Question about Ademco 5828 Wireless Keypad Lynx / Vista Non Talking

1 Answer

I have a Lynx system with a 5828 wireless keypad that I have connected a 5v transformer to it to keep the keypad lit always. The keypad does not stay lit always and it keeps going to sleep after 10 seconds. Is there something else besides connecting a transformer to it to keep it lit always. Thanks for your help!!

It sounds like your 5V transformer isn't working. It could be the outlet it is plugged into isn't working, or the outlet is on a light switch that is turned off, or there is a problem with the keypad itself. The user manual says:

"AC-Powered Operation: When powered by the
optional AC adapter, the keypad remains active at all
times. If AC power is lost, the keypad reverts to
battery-powered operation until AC power is restored
On AC powered units you can get the status by viewing
the display."

The only way I know of to keep it active is by using the transformer.

Hope this helps.

I need to replace my Honeywell ademco keypad M6674 Rev A. I have a vista 10 control panel. What model do I replace it with?

I am not familiar with this keypad, but if it were me, I would look to upgrade the control panel to a Vista 20P, although it's a bit involved...which keypad to use as a replacement depends on whether the current unit is wired or wireless. For wired, a 6150 or 6160 is appropriate, wireless perhaps a 5828 would be might get a better answer by contacting Honeywell directly.

My 5828V do not go to sleep after I change the batteries a few days ago. Please help

Is the 5828V connected to an A/C adapter? If so the screen will stay lit - this is normal. If you do not have an A/C adapter - try an arm/away then a disarm and see if that makes it go to sleep. ... and if you don't have an A/C adapter - consider getting one as the keypad will then report on system changes - something you are missing with a battery only powered 5828V.

I know on the Ademco Lynx-Plus keypad / the alarm panel - the display will stay lit after you exit programming mode until you do an arm/away and disarm so it may be the same with your 5828V.

Does the keypad go to sleep

Almost certainly yes, or it would use up the battery in no time...if you need a wireless keypad that can chime or be on all the time, see if this unit has the ability to have an external transformer, or look into getting a 5828 with an external transformer...the only time the unit will go to sleep is when it loses external power for some reason...happy hunting!

My lynx plus panel beeps and shows "30 check". What is that and how can i clear it? I cannot arm the system while that is up. Thanks for help.

It means that zone 30 is in a trouble state, possibly due to the cover being loose/off or a dead battery.

Press the asterisk (*) button two times and it will hopefully tell you what zone 30 is. Find that point and check the sensor. If the cover looks fine, take it off and put it on again. Try to reset the keypad by disarming it twice (enter your code then press off, do that twice).

It if still shows "check 30", replace the battery. Take out the old one and leave the new one out for at least one minute. When the cover is back on, try to reset the keypad by disarming it twice.

If that doesn't work, you should be able to bypass that zone by entering your code, then press bypass (the 6 button), then 30. So code+6+30.

It will stay bypassed until you disarm the system again.

How do I change the battery for alarm keypad?

Most keypads are using a 4 wire conductor coming from the security panel. If you have a wireless keypad such as a 5828 should be 3 to 4 AA batteries and as simple as removing the screws from the access panel in the back.

Lynx plus once a zone is in fault im unable to clear it

if its in fault you wont be able to clear it. the best you can do is bypass the zone until you can get a service tech out to it. put in your code, then the number six for bypass, then the two digit zone cone. it will allow you to bypass the zone and arm it each time until it is fixed. the only other option is to completely delete the zone and render it usless until its fixed. you can do this by entering program mode using the default 4112 then 800 or the last fout of your acct # then 800 normally. if that doest work, open the keypad disconnect the backup battery (usually green in the upper lefthand corner attached with a red and black set of wires.) and power down the system all together, then power it back up. the safest way is to unplu the transformer but if its in a wierd spot like the attic you can simply unscrew a wire from the black terminal block, be careful not to touch the other wire or your transformer will blow. once powered back on, when the system fist beeps, press # and * at the same time, it will say installer code. you can set it to what you want, i always use 4112 (system default) once in main programming, hit *56 to go to zone programing, then hit the two digit zone code, then follow it with *00*1 that will totally delete the zone rendering it usless untill a service tech can be sceduled to add it back in. but, your system will be able to arm the rest of the house.

My 5828v still goes into sleep mode with ac power

My newly installed 5828V also thinks it is in battery mode all the time. The ADT tech found no 5 VDC at the plug coming from the basement. The installer had added wire to make the trip, so there were four splices. One of them had come loose. The ADT repair tech repaired the splice, but the keypad then failed entirely.

I wondered if the original installer had gotten the polarity backwards, but because there was the broken connection, the keypad was saved from destruction. (Operating on battery causing my symptom) When the ADT repairman fixed the splice, the wrong polarity condition may have blown the keypad.
