If your SimpliSafe wireless security system cannot communicate with the Emergency Dispatch Center, it will let you know by announcing "No link to dispatcher" when you turn the alarm on and displaying "No link to dispatcher" on the Keypad. Also, the Base Station blue light will blink, indicating a warning.

Take the following steps to correct this condition:

1) Make sure you have activated your Emergency Dispatch Service online.

2) Move the Base Station near a window for better reception or connect it to a landline.

3) If you are using a landline, make sure the phone cord is securely connected to the wall jack and the Base Station, and that there are no other phones off the hook in your home. Also, if you need to dial "9" or another number to get an outside line, please add this dialing prefix using the Keypad menu (option 2) or Easy Setup Wizard (advanced options). If you do not need a dialing prefix, make sure none is set.

4) Occasionally, our nationwide wireless provider does not activate an account right away. We are automatically notified when this problem happens and will contact the carrier to resolve it, which may take up to 24 hours.

If the problem persists, please be sure to contact us.

Your SimpliSafe wireless security system monitors all of the sensors registered to it to make sure that they are operating correctly. If it cannot communicate with one of the sensors, it will warn you: the Base Station will announce "sensor not responding" and your Keypad will display "Sensor Error" and let you know the sensor # that is not responding.

There are several reason you might be experiencing this error:

• You haven't activated the batteries for one of your sensors. This is the most common reason for a sensor error for a system that was recently set up. All of the sensors in your system were preprogrammed into your Base Station before it was shipped to you. If you do not use one of the sensors and never activate its batteries, the Base Station will not be able to communicate with it. You can solve this problem by installing the sensor and activating its batteries or by removing the sensor from your system.
• The sensor's battery is not inserted correctly. Occasionally a sensor battery will be inserted in the wrong orientation or have a poor contact (perhaps some of the battery activation tab remained behind when you removed it). Please try removing and re-inserting the battery, making sure to orient it correctly .
• The sensor is too far from the Base Station. If your sensor and Base Station are very far apart, or if there is very thick wall in between, the wireless connection may not be strong enough. This problem can often be overcome by repositioning the sensor or moving the Base Station to a more central location in your home.
• The sensor's battery is too weak. When a sensor's battery approaches the end of its useful life its wireless signal strength may decrease. At this point SimpliSafe will start warning you that the sensor is not responding and you should change the batteries.
