Basics of Alarm Keypad Operation

In this video, Jorge explains the basics of alarm system keypad operation. Knowing how to use your alarm keypad and its various commands is crucial for getting the most out of your panel. You can use a keypad for basic tasks such as arming and disarming. It may also be used for advanced programming.

An alarm keypad provides an on-site access point for controlling a security system. For a hardwired system, you will need to add at least one keypad to the system. But for a wireless system, a keypad is largely optional. This is because the panel itself will typically serve as an on-site controller. However, you can certainly still add a second keypad for an additional on-site access point. This is great if you have a larger building where you might want to access your system from multiple locations. An easy example is if your house has both a front door and a back door and you want to be able to Arm and Disarm from both spots.

In order to communicate with an alarm system, a keypad will need to offer bi-directional communication. In other words, it must be capable of sending signals and receiving signals. This is unlike standard security sensors, which typically only need to send signals to the panel. The reason that a keypad must receive signals is because it must update the displayed status whenever the system is Armed or Disarmed. That way the user can check the keypad to see the current status for the system. This is why a wired keypad receives connections for both data and power when it connects with a panel. Wireless keypads send transmissions wirelessly, but they still usually rely on a plug-in transformer for power.

Keypads can also be push-button or touchscreen. Push-button keypads are commonly split up into two types. These are Alphanumeric Keypads and Fixed English Keypads. Of these two, only Alphanumeric Keypads can be used for deep-level programming. This is because a Fixed English Keypad will not display all the relevant text, However, you can still use a Fixed English Keypad for performing basic tasks like Arming and Disarming. Meanwhile, touchscreen keypads feature touchscreen controls and an AUI display. This is similar to what one would usually find on a wireless all-in-one (AiO) panel.
