Help - Alarm System Issues after Power Cut

There should be a factory reset button or key sequence but that isn't a lot of help if you don't have the engineering manual for the unit. -- Regards, Martin Brown |

Thanks Phil Have you tried powering up without the battery connected. If its dead (or failing to charge) then it may be dragging down part of the rest of the system. How long ago was the battery changed? It may only have a reliable active life of 2 to 5 years. -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |

Thanks Alan Yes the battery was the culprit. Thanks for response and pls see my other post. From the behaviour of the panel and keypad I was seriously expecting that the power cut had created a spike and fried the panel board. An early Xmas present from Santa! |

I didn't realise Texecom have phone support but found the number. The tech guy on my model says this is a common reaction to power loss if the battery is shot. The solution was to disconnect the battery and power up the panel on mains only. Just need to dive out to Screwfix for replacement battery. Strangely when the panel was powered up, the keypad displayed a message about arming all zones, but this disappeared on input of my access code.

From the behaviour of the panel and keypad I was seriously expecting that the power cut had created a spike and fried the panel board. The other common problem with the battery is that after X years of being trickle charged it still has a acceptable terminal voltage but it cannot supply the instantaneous power on a power cut. This results in the alarm triggering at the instant of the power cut but the batteries then supply enough power for the alarm to stay sounding. -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |

I've picked a replacement battery up from Screwfix - open till 8pm which I didn't realise. So hopefully will be sorted tomorrow. This time I'll put the install date on the front of the panel as well as on the top of the battery Phil -- ----Android NewsGroup Reader---- http://usenet.sinaapp.com/ |

Has it got an internal battery for the systems settings? If this is duff then it will have forgotten them all and after replacing the battery, you may need to find some instructions about resetting it all up again.

I took a pic of the board when I was trying to resolve this afternoon's issues and have revisited that. Can't see a CMOS type battery. Can this info be held up by a capacitor and circuitry? It certainly accepted my access code, so I am hopeful all the config data has been retained. Phil -- ----Android NewsGroup Reader---- http://usenet.sinaapp.com/ |

Probably saved in non-volatile memory (Flash memory/EEPROM) that is accessed only on switch on and to write when a configuration changes. Don't forget that there is probably a NiCad rechargeable battery (stack) in the bell box. It purpose in anti-tamper and will trigger the sounder if the bell box loses contact with the controller (cut wires etc). This will also have a life expectancy of around 5 years. -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |

Imagine a long power cut with an empty house that had the alarm set by the owners just as they went on holiday. If the powercut is long enough so that the internal battery has time to discharge you would not want the alarm to start up in a non alarmed state when power is restored would you? But your 7Ah battery should easily do a few days without power. Most people have 2.1Ah batteries. -- Adam |
