Potter ESZ-25S

Description

Amseco’s Piezo-A-Lert Model ESZ-25 and ESZ-26 are specially designed as advanced electronic audible signaling devices that are extremely quiet on stand-by, emitting less extraneous noises because they have no oscillator coils in their electronic circuits. Both ESZ-25 and ESZ-26 produce an extremely loud sound output. Most piezo type buzzers are energized piezo electric transducers operating at a resonance in a solid state oscillator, but ESZ-25 and ESZ-26 have 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 and ESZ-26 are quiet on standby and because of this they are 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 and ESZ-26 have a multi-functional mounting method. By simply unscrewing the face nut it can be inserted into any standard ¾” 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.
