PK-27N35PSQ

Alarms, Buzzers, and Sirens are designed to alert and inform people of a particular event or situation. The PK-27N35PSQ is an example of a siren, typically used in industries for warning and signaling applications. It is designed to provide reliable operation, excellent protection against dust and dirt, and long-term mechanical strength.The PK-27N35PSQ is an electronic siren with an oscillating sound. It produces sound with an amplitude of 27 dB (A) at a distance of 1 meter from the device. The siren has a maximum sound pressure level of 95 dB (A) for a sustained sound lasting for 2 minutes and 112 dB (A) for a peak sound lasting for 6 seconds. The siren has an integrated piezo driver producing a uniform sound output with a frequency range of 2625-3200 Hz. The device has a built-in thermistor, allowing it to shut down in case of an over temperature situation.The siren has a wide range of application field and is used in fire alarm systems, general alarm systems, security alarm systems, process signals and in gas leak detection systems. The siren can also be used in other safety related applications such as in medical alarm systems, noise control systems, and in machine status change notification systems.The working principle of the PK-27N35PSQ is based on an oscillating circuit. The oscillator is an electronic circuit, which is powered by a DC voltage. It produces a repetitive waveform when the capacitors and resistors are connected in a specific circuit configuration. The waveform is then amplified and sent to the piezo driver, which produces the audible sound waves. The siren also includes a thermistor, which shuts down the siren in case of an over temperature situation.The siren can be installed in both indoor and outdoor applications. It is designed to withstand tough environmental conditions such as wide temperature range, corrosion, vibration, moisture, dust, and dirt. The siren is capable of working in a voltage range of 24-45 VDC and is IP65 rated, making it suitable for use in wet and dirty areas.The PK-27N35PSQ is a reliable and high-performance siren, suitable for various industries and applications. It is designed to provide a long-term and reliable operation in various challenging environments and is suitable for both indoor and outdoor applications. The siren also features a wide frequency range, consistent sound output, and a built-in thermistor for protection against over temperature situations. All of these features make it an ideal choice for ccomplicated safety and signaling applications, such as in the fire, security, and medical alarm industry.
