To control and power are fire alarm system. You can manually sound, silence, disable alarms. You can dis-connect circuits when doing work. They usually have battery back up so that the system remains powered up when there is a power failure. (They are mains powered).

They can also be connected to the local fire service, so when there is an alarm condition, then it automaticaly calls the fire service to quickly arrive in the case of a fire.

It may also be connected to realy devices to turn off big machinery. When there is a fire alarm, all dangerous machinery that could add to the cause of the fire will be switched off for safety reasons.

Most fires in a control panel are caused by a short circuit in the control wiring. This can be caused by improper fusing of control devices. Some control panels are installed in a dirty combustible environment which leads to a contamination build up due to the panel door not fitting tightly. I have found 6" of wood chips in the bottom of the panels due to poor maintenance practices. Control Transformers are another location a fire can start in a control panel.

How safe is a 1969 zinsco electrical panel?

They are not at all safe and are junk that needs to be recycled and never installed even in a barn let alone a home. Zinsco company went out of business partly because it was discovered that their breakers did not trip when they were supposed to. For this reason they are nothing but a fire hazard and are not to be trusted to protect the wiring in your home or your family from a fire. Do not use any Zinsco or FPE service panel. Destroy this panel so that no one can ever use it.


Can the color purple conductors be used for a three phase 277 volt panel?

Purple or violet coloured wires are usually reserved for control panel wiring and are not usually found in a wire sizes over #16 AWG.


Why you use ELR?

An ELR is terminology used in fire alarm systems. It stands for End of Line Resistor. It is used as a load on individual fire alarm circuits. This load draws a small current that is monitored by the alarm panel. What the panel is monitoring for is open circuits in break glass and bell circuits. If the current is non existent then it means that one of the fire circuits is opened, out of service and non operational. In the alarm panel a relay is de-energized and a trouble alarm is activated to bring attention to the problem. Once the problem is repaired the current again flows through the ELR and the trouble relay resets.

How a mimic panel works in fire alarm system?

Mimic panel in fire alarm system 'mimics' or mirrors the signal of the Main Fire Control Panel.


What is the use of repeater panel in fire alarm control panel?

Repeater panels, also known as Annunciator panels are used to provide a visual display of the main panel. They can additionally provide limited control functions, such as acknowledge, silence, and reseting the main fire alarm panel.


Why are use plate Repeater in the fire alarm system and Where to install?

Plate Repeater is used in the fire alarm system so that it shows the same information that the main control panel does. The repeater panel looks a lot like the main control panel and can be placed up to 30 meters from the main control panel.


Fire detection remote control panel?

An additional panel which is connected to the excisting main control panel, displaying all the information that the main panel displays in another location. For example, in an offcie building, you may have the main control panel at the main entrance/exit while you have the remote panel in a security/fire office somewhere else in the building so that the cause of the fire alarm can be easily identified without having to go across one building.

What is the minium size branch circuit for a fire alarm system?

Are you referring to the circuit supplying power to the control panel or the initiation/notification branch circuits controlled by the fire alarm system? The ampacity of the fire alarm control panel would determine the circuit size of the branch circuit supplying power to the control panel and the terminal on the control panel and fire alarm device would detrmine the size of conductor that it will accept. Most fire alarm control panels would require a minimum 15 amp circuit. The minimum conductor size allowed per the NEC would be 14 AWG. 22 AWG. is the smallest conductor that most control panels and device terminals will accept. These are considered Power Limited circuits.


How do you turn off a fire sprinkler tamper alarm?

First you locate the source of the alarm, undo the condition (e.g., valve closed, inadequate pressure, etc), then reset the alarm condition on the sprinkler control panel and reset the alarm on the fire alarm control panel (assuming they're connected, as required by many fire codes).


What is the difference between 'Class A' fire alarm vs 'Class B' fire alarm wiring?

In class A wiring, 2 wires start from alarm control panel terminal, run through fire sensors / detectors and the same 2 wires run back into the alarm control panel and get connected as 2 more wires thus there would be 4 wires at the panel totally. This would help the control panel monitor all the sensors / detectors even if a loop wire breaks in the middle. In Class B wiring, the control panel is just connected to 2 wires. These 2 wires run through fire sensors / detectors and terminate at end of line resistor. Thus if any wire breaks in between the sensors that are connected to control panel end of wire would only be monitored. The broken wire side of sensors won't be monitored

What is the difference between a repeater panel and a mimic panel in a fire alarm system?

A repeater panel looks nearly or identical to the main panel. You can control the functions of the panel that you can do on the main panel. A mimic panel just simply 'mimics' what happens on the fire alarm system. You can't do any functions like enable/disable or sound/silence alarms etc. It has an in built piezo buzzer when a fire alarm is activated, the mimic panel displays this status and tells you the zone/zone description. It may also tell you any faults that have occured. You can silence the buzzer on this mimic panel.
