Dave Walton Posted April 15 Share Posted April 15 Evening all. I have a very old but very reliable ADE Optima 2 Plus 8 zone alarm system that I installed some 30+ years ago. Problem is I would now like to add another keypad to the system (Two fitted at present) and the chances of me getting my hands on one is more or less zero ! (Already looked on Ebay, etc) So, two questions for the good folk on here, first the long shot.......Does anyone by any chance have a Optima 2 plus keypad lurking somewhere in the depths of their van, garage, loft, etc, etc, that they'd like to sell me ?, and two, is there an alternative keypad that I could use on this system, and if so, which one is it ? FYI.....I've attached an image of the type of keypad in question, the connections on the keypad are as follows K1 - K2 (Tamper) K3 - K4 (- & +) K5 - K6 (Data) If anyone on here could help me out, it would be very much appreciated. Regards, Dave Walton. Link to comment https://www.thesecurityinstaller.co.uk/community/topic/47203-alternative-keypad/ Share on other sites More sharing options...

sixwheeledbeast Posted April 15 Share Posted April 15 You say it's reliable but I'd be amazed if it actually charges the battery properly.... I'm all for looking after things in good working order but most ADE stuff I come across is no longer FFP.

I have removed the old battery and plan to replace it once I've finished doing the few little alterations I hope to make. Checked the voltage at the panel outputs for the battery and was getting 14.6 V. Regards.

sixwheeledbeast Posted April 15 Share Posted April 15 Oh so the PSU is cooked then... Link to comment https://www.thesecurityinstaller.co.uk/community/topic/47203-alternative-keypad/#findComment-529085 Share on other sites More sharing options...

My comment stating 14.6V at the panel battery connections was intended as for information for the more knowledgeable on here to perhaps tell me one way or the other if the panel is working correctly, and not in any way that, in my opinion, this area of the panel was ok. (Hence the reason I'm in the DIY installers forum !) From your reply I would assume that the PSU is actually not working correctly, if this is so I'd appreciate it if you could perhaps elaborate a little so that I could better understand this issue and therefore learn something. I'm always grateful to anyone whom is more knowledgeable about these things than me that takes the time to reply in an effort to help / assist. Regards, Dave Walton.

sixwheeledbeast Posted April 16 Share Posted April 16 Aux voltage should be around 13.6Vdc. 14 or more is too high it's likely the voltage regulator is failing. They sometimes have adjustment controls to set voltage lower on the 317 but even so I imagine it's tired and can't push enough amperage to fully charge a battery after a power cut. Most ADE stuff this age is like this and should be considered for upgrade. Modern stuff uses switch mode power supplies and while more complex use a lot less energy over there life.

As you've mentioned aux voltage, I'd like to provide a little more information. There is a block of six terminals grouped together on the circuit board all related to power, two for the connection from the transformer, they measure 18.34 VAC, two for the battery connections, they measure 14.27 VDC and finally two for the PIR's etc, they measure 13.58 VDC Hope the above are more helpful regarding the working condition of the power supply. (If this changes nothing, no bother, at least you now have the full picture to work with) Regards.
