Automatic Timer relay Using Alarm:
This diagram shows how to make Automatic Timer relay Using an Alarm. In this circuit, we use a terminal block, an 8-pin timer relay, an SP MCB( Single Phase Miniature Circuit Breaker), an alarm siren, and a relay. First, we need to connect the SP MCB, then connect the timer and relay with phase connection, then connect the alarm siren. Now this circuit is ready for use. If you want to know more about this circuit please check our youtube video below the post.

Components used to make the timer alarm:
01. SP MCB

| Fig 2: SP MCB |
MCB SP means single pole it protects only one phase switching. MCB (Miniature Circuit Breaker) Curswitch 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. (MCB) For any Distribution Board, the Protection System Must be Used in The Incomer. Phase and Neutral Single Phase Supply to break. 120-volt circuits, 15-20 amp single pole breaker is typically used.
02. Timer

Timer is a specialized type of clock used for measuring specific time intervals.An electromechanical cam timer uses a small synchronous AC motor turning a cam against a comb of switch contacts. This type of timer often has a friction clutch between the gear train and the cam, the cam can be turned to reset the time.A simple example of the first type is an hourglass. Working method timers have two main groups: hardware and software timers.Most timers give an indication that the time interval that had been set has expired.
03. 8-pin relay

This relay is known as 8 pin relay because it has 8 terminals. When coil power is supplied. A magnetic induction is created due to which the connected sheet of the Com part moves towards the NO part changing to NO-NC. The former NC region loses conductivity and becomes NO. Thus, as long as power is supplied to the coil, the NO and NC positions will remain in the alternating state, and when the power is removed from the coil, it will return to its original position. This is basically how a relay switch works.
04. Alarm Siren

An Alarm Siren is a Loud Noise-Making Device. Civil Defense Alarm Sirens are Mounted in Fixed Locations and Used to Warn of Natural Disasters or Attacks. Alarm Sirens are Used 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

| Fig 6: Terminal Block |
A Terminal Block Consists of Modular Housing With An Insulated Body That Secures Two Or More Wires Together. Terminal Blocks—Also Referred to as terminal Connectors, Connection Terminals, or Screw Terminals—are Used in a Wide Array of Applications Where Electrical Systems Need to be Safely Connected. Electrical Terminals are a Class of Electrical Connectors That are Used to Transfer Electrical Current From a Power or Grounding Source to use. Terminals "Terminate" by Crimping or Soldering to Wire or Cable.
