Intrusion wired alarm system keypads, expanders, and power supply units (PSUs) are fundamental components that enhance the functionality, control, and reliability of security systems.
Keypads serve as the user interface, allowing authorized personnel to arm, disarm, and program the alarm system. Equipped with LCD or LED displays, numeric keys, and status indicators, keypads provide real-time system information, event alerts, and easy navigation through settings.
Expanders increase the system’s capacity by adding additional zones, inputs, or outputs, enabling the integration of more sensors, detectors, and peripherals to cover larger or more complex areas without the need for multiple control panels.
Power supply units (PSUs) ensure stable and uninterrupted electrical power to the alarm system, supporting both normal operation and backup power charging for batteries during mains failure. High-quality PSUs protect the system from voltage fluctuations, guaranteeing continuous security monitoring.
Together, these components offer scalable, user-friendly, and reliable control for wired intrusion alarm systems in residential, commercial, and industrial applications.
