What's the difference between Entry Delay, Exit Delay, and Instant Trigger?
Your Entry-, Motion-, and Glassbreak Sensors come equipped with several modes that can help you with arming your system, disarming it, and triggering an alarm event the moment the sensor is triggered. Below you can learn more about what each mode does and how it impacts the usage of your system. Scroll to learn more, or use one of the anchor links to go to that section directly.
Entry Delay
When enabled, the Entry Delay is the amount of time between when a sensor is tripped and when the alarm begins to sound when your system is in an armed state. That way, you have time to disarm your system without the alarm immediately going off. Once a sensor is triggered, your Keypad(s) will begin to beep, indicating that the system is counting down to the predetermined time at which the alarm will sound.
The Entry Delay can be set anywhere from 0 - 255 seconds. The default setting for your system is 30 seconds. It can also have different settings for Home and Away modes.

4. Once done, click on SAVE at the bottom of the screen
Exit Delay
The Exit Delay setting is the amount of time allotted for the system to countdown and arm when you set your system to Home or Away mode. This setting is most useful for main entryways to your home, so you have time to arm your system and leave your home without setting off the alarm. By default the setting is 60 seconds, however, it can be set anywhere from 45 - 255 seconds.

How Does the Glassbreak Sensor Respond During an Alarm
Glassbreak Sensors are programmed to listen for the specific frequency of windows breaking. They're even sensitive enough to know the difference between a plate breaking, and a window breaking. Inside SimpliSafe’s Glassbreak Sensor is a small microphone that is calibrated to react to the sound of the glass being struck and then breaking. Pane glass has a certain sound frequency when smashed, which the sensor hears and then trips the alarm. The sensor is listening for the initial “thump” of the glass being struck, which in effect “wakes” it up, and the sound of the glass breaking micro-seconds later trips the alarm.
When a Glassbreak Sensor detects broken glass, the entry countdown will begin. This is dependent on your arming state and the alarm mode you set for it under the Glassbreak Sensors Settings Menu. The entry countdown by default is 30 seconds, however, this can be adjusted at any time within the SimpliSafe® App.
You can customise the entry countdown settings by going to:
1. Open the SimpliSafe® Mobile App on your phone or tablet
2. Select Device Settings
3. Choose your Glassbreak Sensor from the list of available sensors
4. Under Alarm Mode select your arming state and adjust the settings, as needed
If the system is disarmed within 30-60 seconds of the initial alarm signal, this will be considered a false alarm by our monitoring centre. That means you will not receive a phone call and if this is the only sensor that has triggered no guard dispatch will take place.
If the system is not disarmed before the time elapses, an alarm will sound. Depending on your monitoring service plan, two things will happen at once.
The Emergency Contacts for your system will receive a phone call from our monitoring centre to verify the status of your home.
If the alarm is not canceled within the grace period, the Emergency Contacts will receive a call from our monitoring centre. During this call you will be required to provide your Safe Word to the agent you speak with. Please note that providing the wrong safe word, or no safe word will result in a request for dispatch. You won’t be told you got it wrong to protect anyone who may be under duress. Additionally, missing the phone calls to your Emergency Contacts will also result in a request for guard services to the location that your system is registered to.
We encourage you to save the monitoring centre numbers to your phone. The numbers in which Securitas call you from:
- Securitas will contact you from: 0330 184 0444
- You can contact Securitas on: 0303 330 0369
- Test Mode Automated Call: 01908 644505
Once saved to your phone, you’ll also want to allow us access to bypass Do Not Disturb and Silent Profiles. This allows for Critical Alarm Notifications to get through to you, regardless of your phone’s volume or profile status.

Glassbreak Sensor Not Responding
The warning ‘Sensor Not Responding’ for a Glassbreak Sensor can be caused by a couple of things, including a low battery or a weak connection between the device and the Base Station.
As a first step, we’d recommend ensuring that the battery is correctly installed. To do this:
1. Slide the sensor off its’ bracket by pushing it towards the wall and up
2. Remove the battery from the Glassbreak Sensor
3. Wait 15 seconds, then reinstall the battery again
4. Then, test the Glassbreak Sensor by placing your system into Test Mode using your Keypad.
5. Press and release the button on the Glassbreak Sensor. The Base Station should announce “Glassbreak Sensor” and the timeline should show “Glassbreak Sensor Test” on the SimpliSafe Mobile App.
If you have replaced the battery and are still encountering the ‘Sensor Not Responding’ error, it likely is the result of a weak connection to the Base Station. A weak connection to the Base Station can often be caused by something environmental, like brick walls or dense home construction.
To test this, temporarily move the Glassbreak Sensor closer to the Base Station and see if the error stops. If the sensor does work in a new location, it is likely the result of the environment near the prior location that is causing the conflict. You’ll have two options from here; Keep the sensor in its’ new location closer to the Base Station, or try to identify and clear the interference in the sensor's existing location. If you choose to keep the sensor in the location where it has encountered the error, you’ll want to look for environmental factors, such as dense building materials, or wireless devices that are nearby that could be interfering with the RF signal between the sensor and the Base Station. If you have any devices that output a wireless signal, we recommend trying to keep them at least 3-5 feet away from your sensor. That should help to clear up communication between the device and the Base Station.
