How to Fix Issues on a Nest Secure Alarm System

Authored by: Support.com Tech Pro Team

1. Introduction

In This Guide

You'll Learn How To:

  • Correct basic problems with your Nest Secure Alarm System.

Before We Begin:

  • Make sure your Nest Secure Alarm System is set to Off.

2. Pro Monitoring Check

It is possible to have your Nest Secure Alarm System monitored by Brinks Security.

Faults or troubleshooting of the alarm system can be interpreted as break-in attempts, which will result in calls, and possibly visits by local law enforcement which may incur fees associated with such a response.

It is recommended to notify your monitoring company before performing any troubleshooting to avoid false alarms, or contact customer service for assistance.

4. Problem Check

Your Nest Secure alarm system does a good job of warning you if there are problems through the App.

Take a look at the Nest app to see if there's a specific error message being shown.

5. Pet Check

Pets are the most common cause of false alarms.

  • Pets that climb or fly.
  • This includes birds, cats, and other climbing animal companions. A cat jumping to a countertop tends to be enough to trigger most alarm systems.
  • Cats and other 'curious' pets.
  • Cats are curious creatures, and will tend to investigate the lights and sounds of home security systems. Between the rush of movement and vibrations this causes, a false alarm is virtually guaranteed.
  • Large animals.
  • This includes all animals over 40 pounds, regardless of type. A simple motion sensor has no way to determine if the moving object is a dog, or a person crawling and attempting to evade a lower-quality alarm system.
  • Pets of any type or size going up or down stairs.
  • The large amount of vertical motion will trigger most alarm systems.
  • Multiple Pets.
  • Multiple pets tend to play with each other, or otherwise interact. Most alarm systems will see this as one, larger moving object, and trigger the alarm.
  • Pets bumping the table the control panel is on.
  • The control panel will tend to have a suite of sensors inside, to detect when the device is moved, as well as simple motion sensors. The panel moving can trigger the alarm.

8. Other False Alarm Sources

Many alarm systems will trigger because of environmental conditions, because they can be signs of attempts to tamper with the alarm.

  • Heat sources like electric heaters, heat vents and fireplaces.
  • Most control panels have rudimentary sensors to detect changes in heat, which can be interpreted as a person.
  • Cold sources like drafty windows, air conditioners and AC vents.
  • Again, the change in temperature may be seen as attempts to tamper with the system.
  • Curtains near windows that may move.
  • A vent or pet moving a curtain can easily magnify movement and trigger an alarm.
  • Direct sun exposure.
  • Not only can this cause a serious temperature difference, but it can heat up the delicate electronics inside quickly.
  • Party balloons left unattended.
  • As they drift, that motion will trigger an alarm.
  • Insects that may come very close to the sensor.
  • Wireless access points within six feet.
  • Most control panels do not have extensive shielding, and the excess interference can cause problems.

10. Re-connect Power Cable

These errors happen when the Nest Guard has been disconnected from power.

  1. Unplug, and reconnect the power cable to the back of the Nest Guard.

11. Wi-Fi Connection Lost

This message happens when your Nest Secure cannot connect to Wi-Fi.

This can happen if you've recently changed your Wi-Fi Password, switched to a new Wi-Fi router, or the Wi-Fi router does not have power. It can also occur if you've recently moved your Nest Secure or Wi-Fi router, and they are no longer in range of each other.

Use these steps first, to power-cycle your router and Nest Secure.

Power-Cycle Router

  1. Unplug the power cable from the back of your Wi-Fi router.

  1. Wait ten seconds.
  2. Plug the power cable back in.
  3. Wait three minutes for the router to start back up again.

12. Connect Your Nest Secure Alarm System to Wi-Fi

We have a separate guide to help you get your Nest Secure connected or re-connected to Wi-Fi.

13. Relocate Router Check

Your router may need to be relocated to a more centralized location in order to provide better coverage for all your devices.

Bad Placement

14. Router Relocation

Since this appears to be a range issue that can be resolved by putting the router in closer proximity to the device's intended use area, we recommend moving the router to a more centralized location.

15. Range Extender

If wireless signal is not reaching your device, and relocating your router or the device itself to be in closer proximity is not possible or doesn't resolve the issue, a great way to boost wireless signal without replacing existing equipment is to acquire and install a range extender. Range extenders work with your existing wireless router as a type of wireless repeater used to expand the reach of wireless signal in your home.
