Can any please help. I have a securit 700l (CK700). I renewed the battery as bought system a couple of years ago and never installed it (original died 1 hour after installation would no longer hold a charge or take one). Now installed the standby battery seems to be doing all the work. I have wired the PIRs to aux for LED and also to zones for trip. All tampers wired to 24 tamper. Key pad also wired as instructed to aux for power. All of the above works fine. Trouble is the battery which is only a day old seems to lose charge although recharges quickly and cells test ok. Although I have 240v going in the output without the battery connected is only 1.5v DC, is this normal? I would have expected the 240v to output 12v DC and power PIRS using battery as a backup. If anyone can make sense of this please advise. The manual does indicate PSU output 12v Nom. Bell battery was also flat before install and has went flat a few times during testing (neighbors not happy) I understand that the internal bell battery would be taking a charge as well as led supply indicator. All works and responds fine other than the power issue.
