Alarms, buzzers, and sirens are devices used for alarm and warning applications. PK-27A25WQ is such an alarm. It is mainly used in home and commercial buildings for applications requiring an immediate response.
The PK-27A25WQ is an enhanced alarm system that provides higher sound levels and better sound quality than traditional alarms. It features a self-contained power supply unit with a 10-amp circuit to provide enough power to maintain a loud and consistent sound output. The PK-27A25WQ also has a reliable and accurate time control system with a 24-hour programmable clock that allows the alarm to sound at pre-set times.
PK-27A25WQ is a 120V AC line powered enclosed alarm featuring dual alarms, tamper-proof switching, and auto reset. It is an ideal solution for applications that require audible security alerts or notifications. It is designed to be used in two modes—Timed On and Off, or Chime. The Timed On and Off mode enables the alarm to be programmed to sound continuously for a specific length of time. The Chime mode allows the alarm to sound at pre-set times, such as at night or when certain events occur.
The PK-27A25WQ operates using an on-board microcontroller and a digital signal processor (DSP). The processor turns on the device based on the status of the input signals, and it manages the sound output by adjusting the output power over a wide range. The microcontroller monitors the device’s status, and it sends a signal to the power circuit when the alarm is activated. This ensures that the alarm operates independent of the power supply and that it will sound even without external power.
In addition, the PK-27A25WQ features an enhanced audio output circuit that produces a loud and clear sound signal at volumes up to 95 dB. This sound signal can be adjusted to different volumes, allowing it to be customized to the user’s needs. The PK-27A25WQ also has a durable, tamper-proof housing for added protection.
The PK-27A25WQ is an effective and reliable alarm system that is ideal for applications requiring an immediate response. It offers a self-powered system with a 24-hour programmable clock and adjustable sound levels. In addition, it has a strong and durable housing and meets the requirements of UL and cUL certification standards.
