Powering down your Honeywell alarm system is a simple process that can be completed in just a few steps. Follow our guide to learn how.

Preparing to Power Down

Before you power down your Honeywell Alarm System, you must first prepare the system for power down. This includes disabling all sensors, triggering a panic alarm and checking to make sure the system is disarmed. Once all of these tasks have been completed, you can then proceed to power down the system.

Make sure the keypad is unlocked

Before you begin powering down your Honeywell alarm system, it is important for the system to be in “Ready” mode and for the keypad to be unlocked. To enter Ready mode, you must enter your alarm’s master code into the keypad; this will disable any errors or alarms that may have been activated previously. Once in Ready mode, you must then press “OFF” or “DISARM” until the keypad beeps and unlocks. If the system light is solid green, then your keypad will already be unlocked and no further action is required.

Make sure the system is armed

In order to ensure the proper deactivation of your Honeywell Alarm System, you must make sure that it is armed by engaging the system’s locking mechanism. To do so:

1. Press and hold the “Status” to enter your user code.
2. Enter your designated user code, followed by the “#” key.
3. Press “Away,” “Stay,” or “No Delay” on the system’s main screen, depending on which type of arming you would like to use.
4. After you have engaged the locking mechanism of your Honeywell Alarm System, proceed to power down the system using one of its two power down options according to your preferences and needs – scheduled or manual power down mode.

Powering Down the System

Turning off your Honeywell alarm system is a simple process that requires you to locate the main control panel , find the power switch and then turn it off. You should make sure that the power switch is in the “Off” position and the system is no longer powered. Let’s look at how to do this in greater detail.

Enter the Master Code

To power down your Honeywell alarm system, you will need to enter the master code assigned to the system. As with all codes, this one should be kept confidential and secure. Once you have entered the Master Code on your keypad, the Ready light will turn off and your Honeywell alarm system is now powered down.

When initially setting up your Honeywell alarm system or adding a new user, you may need to enter other codes as well. These additional codes are intended for authorized users only. The master code has complete control over all settings and preferences of the system and allows users with proper access to make changes such as entry codes, resetting troubleshooting events and settings arming peripherals.

It is important to remember that though you can manually power down the alarm through entering of your master code, it is still highly recommended that you arm your alarm when not at home by using an entry delay or a two-way touchpad notification device. Doing so ensures that if anything unusual were to occur while away from home, proper notifications would be sent out accordingly in order to prevent any potential damage or danger.

Select the Power Down option

In order to power down your Honeywell Alarm System, you will first need to access the Options Menu. This can be done by pressing and holding the [Status] button for 5 seconds. Once the menu appears on the screen, use your Volume and Function keys to select “Options”.

Next, select “Power Down” from the Options menu. At this point, a Power Down Warning message will display on your panel’s screen, informing you that any programmed outputs on loops 1 through 8 (if applicable) will be deactivated. If you wish to proceed with powering down your system press [OK].

If activated, an End of Line resistor (EOLR) must also be disconnected before powering down. This is indicated by a scrolling message across the panel’s LCD display stating “K3-EOLR Open?” If this occurs choose [Yes] if it is removable or [No] if it is not removeable. If in doubt select ‘NO’ and continue further.

Once complete, the system should power down within a minute or so after the disconnect button has been pressed and all programmed output loops have been deactivated. Your alarm system is now successfully powered down!

Enter the Power Down Code

Before you can power down your Honeywell system, you must enter the Power Down Code. This code is unique to your system and cannot be guessed. To find the Power Down Code for your system, locate the Honeywell System Manual. The manual should contain information about entering codes into the System Keypad. If you do not have a manual, please contact a local Honeywell authorized installer to obtain the necessary codes for your system.

Once correct access is granted with the correct Power Down Code, select Trouble/OFF Mode on the System Keypad to power down the system or enter a Bypass on any zones or sensors that will remain active during this time. After making all necessary changes while in Troubleshoot or Bypass Mode, press Stay/OFF (depending on model) to return alarm system back to normal operation mode and complete the shutdown process.

Finalizing the Power Down

The final step in powering down your Honeywell alarm system is to confirm that all system power is off. This includes all components of the system, such as backup batteries, keypads, and any external peripherals. It’s important to power down the system correctly, as this will help ensure that the system is fully deactivated and that you do not encounter any unexpected errors upon start up. Let’s go through the process of confirming that all components of the system are off.

Wait for the system to power down

Once the system’s main power supply has been disconnected, it is essential to wait for the charge to dissipate, which can take up to 30 minutes. During this time, the system will gradually shut down any active circuits and standby power will be drained from the backup battery. Once all power has completely faded away from the system, it is possible to modify codes and reset features of the Wired Alarm. Upon completion of these steps, reconnecting the main power supply completes the Honeywell Alarm System Power Down process, allowing for different Types of Alarm. to be set.

Check the system status

Before powering down your Honeywell alarm system, it is important to check the system’s current status. All components of the system, including connections and wiring, should be checked to ensure they are functioning properly and that the alert is not active.

You can check the system status by pressing the Status button on your Honeywell Control Panel. This will display an overview of all zone states, as well as other important information about the system’s current status. If anything appears out of order or a warning light or message appears, be sure to take care of this issue before powering down your system.

For added safety, you can also have one of our professional technicians inspect your home security system in person to identify any potential issues before power down.


When it comes to powering down your Honeywell alarm system, there are several troubleshooting steps you can take to make sure the system is shut down properly. This section will cover all the troubleshooting steps and their corresponding solutions to ensure your Honeywell alarm system is powered down correctly.

Check the batteries

When you’re troubleshooting your Honeywell alarm system, it is important to first check the batteries. Batteries should be replaced at least once a year or more often if your system has been experiencing false alarms or sensor issues. If the batteries are not replaced, the alarm could go off unnecessarily, resulting in unnecessary police dispatch. To check the battery life, locate the battery compartment door on your control panel; use a screwdriver to open it and look for a low battery indicator. Additionally, if there are external sensors connected to your system make sure to also check their batteries as well. Make sure all terminals are clean and free of dirt and rust before inserting new batteries. Once you have checked and replaced any low batteries, reset he system by pressing the “Reset” button on your controls panel or remote control device. This will cause any malfunctions in the system to reset or clear. If that does not solve the problem, contact Honeywell customer support for further assistance with your alarm system.

Check the power source

Before attempting any troubleshooting, it is important to check the power source of the Honeywell Alarm System. Look for the label on the control panel that indicates the type of power supply being used. This will determine how you will be able to properly shut down your alarm system.

The most common types of power supplies are battery operated and standard plug-in units. For battery operated supplies, unplug or disconnect them from the wall and remove all batteries from their casings. This will ensure that all power is removed from your system.

For plug-in supplies, make sure to unplug them from any AC outlet nearest to your control panel in order to remove power. Once these steps have been completed, proceed with other troubleshooting methods such as resetting the default settings or factory resetting the system if needed.

Contact a professional for assistance

If, after attempting the manual power down method for your Honeywell alarm system outlined above, your system still does not shut down and you have exhausted all other troubleshooting methods, it is best to contact a professional. An experienced security professional will be able to use a variety of specialized tools and test equipment to identify the root of your Honeywell alarm system’s operational failure and restore it back to normal operation.

Before you call in a professional, however, be sure to first check the manufacturer’s website or user manual for troubleshooting tips, or search online forums for authoritative DIY solutions from experienced users. It is also important to create (or retrieve) a copy of all applicable user manuals related to the alarm system in advance so that you can provide detailed information about its make and model number as well as setting parameters.

In addition to providing assistance with diagnosing and resolving issues associated with your Honeywell alarm system, a professional may also offer advice on how best to protect yourself moving forward. This could include tips on regularly inspecting any points of entry into the home as well as simple measures such as replacing outdated batteries or reconfiguring exterior lighting components so they are better suited for security purposes. A qualified security expert can also provide recommendations concerning additional safety features that may benefit your particular home setup or regional environment.
