Why should I monitor my security system?

Alarm monitoring is quick and provides detailed communication between your home security system, and the central station of your security provider. Your control panel registers an emergency event and sends a signal to the central monitoring station, where the appropriate authorities are notified and sent to your home.

Who is my monitoring company?

Sellhorst installs your system, and National Monitoring Center (NMC) is your 24/7 monitoring company. NMC is a premier, third party UL monitoring company, located in California with a redundant location in Texas. You can contact them at 844.216.3973. Learn more.

How do I test my alarm system?

We recommend monthly testing of your alarm. Call NMC at 844.216.3973 to place the system on test. Make sure you have your password to do this. Once placed on test, arm your system and trigger an alarm. After the siren sounds, wait about 30 seconds, then disarm. Call NMC back to verify the signal was received. You will be asked to provide your password again. It is your responsibility to make sure your system is in good working order.

How do I schedule a service call for maintenance on my security system?

Please contact the Sellhorst Office at or call 402.504.9527 between 8am–5pm. If you need emergency assistance after hours, contact NMC at 844.216.3973, and you will be put in contact with our on-call technician.

How do I update my contact list?
