What Is A Temporal Fire Alarm System Design?

 

Temporal Fire Alarm System design is a typical design of a fire alarm that uses a unique three pulsed sound to alert the occupants of a building. It is programmed differently from conventional fire alarm systems that use a constant sound.

It was found that the conventional systems are not effective with their sound levels. They were notorious of inaudibility, disruptions and tampered voice signals hence Chicago building codes adopted the T3.

On 1 July 1996, the American National Standard (ANSI) has adopted the Temporal Three Alarm Signal as the new fire alarm system design in all buildings built thereafter. This is the design followed by many countries around the world due to its convenient pulsed patterns of notifying occupants of a building about an emergency.

Buildings that were using conventional fire alarm systems are urged to convert to the modern Temporal System Design. There are many benefits of using T3 as the Audible Emergency Evacuation Signal. Temporal Signal is in compliance with the ANSI S3.41 and ISO 8201. So, rest assured that you are installing an international system design in your building to safeguard your life.

Temporal Fire Alarm System is in compliance with NFPA 72 building code that enforces the application location, installation, maintenance, monitoring, testing, and inspection of fire alarm systems in the Pakistan. Thus, all new buildings in Pakistan should take cognizance of this new fire alarm system.

If your new building is designed by Pakistani Engineers , we will ensure that it meets all fire safety regulations as stipulated by the NFPA 72 code.

 

How Does The Temporal Fire Alarm System Design Work?

 

 

The Temporal Fire Alarm System differs from conventional fire alarm systems with the way the sound signal is dispensed to building occupants. For instance, a conventional system would produce a constant sound that may be distorted or inaudible to some hearing-impaired building occupants. This, in turn, has caused inconveniences by putting others at risk of the fire emergency.

Temporal Fire Alarm design is an effective way to notify occupants of a building to evacuate the building. How is this done? Well, the design works with a pulsed audio signal that lasts for a minimum of 180 seconds. Ideally, there is a pattern of how the sound is produced.

The basic pattern is a three pulse which lasts for 0.5 +/- 0.05 seconds and then followed by 1.5 seconds of silence. This sequence repeats for over 180 seconds. Such a pattern has been proven to be effective in alerting occupants and emergency responders about an imminent fire occurrence in the building.

However, NFPA 72 emphasizes the need to isolate this alarm design from other systems to avoid confusions. Also, building occupants should be trained about this pattern so that they do not confuse it with other similar patterns that might signal other occurrences. Pakistan Engineers technicians can undertake the training to educate your tenants about the reaction to Temporal Fire Alarm signals.

Installation Of Temporal Fire Alarm System Design

alarm Installation

Not anyone is allowed to install fire alarm systems due to the nature of risk associated with their purpose. Fire safety regulations reinforce the need to have a certified fire technician to install fire alarms in all buildings. At Pakistan , we have a wealth of experience in fire protection engineering services. Our services extend to all areas across the Pakistan and beyond the borders.

Our design, installation, and location are guided by NFPA 72 requirements.

Find hereunder special requirements stipulated by NFPA 72 and the International Building Code:

  • All fire alarm system designs shall be addressable systems. No more inconvenient conventional system designs
  • Fire alarm systems installed in large buildings that house 500 or more occupants shall be voice or alarm communication system
  • Both automatic and manual responses shall be provided to building occupants to alert them about a possible danger
  • Fire alarm systems should be isolated from other building systems that might interrupt them. These include building automation, security alerts, energy management, etc. Fire alarm systems shall be independent of other building systems.
  • Fire alarm systems wiring shall be a solid copper installed in conduit. No stranded wiring is allowed.
  • Fire alarm systems shall be protected from electrical surges, over-voltages, brownouts, sags, spikes, and noises by means of a hardwired mini-computer power conditioner. And this conditioner shall be U.L listed and shall have integrated overload protection.
  • Conduit shall be an electrical metallic or a rigid metal tubing with a minimum inside diameter of 3/4 inch.
  • Wiring supervision for the fire alarm systems shall be guided by NFPA 72 requirements.

This is only a handful of requirements stipulated by the NFPA 72. Many of them can be too technical if you are no tech savvy, but New York Engineers are well rounded with all sets of requirements. We design fire alarm systems from scratch, install, and monitor them on your behalf.

Why Hire Technicians To Install Temporal Fire Alarm System Design?

 

Besides being mandatory to have a certified technician to install the Temporal Fire Alarm System Design, it can be overwhelmingly challenging to configure the system if you are not a tech person. The design and the installation are complex and so you need a competent technician to accomplish it for you.

When designing a Temporal Fire Alarm System, our technician takes into account the levels of protection required and enforced by NFPA 72 building code together with other authorities such as insurance agencies. The technician then details specific components and arrangements in line with the preset expectations of fire protection. What you get is an optimally efficient fire alarm system for your building.

Not only is our technician guided by the NFPA 72 but also the ISO 7240-14, which is the international standard for design, installation, service, and commissioning of fire alarm systems. This international standard was enacted in 2013 August by the ISO technical committee.

Still on the design and installation, one has to take into account the parts of the fire alarm system. At the heart of every fire alarm system lies the control panel which serves as the control unit for the entire system. It facilitates communication between the devices, occupants, and the emergency responders.

Also, there must be a power supply: 120 or 240 volts of alternating current from a commercial power utility. In case the primary power gets disrupted, a secondary power supply must be in place to ensure that the Temporal Fire Alarm System always functions uninterrupted. Fire can emerge even when electricity supply is off, and so you need a reliable power supply apart from the primary source supplied by the commercial power utility or branched circuits. 

In addition to the control panel, there are initiating devices that include smoke detectors, heat detectors, pull stations, and other akin devices. They can be manually or automatically activated. These devices act as inputs to the control panel to complete the fire alarm system.

Furthermore, there is a fire alarm notification appliance that alerts the occupants about an impending fire emergency. The appliance uses the energy supplied by the fire alarm system. The methods of alert could vary from incandescent light, flashing light, bell, speaker, electronic horn, or the siren.

You are probably stunned by this comprehensive information about the installation of Temporal Fire Alarm System. To avoid such a shock,  can hand you a competent technician who will make sure that all fire safety requirements are being taken care for. From the design to the installation and monitoring of the system, our technicians are well rounded to help you.

 

What Are The Benefits Of Temporal Fire Alarm System Design?

Audibility of the fire alarm system is vital in a fire emergency. Temporal Fire Alarm Design achieves that by using a three pulse audio to alert occupants of a building. As already described above, it is a three pulse with sounds lasting 0.5 seconds and a silence of 1.5 seconds for a minimum of 180 seconds.

Studies found out that Temporal 3 Fire Alarm Systems are effective for senior citizens and those with hearing problems compared to conventional alarm systems. This has led to the adoption of these systems as standard to replace the conventional fire alarm systems in all buildings.

Moreover, T3 Fire Systems are not limited to fire alerts only but other emergency communications such as weather and chemicals. The systems integrate well with smoke, gas and heat detectors. Pakistan Engineers can configure all these needed settings to make your fire alarm system functional in a blink of an eye.

Technologies For ARCS In Buildings

Radiating Cable Systems

Radiating cable systems broadcast radio frequency (RF) signals via a long, flexible antenna with slots known as a radiating cable. The slots in the cable have led to its nickname, leaky cable!

Radiating cable systems are passive systems that don’t amplify RF signals and tend to lose signal over distance. Their reliability is also affected by interference with RF signals.

Radiating cable systems are used to enhance the capability of emergency two-way radios and they are commonly installed in both new and existing buildings. The cable itself is available in multiple lengths and the antenna system can be installed in stairways, corridors, and mechanical shafts within buildings to ensure there is RF coverage throughout the building or facility.

Distributed Antenna Systems

 

A DAS comprises managed hubs and remote antennas that distribute an RF signal to a portable radio or LMR within a building.

A DAS may use active and/or passive components and it incorporates a base station or repeater that provides the signal. The signal is sent to the main hub that digitizes it and then distributes it to other hubs and radios through a high-bandwidth fiber-optic network. By digitizing signals, the DAS can transport them to any of the remote antennas that are connected, regardless of how far away they are from the base station and main hub within the building.

Like radiating cable systems, a DAS may be used in both new and built structures that need enhancement of their emergency two-way radio capability. Amplification systems and bi-directional amplifies are components of this type of system, so by focusing on base station signals at a specific area, the DAS can deliver more consistent coverage with higher capacity via its remote antennas.

Pakistan Engineers specialize in auxiliary radio communications systems that comply with all the relevant codes and regulations to ensure your safety. If you own a high-rise building in Pakistan and don’t have an ARCS, you should talk to us.
