Automatic Timer Relay Using Alarm:

This diagram shows how to make Automatic Timer relay Using an Alarm. In this circuit, we use an alarm siren, a timer, an SP MCB ( Single Pole Miniature Circuit Breaker ), and a relay. First, we need to input the phase line into the MCB, then input the connection to the timer, relay, and alarm siren as in our diagram. Then we need to input a neutral connection to all components. Now this circuit is ready for use. If you want to know more details about this circuit please check our youtube video below the post.

Components used to make the Automatic Timer relay Using Alarm:

01. SP MCB:

In single-pole MCB, Switching & Protection is Affected in only one Phase. Single phase supply to break the phase only. A single Pole breaker is Typically used with 120-volt Circuits, 15-20 amps. They are constructed with one Hot Wire and one Neutral wire. An SP switch is the most basic General-Purpose switch that you use to Control a light or another device from one location. These Switches have two Brass-Colored screw Terminals Connected to the hot Power source wires. Pole refers to the number of Circuits Controlled by the Switch SP Switches Control only one Electrical Circuit.

02. Timer:

A timer is a type of time-switching device that controls and controls electrical circuits and electrical and electronic devices through time setting (on/off). The timer is basically 8-pin. Like other controlling devices the timer has a coil and when this coil is magnetized, the timer works on/off. The timer has two common ends and each common end has normally close and normally open options. When the timer is set by time, the timer trips at the end of that time and turns the common’s normally closed (on) to open (off) and normally open (off) to close (on). This is how the timer works.

03. 8-Pin Relay:

The most popular relay for automation work is the 8 Pin Relay. 8 pin relay has DC or AC coil as the main part. which is connected to two pins. There are two common parts. Underneath a Common part are an NO and an NC part. No part is normally open with a common part and the NC part is normally closed. The timer base used for automation is the same as the 8-relay base. That is, switching can be done using the timer base. This is basically how a relay switch works.

04. Alarm Siren:

A Siren is a loud noise-Making device. Civil Defense Sirens are Mounted in Fixed Locations and Used to Warn of Natural Disasters or Attacks. Sirens are Wsed on Emergency service Vehicles Such as ambulances, Police Cars, And fire Engines. There are two General types: Mechanical and Electronic. A civil Defense siren, also known as an air-raid siren or Tornado Siren, is a Siren Used to Provide an Emergency Population Warning to the General Population of Approaching Danger.

05. Terminal Block:

Terminal Clocks are Connectors That Terminate a Single wire and Connect it to a circuit or other system. Terminal Blocks come in a range of shapes, Sizes, and ratings, but Always Terminate a single Wire and are Never multi-pole. Terminal Blocks are used to Secure and/or Terminate Wires and, in Their Simplest form, Consist of Several Individual Terminals Arranged in a long strip. Terminals are Useful for Connecting the Wiring to the Ground or, in the Case of Electrical power, for Connecting Electrical Switches and Outlets to the Mains.
