'The rest of the story...'

City of Las Vegas to Alter Response to Fire & Medical Alarms 

In a move to save taxpayers money and to prevent fire and emergency
medical crews from responding to false alarms, Las Vegas Fire & Rescue
has modified its response procedures to incidents that are received
through automatic alarms or through an alarm monitoring company.

Fire Chief David L. Washington made the changes after fire crews
reported that an overwhelming number of responses to automatic fire
alarms and medical alarms are usually false and did not require the
services of the fire department.
 
One of the main concerns is in the area of medical alarms. Many people
in the valley subscribe to a service in which a company checks on those
with medical alarms every few hours. If the party does not reply, the
company, which in most cases is located out-of-state, calls 9-1-1 and
reports a medical emergency. Many times the people are either shopping
or are out of town on vacation and did not report to the monitoring
company that they would not be at home. When emergency medical crews
arrive on the scene, they are not sure if someone is hurt inside and
cannot open the door or if the house is vacant. If medical crews decide
to break into the house to check for an injured person and no one is
home, damage is done to the house and the city is responsible for
securing the house and making repairs. In the case of panic alarms
(where a person presses a button to request an emergency response) crews
will respond immediately. If the call turns out to be false, the company
that sent in the alarm is subject to citation per the City of Las Vegas
Fire Code.

The same is in the case of fire alarms. Many times smoke alarms will
activate false alarms and as many as five units are sent to investigate.
With units responding with lights and sirens, there is an increased
chance of being involved in an accident. It also leaves an area of the
city unprotected.

The new procedure will require property owners to have someone check out
the premises to see if a fire is actually in progress. Many alarm
companies have response teams that will check out the call and notify
authorities and the property owner. In the case of automatic fire
sprinklers, fire crews will still respond if an alarm is received that
automatic fire sprinklers are activated. If the call turns out to be a
false alarm, fire officials may issue the business owner a citation
because of a false alarm.

Under the new procedure, someone will have to actually verify that a
fire is in progress before crews will respond. In some cases alarm
companies reported that they had personnel on the scene to verify the
alarm, when in fact they didn't. Under the new procedure if the alarm
company reports they have personnel on scene, and they are not on scene
when firefighters arrive, they will be given a citation and fined for
reporting a false alarm.

Fire alarms are required by fire code to notify the occupants of the
building to evacuate because of fire, and in only certain cases are
required to notify the fire department of the fire. To notify the fire
department, the code requires occupancies such as hotels/casinos,
hospitals, detention centers and the like to have their fire alarm
system monitored by someone that can confirm the fire report and call
the fire department. Fire and smoke alarms in homes are only required to
notify the occupants of the home of the fire, they are not required by
code to notify the fire department. But in many cases, people have
contracted with a monitoring company to notify the fire department that
the system has been activated. Many companies are located out-of-state
and cannot confirm whether a fire actually exists in the home.

Recently fire crews have reported that alarm monitoring companies
dispatched them to burglary and robbery calls before police were
notified, endangering firefighters and putting them in a dangerous
situation without knowledge of the actual circumstances of the call.
Recently one crew responded to a reported house fire. While checking out
the house, police officers arrived with guns drawn. The firefighters
were told it was actually a burglary in progress and there was no fire.
The new procedure is expected to save thousands of dollars in
unnecessary responses and to keep fire and emergency medical crews
available for actual emergencies instead of false alarms.

NICET(r) Fire Alarm Systems Level I
Element 31008^ BASIC MATHEMATICS
-------------------------------

31008 DESCRIPTION:
"Solve mathematical problems requiring simple addition, subtraction,
multiplication, division, and raising numbers to exponential powers.
Round to the correct number of significant figures, calculate
percentages, read graphs, and use simple geometric definitions and
formulas. (See general mathematics textbooks)"

31008 is a General Non-Core Work element.

The caret (^) following 31008 means generic crossover credit. Once you
pass this exam element, you will receive credit in other
fields/subfields.

31008 REFERENCES:
General Mathematic Textbooks

31008 DESCRIPTION BREAKDOWN:
"Solve mathematical problems requiring simple addition, subtraction,
multiplication, division,...

2 + 2 = 4
4 - 2 = 2
2 x 2 = 4
4 / 2 = 2

(a/b) + (c/b) = (a + c)/b
(a/b) + (c/d) = ((ad)/(bd)) + ((bc)/(bd)) = ((ad) + (bc))/bd
(a/b) - (c/d) = ((ad)/(bd)) - ((bc)/(bd))
(a/b) x (c/d) = (ac)/(bd)
(a/b) / (c/d) = (ad)/(bc)

"...and raising numbers to exponential powers.

3 x 3 = 9 can be written as 3^2 = 9

3 x 3 x 3 = 27 can be written as 3^3 = 27

3 x 3 x 3 x 3 x 3 x 3 = 729 can be written as 3^6 = 729

2000 can be written as 2 x 10^3

0.002 can be written as = 2 x10^-3

9 can be written as = 9 x 10^0

Rule for Multiplication: (x^n)[times](x^m) = x^m+n 
Rule for Division: xn / xm = x^n-m 
Rule for Raising a Power to a Power: (x^n)^m = x^n[times]x 
Negative Exponents: A negative exponent indicates that the power is in
the denominator: x^-n = 1/x^n 
Identity Rule: Any nonzero number raised to the power of zero is equal
to 1, x^0 = 1 (x not zero).

"Round to the correct number of significant figures,...

Rules for assigning significance to a digit: 
1) Digits other than zero are always significant. 
2) Rules about zeros: 
   a. Final zeros after a decimal point are always significant. 
   b. Zeros between two other significant digits are always significant.

   c. Zeros used only to space the decimal are never significant.

Look for the first non-zero digit. It and all digits to its right are
significant.

"calculate percentages,...

Percent is one part in a hundred.
Percentage is a part of a whole expressed in hundredths

If you receive a wage increase of 2% and you are currently earning
$20.00 per hour, what is your new wage?
2% = 2/100 = 0.02
0.02 x $20.00 = $0.40
$20.00 + $0.40 = $20.40

If your wage increases from $20.00 per hour to $25.00 per hour, what
percent increase did you receive?
$25.00 - $20.00 = $5.00
$5.00 / $20.00 = .25 = 25%

25% = 25/100 = .25
125% = 125/100 = 1.25
1% = 1/100 = .01

40% of 80 = .4 x 80 = 32
17% of 42 = .17 x 42 = 7.14
1% of 1000 = .01 x 1000 = 10

32 is what percent of 80?
32 / 80 = .4 = 40%

7.14 is what percent of 42?
7.14 / 42 = .17 = 17%

10 is what percent of 1000?
10 / 1000 = .01 = 1% 

32 is 40% of what number?
32 / .4 = 80

7.14 is 17% of what number?
7.14 / .17 = 42

10 is 1% of what number?
10 / .01 = 1000

"read graphs,...

Sorry, I don't have the skill-set necessary to display useable graphs
with ascii.

...and use simple geometric definitions and formulas."

The area of a square (a four-sided polygon with equal sides) or a
rectangle (a four-sided polygon with equal opposite sides and four right
angles) can be determined by multiplying its base by its height:
A = b x h

+-------+ -
|       | ^
|       | |
|       | h
|       | |
+-------+ -
|<- b ->|

The area of a square with base = 2 and height = 3 is:
A = b x h
A = 2 x 3
A = 6

The area of a triangle (a three-sided polygon) can be determined by
multiplying 1/2 time its base times its height:
A = 1/2 x b x h

|<- b ->|

The area of a triangle with base = 2 and height = 4 is:
A = 1/2 x b x h
A = 1/2 x 2 x 4
A = 4

The area of a circle can be determined by multiplying the value of pi by
the radius of the circle squared:
pi x r^2

|                |
               /
  `._        _.'
     `-....-'

The area of a circle with a radius of 4 is:
A = pi x r^2
A = 3.14 x 4^2
A = 3.14 x 16
A = 50.2

The area of a parallelogram (four-sided polygon with opposite sides
equal can be determined using the following formula:
A = b x h

    +-------------------+ -
   /                   /  |
  /                   /   h
 /                   /    |
+-------------------+     -
|<------- b ------->|

The area of a parallelogram with base = 4 and height = 2 is:
A = b x h
A = 4 x 2
A = 8

The area of a trapezoid (four-sided polygon with two parallel sides
(bases)) can be determined using the following formula:
A = (1/2(b1 + b2)) x h

    |<--- b2 -->|
    +-----------+ -----
   /                 |
  /                  h
 /                   |
+-------------------+ -
|<------- b1 ------->|

The area of a trapezoid with base1 = 4, base2 = 3, and height = 2 is:
A = (1/2 x (b1 + b2)) x h
A = (1/2 x (4 + 3)) x 2
A = (1/2 x 7) x 2
A = 3.5 x 2
A = 7
