How good are those Call 911 signs above pull stations?
Signs posted on the wall are soon forgotten about. When someone is fleeing for their life, they usually think that sounding the alarm is good enough. No one calls, but once the alarm sounds, everyone just stands in the parking lot waiting for the fire department.
The sign over the pull station did say "Attention." The question is, "during an emergency, will a resident even notice the sign after going past it for years?"
By Douglas Krantz
The Fire Marshal didn't have the authority to require the owner to upgrade the fire alarm system to use off-site monitoring. Because the building didn't have any off site monitoring, above each pull station was a sign saying "Attention -- When Fire Alarm Sounds -- Call Fire Department -- 911."
Delayed Dispatching of the Fire Department
- Yes, the building did have a fire alarm system
- Yes, the alarm system did sound off
- Yes, this part of the building is a total loss
Any resident hearing the fire alarm was supposed to call 911. But when the fire alarm did sound off, the halls were full of smoke
and the residents of this 8 unit apartment building weren't stopping to make phone calls; they were fleeing for their lives. The fire pretty much took all their belongings.
Will They Call?
It's common knowledge that fire alarm systems
call the fire department automatically. That isn't always true
, but people believe it anyway, and they're surprised when the system doesn't call. Did the residents here even know that the fire alarm system wouldn't call the fire department?
An even more burning question, when the halls were full of smoke and the residents were fleeing for their lives, could they remember to call 911?
Off Site Monitoring of the Fire Alarm
Those at the
Central Monitoring Station (CMS)
aren't near the fire so they don't have to run for their lives. From somewhere else, not on site, they professionally watch the building's fire alarm system. If the fire alarm system sounds off, they call the fire department on a timely basis.
As a method of redundancy, the residents should call 911 anyway. But when residents are fleeing for their lives, having the CMS call the fire department is the more reliable method.
Expense of Off Site Monitoring
Off-site monitoring for a small apartment building is a complicated and expensive proposition.
Most CMSs require monthly or annual charges, this is added to the cost
of getting signals to the CMS in the first place.
- If the building is out of range of fire alarm monitoring radio receivers, there's no help there
- Cable internet isn't all that reliable yet, and there are few fire-certified cable modems
- Cell phone type communication is even less reliable because of the automatic and constant shifting from one tower to another
- Internet monitoring requires the building to use all fire-certified local internet equipment (fire-certified hubs, routers, servers, etc.)
- If plain-old-telephone lines are used, monthly charges on 2 business lines are required
When deciding whether or not to monitor off-site, these cost factors affect the decisions made by the building owners. Sometimes it's considered just too expensive
Cost to Residents -- The Money Question
The cost of monitoring
-- using phone lines, paying the CMS monthly charge, and maintenance -- may well be $90 a month. This is easily the cost whether there are 8 units (like here) or 80 units. Of course, because landlords aren't made out of money, costs like this have to be passed on to tenants.
Question -- to have the fire alarm system monitored off-site, if you were a resident here, would you be willing to pay an extra $12 to $15 a month ($144 to $180 a year) in rent?
Having serviced fire alarm systems for nearly 20, Douglas Krantz has compiled his knowledge of the causes of Ground Faults and how to reliably detect them into the book Make It Work - Hunting Ground Faults
. The book shows the three types of ground fault, what equipment should be used with each type of ground fault, and how to locate those hard-to-find ground faults.
