Difference Between a Control Panel and a Keypad

Using accurate terminology is crucial for developing a fundamental comprehension of your alarm system and evolving into an informed user. Grasping the distinction between the control panel and the keypad is essential for effectively utilizing the search feature in forums and formulating well-structured inquiries.

The phrases "control panel," "control," "panel," and "board" all denote the printed circuit board nestled within the metallic casing, or "enclosure," alongside the standby battery of the alarm system, as depicted on the left. Occasionally, external devices linked in close proximity that contribute to system operation are categorized within this grouping.

Peripheral components, encompassing protective loops and items like wireless receivers, printers, output devices, as well as end-user devices, do not fall under the classification of a "control."



A keypad, illustrated below, represents a peripheral device linked to a control. It serves as the user interface with the alarm system, facilitating the input of alphanumeric data into the system for activities such as arming and disarming, managing system functions, and programming. The keypad offers a continual display of system status information.

There are noteworthy exceptions to this standard. Certain manufacturers produce integrated keypad/control units, examples being the DSC SCW9047, the GE Simon series, and Ademco's Lynx panels, where the keypad doubles as the control unit. Additionally, there exist older, obsolete hardwired panels that exhibit analogous design characteristics.
