Amsecos Piezo-A-Lert Model ESZ-25 is specially designed as advanced electronic audible signaling device that is extremely quiet on stand-by, emitting less extraneous noises because it has no oscillator coils in their electronic circuits. The ESZ-25 produces an extremely loud sound output.

Most piezo type buzzers are energized piezo electric transducers operating at a resonance in a solid state oscillator, but the ESZ-25 has a completely different design. Both units operate on as little as 5V DC to as much as 28V DC and are rated at 20mA operating current at 24V DC. The ESZ-25 is quiet on standby and because of this it is highly recommended for use on microcomputer electronic equipment. Since microelectronic computer equipment is very sensitive to extraneous noises, the ESZ Series Piezo Alarms are excellent choices for security alarm requirements.

The ESZ-25 has a multi-functional mounting method. By simply unscrewing the face nut it can be inserted into any standard knockout hole. By screwing the nut back in place, there will be a solid mounting. On the base, located on either side, are two loops. Inserting screws in these loops will allow the device to be surface mounted. The two loops may be cut off if not required.

The Piezo-A-Lert signal operates in free air only. It is not compatible with under water applications. The recommended operating temperature range is -4F to 140F (-20C to 60C).
