CPE-121

CPE-121 is a type of switch controller with built-in relays that can be used as an alarm panel, buzzer, and siren. This versatile device provides the user with precise control of a variety of functions associated with its applications. The CPE-121 has a number of usage scenarios, from office alarm panels to loud-hailer systems, that make it a highly versatile device. It can be used for building or vehicle applications, as well as industrial applications.

Application Field

CPE-121 is often used in fire alarm systems to detect smoke and carbon monoxide, and also in burglar alarm systems. It can also be used as a buzzer, timer, and siren in public address systems or remote control operations. In addition, it is commonly used in industrial applications such as factory automation warning systems and door control.

Working Principle

The CPE-121 is designed with two relays that can be controlled independently. It is equipped with two normally open contacts and two normally closed contacts. This allows the user to configure a variety of warning horns and other auxiliary equipment depending on the application.

The CPE-121 is powered by a 9V battery or AC transformer. When the alarm is activated, the normally closed contacts will open and the normally open contacts will close, sending a signal to the connected devices. This signal can be configured to sound a loud warning horn, as well as trigger other auxiliary devices.

The CPE-121 also has a timer built in to allow for timed activation of alarms and auxiliary equipment. This can be used to set up an automatic warning system that will activate or deactivate at a designated time. This timer also allows for the control of alarm sequences and multiple levels of warnings.

The CPE-121 is a versatile and reliable device that can be used for a number of applications. Thanks to its programmable contacts and timer, it is an incredibly flexible device that is easy to install and configure.
