Para Fire Systems, which works out of Magnolia, Texas, describes its commercial fire alarm business in three parts: installing fire alarms, repairing them, and ERRC testing. Each one solves a different problem for a building owner, and each tends to arrive at a different point in a building's life. This post walks through the three services as the company describes them on its website, and what each one means in practice for someone responsible for a commercial property in Houston or elsewhere in Texas.
A new installation usually comes with new construction, a major renovation, a change in how a building is used, or a system that has reached the end of its useful life. In each case the system is designed for the building in front of you: the occupancy, the floor plan, the people inside and the code edition the local jurisdiction has adopted.
Para Fire Systems' services page frames the purpose of an installed system around the hours when no one is watching. Alerting the people on site matters, but the company notes that in most buildings the greatest risk of loss occurs when the facility is unoccupied. When a fire goes unnoticed and the fire department is not notified, the page says, the fire can spread and do damage that cannot be undone, especially where there is no sprinkler system. Early detection, and getting the alarm to someone who can act on it, is the point of the whole exercise.
For an owner, an installation project typically involves plans for the system, review and permitting with the local authority having jurisdiction, or AHJ, the installation itself, and an acceptance test before the system is put in service. The exact steps and paperwork depend on the city or county.
Repair is the service most owners need without warning. A panel shows a trouble condition, a device fails during an inspection, or a new owner finds that the system they bought does not behave the way it should.
The company's services page is direct about one cause: not every fire alarm is installed correctly. It says Para Fire Systems corrects and repairs fire systems, including ones that were installed wrongly in the first place, and it notes that a flawed installation can make it impossible to pass an inspection. The page adds that the company never wants to see a customer go without proper fire protection.
Repair work on an existing system often begins with understanding what is there. That means identifying the panel and devices, reviewing past inspection reports if they exist, and tracing a fault back to its cause rather than clearing a symptom.
The third service is the least familiar to many owners. Emergency responder radio coverage, or ERRC, is about whether firefighters and police can count on their portable radios once they are inside a building. Radio signals that work fine on the street can fade in basements, parking levels, stairwells, elevators and behind thick concrete or masonry.
The work comes in two linked pieces. The first is the testing the listing names: measuring how well public safety radio signals reach the inside of a building, and how well a radio inside can reach the network outside. The second, where coverage falls short, is the installation work described on the company's services page: a bi-directional amplifier system, known as a BDA, which bridges the outdoor public safety radio network and the inside of the building so that signals travel in both directions.
The company lists the kinds of spaces it builds BDA systems for: high-rise buildings and large complexes, basements and subterranean levels, reinforced structures, and stairwells and elevators. It also lists support for the VHF and UHF bands, the 700 MHz and 800 MHz bands and FirstNet-ready coverage, along with fire-rated enclosures and battery backup intended to keep the system running through a power outage.
The page also ties radio coverage to the certificate of occupancy, and in jurisdictions that require in-building coverage it can be a condition of occupying a new building. Whether that applies to a particular building depends on the code edition the jurisdiction has adopted and how the local fire marshal applies it.
On paper these are three separate services. In a real building they overlap. A new building may need a fire alarm installation and a radio coverage assessment on the same schedule. An older building may need repairs to bring its fire alarm into order, and then an ERRC assessment when a renovation raises the question. Having one company that handles both can reduce the number of contractors an owner has to coordinate.
Para Fire Systems' About page describes its offer as easy-to-use, one-stop, total fire protection services. The same page mentions record keeping: reports for insurers, plus a customer's inspection history and due dates held together.
Before contacting any fire alarm company, it helps to collect a few things: the building's address and rough size, the make of the existing panel if there is one, recent inspection reports, any deficiency notice from the fire marshal, and the deadline you are working to. With those in hand, a conversation with Para Fire Systems, or any contractor, moves faster and ends with a clearer scope of work.
