What FCM 1?
The FCM-1 Intelligent Addressable Control Module is used to switch an external power supply, which can be a DC power supply or an audio amplifier (up to 80VRMS), to visual or audible warning devices. The FCM-1 supervises the wiring to the connected loads and reports their status to the panel.
What is the difference between relay module and control module?
What is the difference between a relay module and a control module? Relay modules are typically on off devices while control modules are typically variable output. Relay modules can be control modules if a switching control scheme.
What is a control module in fire alarm system?
The fire alarm control unit is responsible for sending a signal to the smoke control panel to initiate smoke removal when specific smoke detectors, pull stations, and waterflow alarms within the protected space are actuated.
What is control module?
A control module is a collection of sensors, actuators and basic control logic that acts as either a regulating device, a state-oriented device or a combination that is operated as a single device. Examples of control modules are PID controllers and block valve controllers (refer Figure 4.8).
Why do we use relay module?
The relay module is an electrically operated switch that can be turned on or off deciding to let current flow through or not. They are designed to be controlled with low voltages like 3.3V like the ESP32, ESP8266, etc, or 5V like your Arduino.
How do relay modules work?
Relay Modules
A power relay module is an electrical switch that is operated by an electromagnet. The electromagnet is activated by a separate low-power signal from a micro controller. When activated, the electromagnet pulls to either open or close an electrical circuit.
What are the 4 basic types of alarm panels?
There are four basic types of panels: coded panels, conventional panels, addressable panels, and multiplex systems.
What are the 4 basic parts of fire alarm?
The Five Basic Parts of a Fire Alarm System
- Fire alarm control panel.
- Initiating devices.
- Notification devices.
- Primary power supply.
- Backup power supply.
What ECU means?
electronic control unit
April 16, 2020. An electronic control unit (ECU) is a small device in a vehicle’s body that is responsible for controlling a specific function.
What is the difference between ECU and ECM?
What is an ECM or ECU? ECM stands for engine control module, while ECU stands for engine control unit. While these two have a different name, the modules are essentially the same thing. These electronic modules control multiple systems of the vehicle, including the ABS, airbags, cruise control and air conditioning.
What is relay principle?
Relay works on the principle of electromagnetic induction. When the electromagnet is applied with some current, it induces a magnetic field around it.
How do I use 2 relay modules?
Two Channel Relay Module Pinout
- VCC pin supplies power to the built-in optocoupler and optionally to the electromagnet of the relay (if you keep the jumper in place)
- GND is the common Ground connection.
- IN1 & IN2 pins are used to control the relay.
- JD-VCC supplies power to the electromagnet of the relay.
What is the difference between relay and relay module?
Essentially, they work as switches. Your average relay module comprises two internal metal contacts. Usually, these contacts do not connect or touch each other. However, relays include an internal switch connecting these contacts to complete an electrical circuit that allows current flow.
What are the 7 types of alarm system?
An alarm system just notifies you when it’s too late.
- Motion Sensor Alarms.
- Fire Alarm System.
- Water Alarm.
- Door Sensor Alarms.
- Heat Alarm.
- Infrared sensors.
- Contact Sensors Guide.
- Intrusion Alarm.
What are the 3 main types of alarms?
What types of alarms should you have at home?
- Smoke alarms. A smoke alarm, or smoke detector, is a device that makes a loud noise when it senses smoke in the air.
- Burglar Alarms.
- Carbon monoxide alarm.
- Personal Alarms.
What are 3 main components of a fire alarm system?
The system inputs consist of fire detection devices and system monitoring devices that activate the control panel and the outputs are responsible for occupant notification and control functions associated with life safety.
What are the 3 main parts of an alarm system?
The most important are:
– detectors; – the control panel; – the keyboard.
What causes ECU failure?
One of the main causes is a short circuit in the wiring or in components, which can cause them to burn out. This short circuit is often caused by external influences, such as the wrong start of the car.

What are the 4 parts of a relay?
An electromechanical relay is basically designed using few mechanical parts like Electromagnet, a movable armature, contacts, yoke, and a spring/frame/stand, these parts are showing in the internal pictures of Relay below.
What are the 5 applications of relay?
Micro Photoelectric Sensors.
What is the difference between 1 channel and 2-channel relay?
A 1-channel relay board can switch one load, a 2-channel relay board can switch two loads independently.
What are channels in relays?
In information theory, a relay channel is a probability model of the communication between a sender and a receiver aided by one or more intermediate relay nodes.
How many types of relay modules are there?
Depending on the operating principle and structural features, relays are categorized into different types mainly: Electromechanical Relay. Solid State Relay. Reed Relay.
