hi all i have a problem with my accenta mini g3 alarm. i bought a house and when it came to sorting the alarm out without knowing what i was doing the alarm went off but i had no reset code. the only way i could silence it was to pull the main fuse out. now ive got to the point where everything seems to be working appart from external bell. the control panel says everything is fine and when i do the tests the outside strobe works but not the bell. any help wud be much appreciated
