as opening the cover tests the tamper switch, battery and hold off. Some low end panels overide this on entering engineer mode but this prevents sab tests
