Astec 63DV Call engineer 22

[Piotr]

I have an Astec 63DV alarm system. Fault light is on (22 call engineer). When the code is entered it displays "bell fault" and also "Sab". Please, tell me what is the reason of above faults. How can I repair it?

Hello Piotr.

SAB & Bell fault refers to the sounders that are connected to the control panel.

The fact that is showing both would suggest it is a wiring problem rather than both devices being faulty. Check the connections between the sounders bus at the control panel & the internal & external bell (SAB) . If these are on 2 seperate cables connect one at a time & see if either device works on its own. If one works then there is possibly a short circut on the second device. If there is just one pair of wires at the control panel then the SAB is wired from the internal bell. Connect the internal bell to this connection while leaving the connection from the internal to the SAB disconnected. Again it this works then check the cable from there to the external bell (SAB) for short circut. To check that both devices are working correctly bring both the internal & external bells to the control panel & wire them in on a short lenght of cable. These connections are polarity independent. If they both work there this would confirm a problem with the wiring. Check the wiring for continuity or short circuts.

Hope this helps
