CPE-270

Alarms, Buzzers, And Sirens Overview

The CPE-270 is an internally driven piezoelectric buzzer designed for panel mounting with wire leads. It operates within a voltage range of 3 to 28 VDC, with a rated voltage of 12 VDC and a supply current of 5 mA. The device produces a continuous tone at a frequency of 3.5 kHz with a sound pressure level of 86 dB measured at 12 V and 30 cm distance. Its physical dimensions include a diameter of 33.70 mm (1.327 inches) and a maximum seated height of 15.00 mm (0.591 inches). The unit features a flange for secure installation and supports an operating temperature range from -30°C to 85°C.
