The ADT Key Fob is ADT's rebranded version of a Honeywell 5834-4 Key Fob. It functions in the same way as a 5834-4. It is also programmed with a security system in the same manner. The key fob features four distinct buttons. These buttons allow for system arming, system disarming and sending distress signals. A different loop number identifies each button.
The device can also function as an eight button key fob. Simultaneous button presses allow for these extra functions. A different programmed serial number identifies these simultaneous button presses. The enrolled serial number will be the same as the regular one, only with a "1" added to the end. This provides the device with greater functionality and versatility.
Many former ADT users bring their old key fobs with them to new monitoring companies. This is because they function exactly like 5834-4 Key Fob devices. Any panel that will accept a 5834-4 will also accept these key fobs. They are both seen as Honeywell 5800 Series devices that operate at a wireless frequency of 345 MHz. Any Honeywell or 2GIG alarm system can function with one of these devices. For that reason, they are usually recognized as Honeywell 5834-4 Key Fobs.
The recessed buttons on a 5834-4 Key Fob help to prevent false alarms caused by pocket presses. A user must press a button for at least one-half of a second for the device to activate. Two LED lights at the top of the device shows its security mode. A green light is for standard mode, and a red light identifies high security mode. If no light flashes, then the device has a low battery. The key fob will need a new battery about every three to five years. The device uses a 3-volt CR2032 coin battery.
Deleting a 5834-4 Key Fob from its old system is not necessary when programming it to a new one. The device will work with more than one alarm control panel if desired. That said, many users will take the time to delete a 5834-4 key fob from their old system. This prevents the key fob from controlling the old security panel.
Most users program a 5834-4 Key Fob as an Unsupervised Button RF. This will prevent a trouble signal from occurring when the device is out of range. Doing this allows a user to take their key fob with them when they leave their home. When they return, they can then disarm their system with the press of a button. This is very convenient for end users who want a quick way to disarm their system.
