I have had this happen on a 3500 and I had to replace the keypad assy. But, you may want to try to restore factory settings just to see if it resets. Disconnect the battery pack and hold down any number key for 10 seconds (this bleeds off any charge that may be in the capacitors). Reconnect the battery and within 3 seconds, press and hold the "A" key. After hearing 6 beeps, release the "A" key and wait for 5 seconds for the lock to re-lock (listen for 1 beep and red LED).
If successful, this will reset factory settings, which means the master code is now 1 2 3 4 5. If you need a programming manual, go to At the top of the home page click on "support". Scroll to the bottom of the support page and click on Technical Library. Scroll down that page and find "trilogy DL programming manuals" and under that click on "download DL2700 enhanced instructions". I hope this is some help!

New smoke detector, new batteries, red light flashing is that normal

copied from the manual, available at the kidde website

RED AND GREEN LED INDICATORS This smoke alarm features separate red and green LED indicators. The LEDs indicate the following: GREEN LED CONSTANT ON - AC power is present. OFF - AC power is not present. RED LED - Can be seen through the Push-to-Test button. Blinks once a minute - Indicating presence of a working battery. Blinks once a second - Smoke alarm senses smoke and simultaneously sounds an audible alarm. Blinks once every 10 seconds - Smoke alarm is quieting an unwanted alarm (Model ADC only). (Interconnected system only): OFF - Another smoke alarm in the network has sensed smoke and is signalling this alarm.

Two of my smoke alarms went off (no fire/smoke in or near house), one has a green light blinking and one has a solid green light, which need a new battery/reset?

The constant green LED means the alarm has AC power.
A flashing green light every 2 seconds without an audible alert means the unit recently sounded ( was the one activated ) and is now in latching mode to let you know that it was the unit that detected the problem. To clear the latching mode hold down the test button for 5 seconds.
Red LED flashing once per minute means that the back-up battery is connected and functioning.
Red light flashing constantly during alarm means that it is the unit that initiated the alarm siren.

I have a factory installed alarm on my 2003 jeep cherokee ,how do i disable alarm

Hello! The drivers side door lock/unlock switch is more than likely defective...Having said that, the alarm system on Jeeps are a constant problem...To disable the system requires removing the drivers door panel and cutting the Light Green/Orange wire at the switch...And installing a 465 Ohm resistor...Not something done without the necessary skills...
I would have the vehicle towed to a Jeep dealer and have them test the drivers door switch and disable the alarm....Guru...saailer

I came home from vacation and the red LED was steady on. I replaced the batteries, and reset the master code. Everything seems to work, but the red LED is still on steady. How do I turn this off?

I have reviewed the installation and programming literature for the DL 2700 and there is no mention of circumstances where the red LED should stay on. For your convenience, I am providing the web link to Alarm Lock, the manufacturer of Trilogy, where I find the installation and programming instructions:

These links on this tech support page are in the format of PDF files. If they don't open for you, you need to install Adobe Reader first. You can get the free download for Adobe Reader here:

Concerning your problem, I would expect that the constant-glowing LED may drain the batteries over time and prevent your lock from working. I urge you to give Alarm Lock a call at this number
800-252-5625 during regular business hours (East coast) and request Technical Assistance.

I hope you are able to resolve this quickly-and inexpensively!

I connected 8, 100Ah battery with APC 2.2KVA inverter, now it doesnt give correct battery indication and keep producing beeping noise, whats the problem?

Continuous Beeping (theamber On Battery LED will be illuminated)

In order to protect the unit's batteriesfrom discharging too much, the UPS will shutdown and turn off its output. Towarn you that the unit will soon shutdown, the UPS will sound this alarm 2minutes before actual shutdown. With optional Powerchute Plus software, 2minutes can be changed to 5, 7, or 10 minutes to give you more of a warning ofimpending shutdown. If you hear this tone, you should immediately gracefullyshutdown your operating system to prevent data loss or corruption.
Note:This graceful shutdown will occur automatically if Powerchute PLUS software isbeing used.

Constant, Solid Tone (the red Overload LEDwill be illuminated)
This alarm indicates that the UPS has detectedan Overload condition. If this alarm is sounded, try removing non-essentialequipment. The alarm will remain until the load is reduced. To determine ifyour UPS is capable of handling the equipment you want to protect, visit APC'sSizing Guide at

Continuous Beeps for One Minute; RepeatedEvery 5 Hours (Replace Battery LED will be illuminated)
This alarm indicates that the UPS has failed itsSelf-Test of the battery. The unit will continue to sound this alarm until theunit passes the test. Try to let the unit charge for a few hours and thenperform another Self-Test (Press and hold the on/off button until the second'chirp', then release). If it fails and the unit is still in-warranty (twoyears from date of purchase), then contact APC. If the unit fails and its outof warranty, then order a replacement battey cartridge through your reseller,distributor, or from APC's web site.

Trilogy dl 2700 serries digital lock program managers code

First you need to know if you have a standard 2700 or the new enhanced version, it makes a big difference. Press any 2 buttons then star, if you get no response it is a standard version, if it beeps several times it is the new version. If it is the standard version, disconnect the battery and press any button. Now you are at factory default. Reprogram the master code, remember the master code and the operating code must b e the same length. 12345 A 1 A new master code A new master code. The master code is the only code that needs to be entered twice during it's programming. To set a manager code press; master code A2A new manager code, to set a new user code; enter master code or manager code A11A new user code. The programming must be done during the lock's unlock window so write down the procedure you intend to use to make things go quicker, if you need more time you can change the unlock window, it is probably set at the factoy 5 seconds. Press master code A45A4, this will give you a 20 second window to program the lock, when you are finished change the lock back to 5 seconds, press; master code A45A1, keep the open window short to conserve batteries.
