They are dangerous because while they are going to a false call, their can be a real serious call and insted of going to the real call they go to the person who called first. So it risks other peoples lives.
How do you reset a honeywell fire alarm?

Is it illegal for a factory to operate without a fire alarm?
In the United States not all places of employment are required to have alarms...
When required, employers must develop emergency action plans that:
- Describe the routes for workers to use and procedures to follow.
- Account for all evacuated employees.
- Remain available for employee review.
- Include procedures for evacuating disabled employees.
- Address evacuation of employees who stay behind to shut down critical plant equipment.
- Include preferred means of alerting employees to a fire emergency.
- Provide for an employee alarm system throughout the workplace.
- Require an alarm system that includes voice communication or sound signals such as bells, whistles, or horns.
- Make the evacuation signal known to employees.
- Ensure emergency training.
- Require employer review of the plan with new employees and with all employees whenever the plan is changed.
So if the business permit requires a building permit and fire inspection, it would likely be illegal to operate without an alarm except for short periods of maintenance where an alternate fire protection plan is in operation. It would also be extremely stupid and irresponsible to do so.
If your place of employment has alarms installed which do not work, it would be reasonable to report this to OSHA as a suspected violation.

What does UL Fire Alarm System mean?
A UL fire alarm system is a fire system that has been installed to Underwriters Laboratories specifications and is certified by that same group. The system is inspected by a UL certified inspector on a regular basis and the system must at all times adhere to the UL standard. Any changes or modifications to the system must be UL approved.
All of the alarm equipment must be UL certified as well. If the fire system is monitored by a Central Station, the Central Station must also meet the same stringent requirements in order to monitor the signals. The Central Station is also inspected by a UL inspector on a regular basis.
Where will you most likely find fire alarm located?
where will you most likely find fire alarm located
There should be no effect upon the output of any fire alarm due to the number of sensors that are triggered. A fire alarm is a fire alarm, whether it's one sensor or ten.
In theory, a monitored system with more than one or two sensors triggered could escalate the response. When the dispatcher tells people, "Smoke alarm activation", it might get a different response than, "Multiple detectors, more coming each minute...", which could indicate a fast-moving fire.
What is UUFX certification for fire alarm systems?

How high should you install a co alarm?
Most CO alarms are designed to be placed the same way as smoke alarms: within about a foot of the ceiling on a vertical wall or directly on the ceiling at least a foot from the wall. CO is slightly buoyant in air, so it mixes with a tendency to rise and accumulate in a ceiling layer.
In general, any device powered by the fire alarm panel must be listed as compatible with it. There are probably few, if any gas shutoff valves so listed, so probably not.
The normal arrangement for this function is to use auxiliary contacts, either on the panel itself or an intelligent control module to switch an external power supply. This connection should be wired "fail safe" meaning the valve would close if the external power failed.
If you asked this question, you are probably not qualified to design fire alarm systems. This is a life safety system! Get a qualified engineer or NICET IV designer to make sure you have it right. There are numerous codes, standards, and local amendments that must be followed, as well as the manufacturer's guidelines.
Do sulfur candles emit enough heat to set off a home smoke detector or fire alarm?
Home smoke detectors generally respond to smoke, or products of combustion more readily than heat. Unless the candle was placed directly under the detector, it is unlikely to produce enough heat to trip a heat element. It is very possible though, that it could give off enough combustion products to set off the smoke detector.
Which companies sell personal safety alarms?

What are the disadvantages of fire alarm?

What is meant by conventional fire alarm?
A fire alarm that is not addressable. Addressable systems are a lot more complex. They are computerised with the panel with an LCD screen with specialised prgrammed devices to work with that panel/system. An addressable system acts like a computer network, with the panel being the server and the devices (call points, detectors, sounders etc) being the computers.
Conventional systems are far more basic and used in smaller, less complex applications. They usually don't have an LCD screen and the panel will work with mnay devices. It works more on a basic electrical circuit basis rather than computerised products.
