Why Does It Matter That Your Monitoring Is UL Listed?
UL (Underwriters Laboratories®) is a non-profit product safety certification organization that has been testing products and writing safety standards for more than one hundred years. By having your alarm system monitored by a UL Listed and approved Central Monitoring Station, you can be assured of the highest quality monitoring service certified by the #1 safety standard in the industry.
Do You Offer Fire Alarm Monitoring?
Your smoke alarm will help save your life, but our services will help save your property too! In a fire situation you should not count on bystanders or passers-by to call the fire department. Whether your building or residence is vacant or occupied, has a sprinkler system or not, let Security Instrument be your guardians. Seconds could mean the difference between minor damage and total loss.
Do You Offer Online Bill Pay?
Yes! You can pay your bill online by clicking here.
What if the power goes out? Will the monitoring center still be notified if there is a fire?
All fire and security systems installed by SI have battery backup. As long as the batteries are still functioning the security system should still send a signal.
Is there a charge for a sales consultation?
No, we never charge for a sales representative to review your site and provide you with a no obligation proposal for security, fire, video, or access control.
Do I own my system?
All residential security and fire systems are customer owned. Commercial systems can be customer owned or leased. Your sales representative can provide details on leased systems and how they may benefit you.
How do I update my credit card or banking information that you have on file?

I’m getting rid of my home phone line, can you still monitor my system?
Absolutely! We have a wide variety of monitoring options, such as cellular, radio, network, and Wi-Fi, that do not require a traditional phone line. These options include NFPA approved methods for commercial fire as well as residential systems. We can even utilize more than one type to provide you with redundant paths of communication for even greater levels of security.
I’m going out of town should I let you know?
Yes. We’d recommend contacting our central station and letting them know you will be out of town so they can make a note on your account. The central station can also assist you with setting up a temporary contact list in case someone needs to be notified of an alarm at your location while you are unavailable.

How do I change my keypad code?
Due to the wide variety of systems we’ve installed over the years we would recommend you call in to our central station at 302-998-2261 so they can identify the type of system you have and give you instructions for changing your keypad code. The central station will also help you test the code once it is changed to confirm it is working correctly.

What is the difference between a keypad code and a passcode?
Your keypad code is the code you enter at your keypad to disarm or arm your alarm system. This code is generally between 3-6 numbers. Your passcode is the alphanumeric code that our central station will request from you to identify you as an authorized person on the account so you can cancel alarm dispatches, update your call list, or request service. Many people have gotten away from using passcodes and have started using passwords or pass phrases that they select.
