The latest addressable fire alarm systems are
smaller, faster and smarter.
In the years since addressable fire alarm
systems debuted in the marketplace, their superior advantages have become
well-known — the ability to pinpoint the exact detector, pull station or other
device that is in trouble or alarm, thereby making it easier for end users,
first responders and dealer/installers to get the job done.
However, like the general electronic marketplace, technology is anything but
static, and the latest incarnations of addressables prove that. New developments
in the technology — both within the detector and panel, as well as their
ability to communicate externally — are bringing addressable technology to more
applications than ever before. Additionally, they are making it easier for the
dealer to install and troubleshoot in all sorts of settings.
“Some of the latest trends in addressable fire systems are speed, power,
agility and ease of use,” says Jack McNamara, director, industry affairs, Bosch
Security Systems Inc., Fairport, N.Y. “Speed has increased in polling time and
the confirmation of a valid alarm.
“Power has been added to the addressable systems to ensure proper operation of
synchronized appliances and added system capacity,” McNamara continues. “IP
makes fire systems more agile, with faster communication to the central
station, and more cost-effective through the elimination of phone lines
dedicated for communications. Customers have also demanded products that are
simple to program and offer intuitive operation.”
SPEEDING UP AND BRANCHING OUT

Addressables have changed in all sorts of ways
in recent years. For one, they are
faster. In the past, polling times and alarm verifications were accomplished in
90 seconds. That time has been drastically reduced now.
“The ability to have an alarm in a shorter period of time is a big
development,” says Laurie Eisner, vice president of product management for
Mircom Group, Vaughan, Ontario, Canada. “Alarm requirements over time have gotten shorter
and shorter.
“Right now the requirement is at 10 seconds, with some jurisdictions requiring
as few as three seconds,” she reports. “So both panels and devices have been
changing over time to be faster.”
They also are smaller. “I think the biggest trend we are seeing across the
board is the continued transition to smaller, addressable systems, away from
conventional systems,” says Shawn Laskoski, marketing leader, fire and
communications, for GE Security, Bradenton, Fla.
Eisner points out that addressable systems are being applied to smaller jobs.
“In the past, jobs with just a few zones might be handled by conventional
systems, but now a lot of smaller jobs are addressable,” she says.
Changes in the way addressables are connected plus the increased cost of labor
are two big reasons for this change.
“Addressable products have moved from a single notification appliance protocol
to multiple synchronization protocols covered by a single panel,” McNamara
says.
“Modules make installations easier,” adds Tim Frankenberg, fire products
manager, Potter Electric Signal Co. LLC, St. Louis. “Originally, systems operated on a single contact
module. Now there are multiple input devices.”
This means that labor is less for an addressable system than a conventional
system. “The equipment is more expensive [for addressables], but the labor is a
lot simpler,” Eisner maintains. “Because labor rates keep going up, the
economics mean the customer will go for an addressable system at a lower and
lower number of zones.”
A single-loop addressable system, for example, requires an installer to pull
just one pair of wires for the system, whereas a conventional system requires a
wire to each zone.
“So if you are installing a 10-zone system, you would need 10 separate wires,”
Frankenberg points out. “With addressables, the same number of zones can be
installed with just one set of wires. With the rising prices of copper, that
also helps reduce installation costs.”
Eisner thinks this reduced wiring makes addressable systems better for retrofit
situations. “It is much easier to fish one wire than multiple wires,” she adds.
“The addressable system makes a lot more sense.”
What this means for the customer is that the cost versus benefit equation now
favors the more feature-rich addressables, Laskoski says.
“There is significantly less labor involved in addressable panels,” he asserts.
“And there are significantly more features. When you put in an addressable
system, every single detector is tracked. A conventional system can only tell
you what zone.
“Previously, the cost point had people willing to forego that,” Laskoski
concedes. “But it is really cost-effective now both from an end-user and from
an installer standpoint to put in that addressable panel.”
What is that cost point currently? Frankenberg believes it is from 10 to 12
zones. “If you have that many, it is less expensive to put in a small
addressable system than a conventional system,” Frankenberg declares. “On the
front end, the cost may be a little more for smoke detectors and modules, but
long-term, addressable makes a whole lot more sense as far as troubleshooting
and maintenance.”
INSTALLATION AND MAINTENANCE BENEFITS
Changes to addressable systems have made it
easier than ever to install and maintain them for the customer. The increasing
proliferation of addressables into smaller and smaller applications means these
benefits are available to a wider range of customers.
Besides less wiring, the new modules also are allowing easier expansion of a
system. “In the past, they had to put in a contact module and use a
conventional device,” Frankenberg says. “Now with the addressable device, they
put a single device in, and they are done.”
Another feature many addressable panels have is synchronization to meet
requirements of the Americans With Disabilities Act (ADA). “NACs [notification
appliance circuits] can drive synchronized strobes,” Eisner says. “ADA
buildings require strobes to all flash at the same rate, and many addressable
panels include those protocols.”
Frankenberg adds that more manufacturers are including synchronization
protocols, which makes them easier to install. Maintenance also can be smoother
using addressable technology.
“In general, addressables are easier to troubleshoot,” Eisner maintains. “The
addressable gets you indications of wiring or device faults down to the point,
whereas conventional is just down to the zone.”
Features like a two-line display indicating the source of a signal, such as
‘Kitchen on 4th floor,’ are available in less expensive panels, she points out.
“It was often lengthy and tedious to maintain conventional systems,”
Frankenberg says. “You didn’t necessarily know where a wire ran.”
SMARTER SYSTEMS

One of the features making servicing and
installing smarter is the integration of IP features into addressable systems.
“Something that is getting a lot of attention lately is IP DACTs [digital alarm
communicator transmitters],” Frankenberg says. “It has to do with the
reporting, how the panel communicates with the outside world.
“With the IP DACT, there is less cost for the installer to run phone lines,”
Frankenberg asserts. “For long-term use on the end-user side, monthly charges
are reduced, which makes an easier sale for the installer.”
Laskoski notes that IP is being incorporated in newer panels. “That is becoming
a trend, with smarter panels,” he says. “You might be able to take one device
off the system and it will recognize that particular device. It is that
continued intelligence and smarts that will further the trend to the IP
networking world.”
This has been an expectation at the high end of the market for a while. “There,
IP is well-used,” Laskoski says of the high-end. “But what we are seeing is
similar addressables replacing conventionals at the lower end. If we were to
have this discussion two or three years from now, it would be all about smaller
addressable networks in the marketplace.”
IP systems make installation and maintenance even more seamless. “On the
installation side, it allows programming remotely, which means much faster
uploading on the job site,” Laskoski says. “On the servicing side, it means the
ability to get more information faster from the panel. If you can get a lot of
information remotely, you can arrive on-site with the correct part in hand.
There is a much greater ability to do diagnostics.”
Another advantage to these communications options is they allow more constant
and reliable contact with central monitoring stations, Eisner says. “With the
addressable system, since you know the exact point, that information can be
sent to the central monitoring system,” she notes. “Panels in general are going
to be more connected with central monitoring going forward.”
WHAT’S NEXT?
Smaller and smaller applications will become the
norm, and the increasing march of Internet-based features can only benefit the
fire industry.
“Our view is that the current bunch of conventional panels being launched will
probably be the last round of new conventional panels to ever hit the
marketplace,” Laskoski maintains. “There will be this continued trend towards
addressable panels in smaller and smaller applications. And they will continue
to get smarter, especially on the installation side.
“I think anyone that is a major player will have entry level addressables,” he
continues. “You will see less and less conventional systems. And I wouldn’t be
surprised if you don’t start to see smaller and smaller networked systems. That
is the next trend in addressables.”
Frankenberg thinks the Internet is the next big thing. “We are just beginning
to broach the idea of the Internet interfacing with addressables,” Frankenberg
declares. “The fire alarm industry is slow to change, but as more manufacturers
start to break that ice, we will see an increasing ability to look at these
systems online and track what is going on that way. It is just getting better
and better.”
