Hi, I need to extend a fire alarm, the panel is a CTEC CFP 2 zone one and currently it has a couple of apollo alarm sense sounder bases/heads on it. I fitted 2 extra normal (non-sounder) alarm sense bases and alarm sense heads but the panel is showing a fault on that zone, the fault clears if I bypass the two conventional base's. All the heads work on the sounder bases.
Are the alarm sense conventional bases compatible with the CFP panels because the instructions just show a diode base in the wiring diagrams, if they aren't then why do the alarm sense sounder bases/heads work ok.
Edit - I've just checked the CTEC site and it does say the panels are compatible with the alarm sense stuff. Why would it show a fault then if it clears when you bypass either base, they are definitely wired the correct way round. The bizzare thing is the panel still shows a fault if you put the end of line capacitor in the panel along with the fire alarm circuit if either base is in he circuit it that makes sense.
Edit 2 - I didn't get any instructions with the bases as they were just loose in the package but apparently you don't wire the alarm sense bases across L1 and L2, both browns go in L1. Fancy having an L2 connection then, its just inviting trouble, luckily they are only £3 each.
