Rate of Rise: measures
are done along with time
on how temperature is
increasing with time. Unit
C˚/min
Fixed Temperature:
Detect heat at fixed
temperatures i.e. 58˚C
Heat Detector Types
 Point Type:
 Rate of Rise: measures are done along with time on how
temperature is increasing with time. Unit C˚/min
 Fixed Temperature: Detect heat at fixed temperatures i.e.
58˚C
 Detectors complying BS EN 54-5 need to operate on
Rate of Rise with Fixed temperature as a limit for slow
developing fires

Obscuration Method
(Beam Sensor)
TR
 Give false alarms on Dust /
Steam
 Dose not detect small
particles from fast burning
fires
TX
Scattering
Scattering
 Operates on Scattering
principle
 Detect colored big particle
smoke, i.e heated PVC and
other petroleum products
 Practically no life time of light
source
 Disadvantage:

All manual call points, whatever the system, should comply to BS
EN54-11 single action Type A version only and should be located as
follows:
 On all storey exits and all exits to open air irrespective of whether
they are designated fire exits
 Nobody should travel more than 45 meters to reach one, except if
the exit routes are undefined in which case the direct line distance
should not exceed 30 meters
 The above distances to be reduced to 25 and 16 meters
respectively, if there are persons with limited mobility or there is a
likelihood of rapid fire development
 In all areas with potential high fire risk such as kitchens etc
 Where phased evacuation is planned, call points need to be sited
on all exits from a particular zone
 1.4 meters + or – 200mm above the floor

System Design: Loop Power & Length Calculation
Conditions
 Each Loop can drive up to 500mAmp
 Detector during alarm consuming more current than
normal status
Sounder is draining the highest current in Loop
Handy Software is provided for Loop Calculation
System Design: Steps
1- GET THE REQUIREMENT (FA/FA+FT/FA+PAVA/FA+FT+PAVA).
2- COUNT THE NUMBER OF DEVICES REQUIRED IN YOUR PROJECT.
3- CALCULATE THE NUMBER OF LOOPS BASED ON 240 DEVICES PER LOOP.
4- CALCULATE THE NUMBER OF FIRE ALARM PANELS BASED ON THE NUMBER OF
LOOPS PER PANEL.
5- CONSIDER THE NUMBER OF LOOP DRIVERS BASED ON THE NUMBER OF LOOPS
PER PANEL
6- CONSIDER NETWORK CARD IN CASE MORE THAN ONE FIRE ALARM PANEL IS
CONSEDERED IN YOUR DESIGN.
7- CHOOSE ON BOARD PRINTER WITH VARIES OPTIONS (OPTIONAL)
8- BASEDON YOUR BOQ CONSIDER THE FOLLOWING LOOP DEVICES:
>LV/V100 SMOKE DETECTORS.
>LV/V200 MULTICRITERIA DETECTOR.
>LV/V 350 HEAT DETECTOR.
>VB100S STANDARD DETECTOR BASE FOR ALL TYPES OF DETECTOR.
>VCP100 INTELLIGENT RESETABLE CALL POINT RED
>VLS100 INTELLIGENT WALL SOUNDER.
>I/O MODULES (DEPEND ON THE APPLIANCES NEED TO BE CONTROLLED OR
MONITORED.
9- FIRE TELEPHONE/ PUBLIC ADDRESS & VOICE ALARM SYSTEM.
