Fire alarm panel is the brain of fire alarm systems. Basically, it receives data from input devices, evaluates those data and then triggers output devices.
What is input device in fire alarm system?
Input modules monitor devices responsible for alarm inputs and confirm signals or technical states etc. The input lines are monitored for open and short circuits. Addressable modules can be independently configured via a fire control panel for status or alarm messages.
What is alarm output device?
Alarm Output Devices
Bells, sounders, horns and speakers are part of audio notification – strobes, flashing lights and beacons are part of visual notification. Speakers are generally used to transmit a pre-recorded voice message to alert the occupants.

Is a siren input or output?
24 hour Input Devices: These are special types of sensors that activate the alarm whether it is turned on or off (24 hours a day). These include fire/smoke sensors and water leak sensors. Output Devices: Example output devices include horns/sirens and strobe lights.
What is a fire alarm output?
Output module is another fundamental output device in fire alarm systems. They are used for integration of fire alarm systems and other electrical or mechanical systems in the building. Output modules control other systems in case of fire so that fire scenarios can be implemented.
What is a fire alarm output module?
The Addressable Input/Output Module is a fully monitored device which permits the interfacing of third party equipment with the Fire Alarm Control panel using normally open dry contact connections while also providing a changeover output relay to control ancillary equipment.
Which fire alarm component sends a signal to the Fire Alarm Control panel?
Unit (FACU) — The main fire alarm system component that monitors equipment and circuits, receives input signals from initiating devices, activates notification appliances, and transmits signals off-site. Formerly called the fire alarm control panel (FACP).
What is an input module?
An Input Module is where the main logic of an event system can be configured and customized. … The built in Input Modules are designed to support common game configurations such as touch input, controller input, keyboard input, and mouse input.
Is a motion sensor an input or output device?
A motion sensing input device of a computer system includes a motion sensor and a receiver. … The motion signals are wirelessly transmitted to the receiver connected with the computer system.
How do you determine fire alarm zone?
It should show the building exits, stairs, corridors, lifts etc. The fire alarm zone plan should be located next to the fire alarm panel, which can immediately identify where any potential fire situation may have occurred.
What is a Category L3 fire alarm system?
The purpose of an L3 fire alarm system is to provide warning to occupants beyond the room in which the fire starts, so that they use escape routes, such as corridors and staircases, before they are smoke-filled. Fire alarm detectors should be installed in all escape routes and all rooms that open onto an escape route.
What are the examples of an input and output in a control system?
A simple weather station can be looked upon as the following;
- INPUT – the sensors (temperature, rain fall, humidity etc..)
- PROCESS – the computer that analyses the incoming data.
- OUTPUT – the final printout of temperature etc…. The system above is a closed system because it has feedback.
What are the output devices at a supermarket?
Touchscreen – fingers control a device through selecting icons. Screen also outputs images. Used for tablets, smartphones and some supermarket self-scan checkouts.
Output devices include:
What is input in control system?
In control system, input is any response or action desired to be produced in a system. The reference input is called setpoint. On the other hand, output is the actual response of the system.
