How it works

Here’s what to expect when we take over your existing system

  1. Installation

    A full-time, fully licensed technician will connect the wireless transmitter to your system's main control box for a small one-time charge of $89.

  2. Signal Testing

    We’ll run a signal strength test, and send test alarms to our 24hr dispatch center to confirm success.

  3. System Codes

    Keep the same alarm codes if you'd like, or have new ones setup at no extra cost. We will train you on how to use it.

  4. Payment

    Your technician will accept payment for any necessary equipment charges (will have already been discussed and approved by you first).
