3 maintenance items on a cont. loop system
supported every 8-10 inches
bend radius 3``
No crushing , kinking, or chafing
what are the 3 types of of ssmoke detectors
what are 2 common extinguishing agents used in aircraft
What does a missing red disk indicate
Over temp pressure discharge
What does a missing yellow disc indicate
Shows a system discharge
what is a HRD use for suppressant
how does a HRD use activate
an explosive squib breaks the flangible disc and releases
how do you check the level of extinguishing agent in a HRD
weighing the tank
true or false , Squibs are life limited
true or false , CO detector buttons are life limited
2 types of CO detectors
what is used as a propellant in a CO2 system
why is orienting fixed CO2 bottles important
if not oriented correctly , the pickup may not be able get all CO2
What test must be done on all CO2 bottles every 5 years
Which loop detection circuit uses Ceramic beads?
How many electrodes are used in a fenwall continuous loop?
1 center conductor and inconel tubing is used for ground
In a fenwall loop circuit what are the glass beads covered with?
How many conductors are in a kidde loop system?
2 , one positive and one ground, also inconel tube is ground
what is the material surrounding the center conductor in a kidde loop system called?
Thermistor or thermal resistor material
of the pnuematic loop systems , which one is flexible and bent by hand?
Lindberg, Systron-Donner is rigid
When checking routing of loop systems in hinge-clamped lines what must be looked at?
that the insulators split is toward the outside of the bend
What is the proper distance of the clamps supporting a loop system?
What does a jetcal analyzer do?
used to physically test a sensing element by applying a known heat to see when the alarm is activated
What is a example of class A fire zone?
Recip engine compartments
What is an example of a class D fire zone?
Wheel well or inside of wing (little or no airflow)
What are the 3 continous loop systems?
What is the benefit of a meggitt loop system?
If the loop breaks and the gas escapes it gives a fault indication
On the lindberg loop system what is the pnuematic bellows assembly that senses pressure increase called?
In a loop system what is the metal called that absorbs and releases gas?
Which spot system uses thermocouples?
What is the benefit of a double loop system?
if the positive side grounds out , it switchs polarity and still works
