Question
QUESTION: Hi, i have a DSCPC1555 alarm. it has been chirping every 10 seconds for 3 days and I am going mad from sleep deprivation. *2 brings up troublecodes "zone 1" bright and "zone 2" dull. suspect its a battery problem. no idea who installed. is it possible to turn the whole thing OFF just to get one nights sleep before finding a technician to come tomorrow at great expense? i can't work out how to open the front panel to remove battery or disconnect wire. HELP! thanks.
ANSWER: Hello Andrea, and thanks for writing.
To disable the alarm, you have to disconnect both the AC power and the backup battery (which is failing anyway). This is done at the control panel, not at the keypad. The control is usually tucked away in a closet. When you find it, open it up. You'll see the battery in the bottom. You'll also see a circuit board with a row of terminal connections at the bottom.
Disconnect the first wire from the left; tape it with electrical tape so it does not short out. It's 16 volts, so no need to worry about shocks. Next, disconnect either the red or black wire from the battery. That's it.
When you get a replacement battery, just plug it in (red is positive and black is negative), and reconnect the wire to terminal one (first from the left).
Best Regards,
Dave

QUESTION: thanks. do you know the product type/code for the battery? crazy that this isn't on the user guide.
Answer
Happy to help...
The battery in your control should be a 12 volt, 4 ampere hour, sealed-lead acid type, like this one: http://www.batteryprice.com/bp4-1212v4ahsealedleadacidbattery.aspx
However, depending on the equipment that you have in your system, you may have one with a larger capacity (meaning that the ampere hour rating would be higher. If you take a look at the battery in your control, this information should be printed on the battery).
If you Google "alarm battery", you'll find there are many vendors and different brand names for these batteries. You don't have to get the same brand as the old one. The important thing is to match the voltage, ampere hours, and battery type.
I hope this helps, and please write again if you have any trouble.
Best Regards,
Dave
