You are in valet mode. It means the vehicle will lock/unlock but not arm the security system.

Open the door then hit lock then unlock and lock. Led will now turn off and work as normal.

HOW DO I REPLACE BATTERY ON FIREX FX1218


BATTERY REPLACEMENT Always turn off power to smoke alarm before replacing battery.
Replace battery at least once a year, or immediately when the low
battery signal sounds (a beep once per minute indicates low bat-
tery). Batteries should be replaced regularly as necessary, even
when the smoke alarm is receiving AC power.
Use only the following batteries as replacements in this smoke alarm: Eveready 216, 522, 1222, Duracell MN 1604, or Ultralife U9VL-J [Alkaline batteries 9Volt] DO NOT USE RECHARGEABLE
BATTERIES.

1. Turn off power to smoke alarm at main service panel.
2. Turn smoke alarm counter-clockwise to detach from mounting plate.
3. Gently pull down smoke alarm. Be careful not to separate wire
connections.
4. Pull out power plug from back of smoke alarm.
5. From back of smoke alarm, lift tab to open battery pocket door.
6. Remove battery from pocket. Disconnect and discard bad battery from battery connector.
7. Connect a fresh, 9-volt battery to connector. The battery will fit
only one way. Be sure battery connector is securely attached to
battery terminals.
8. Place battery into battery pocket.
9. Close battery pocket door. Push down until it snaps into place.
10. Replace connector plug. Connector will "snap" into place.
Gently tug connector to be sure it is attached properly.
11. Reattach smoke alarm to mounting plate by turning smoke
alarm clockwise until it snaps into plate.
12. Turn on power and test smoke alarm using Push-to-Test button

Trying to jump start the car once the cables are connected the alarm comes on and I unlocked the doors with the key.


On my 94 Sovereign there is a switch inside the centre console that will switch off the alarm, not sure about the 96. You could try locking all the doors. connect the jump leads and then unlock the doors (the bonnet switch for the alarm I think is the same one for the under bonnet light so you might have to tape it down whilst the bonnet is open, just to confuse the alarm )

Good luck

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.

                Hi
                Before Battery Change

                • When was/or when did you notice alarm green light illuminated?

                • When after alarm was disarmed, did green light shine?

                First thing to check would be electrical connections starting from the battery.
                1. Follow positive wire lead from battery to fuse box connections. (Should be along driver side frame rail, or near battery.)
                2. Follow wrie harness to Relay Center. (Find Alarm Relay/Fuse)
                3. Also to Power Distribution Center. (upper driver corner engine bay)
                Relay Switch and Fuse to Alarm should be okay, given the alarm green light illumination.

                The Cars Brain, ECM Engine Control Module, manages messeges between power BattV and Alarm, also other modules and various sensors throughout the vehicle.

                When Battery Supply was disconnected, something happened, that stunned the memory in the ECM.

                Yes, the alarm does need resetting, its actually the memory messages saved in ECM need to be Refreshed.

                (saying "alarm needs resetting") sounds like alarm is broken, when that is not the case. Similar scenario is, when smart phone screen webpage freezes(alarm memory info in ECU). No buttons work, not even power button (Key Fob control). Only way to gain access is to remove battery.

                Lets try an experiment, this will be to loose still/saved frozen information, stuck in computer memory.

                How to Reset Vehicle Computer.

                1. Remove Neggative Post connection.
                2. Remove Positive Post connection.
                3. Let vehicle sit over Two Minutes, this time allows capacitors in vehicle Modules (ECM/PCM, TCM), to release any/all stored voltage, also any voltage in Vehicles ground circuit will be released.
                  • (I would typically wait 15 minutes) Capacitors with out constant Voltage input, will disipate rather quickly, depending on capacity size.
                4. With Battery Still Disconnected. Open Driver Car door, and turn Ignition to RUN Position.
                5. Reconnect Positive Post.
                6. Reconnect Negative Post.
                  • IGNITION is in RUN Position, when reconnecting Battery. Driver Door Is Open.

                  7. Turn Ignition to Off.
                  • Notice if alarm green light is illuminated.

                  8. Hit LOCK Button On Driver Door Switch to Reinitialize Alarm.
                  • Be SURE Key Fob not locked in car.

2001 mercury cougar can't get car to start alarm light lit and steady what do I do


sounds like your alarm is preventing the car from starting.

you can disconnect your negative battery cable, and wait about 10 minutes. put the key in the ignition and turn it to the ON position, but NOT to the START position. reconnet the battery cable CAREFULLY with the key ON, and the driver's side door OPEN. your alarm should "chirp" a few times, while reconnecting the battery. afterwards, try to start the car when the battery is tightly connected.

if the car still refuses to start, use the "panic" feature on your remote, to intentionally set off your alarm, and then turn it back off, to make sure it stops properly.

if this does not work, remove the fuse for your alarm, and try to start the car again without the fuse in place.....otherwise replace the fise and remove the pwoer connector from your alarm.

your actual alarm should be behind the trim plate, on the bottom side of your dash, above your gas and brake pedals....then try to start the car AGAIN....

if none of this works, then your alarm is defective and needs to be serviced be the installer, or manufacturer. also, calling the manufacturer will help too, as they have "reset and disable" features that can literally "bypass" your alarm.

ELANTRA ALARM PROBLEM


If the alarm keeps going off constantly and the remote has no influence on the alarm its most likely a connection problem. A hyundai dealer might be able to fix it but since you can start the car something you might be able to try is....
Check and make sure the remote battery is in the right way. Make sure all of the doors are closed, the trunk is closed, open the hood, connect the battery, close the hood all the way and try to lock and unlock the doors. Hope this works but if not, sorry it didn't work.

Alarm says terminals corroded



One of two things:

Somewhere in the wiring you have a weak connection and it is interpreting it as a bad battery or corroded terminals. It could even be where the cord goes into the sump pump. You will have to search it completely to find it.

The alarm itself is bad.

you might have to replace the batteries in the remotes. The reason why the alarm is going off because once you plug power back to the alarm brain it sets the alarm off and the only way to make it stop is to hit the unlock button the remote. Make sure all connections on the alarm brain are good and try changing the batteries in the remotes. also might have to reprogram the remotes to the brain if it has been sitting for awhile.
