Ziton ZP3 addressable fire alarm system show unaccepted point fault signal - how to resolve this ?

You could google the company and look on there wed site .

being a 50cc engine it should have only 1 piston
If it is a 2 stroke , it will fire every time the piston comes to tdc
if it is a 4 stroke it has to have a timing point that excites the ignition system for every 4th stroke tdc
if the exciter receives a signal to fire the plug at the wrong time , it is getting that signal from a fault or incorrect timing
that fault can be
loose wire/s,worn unit that controls the timing ( distributor fault), loose flywheel , flywheel touching coil,incorrect timing (180 degrees out ) stator loose ,rotor loose,faulty crank position sensor
it is good practice to have a workshop manual on hand and if you don't have one go google and type in --workshop manual for 50 cc tao scooter--and see if there is a pdf version in english to download

Temperature alarm
If the temperature becomes too warm, an alarm will sound and the temperature display will flash. The temperature the appliance is set at will determine when the alarm is triggered.
The alarm will sound and the display will flash under the following conditions:

• - whenevertoomuchwarmairflows into the appliance, for example when food is being loaded, re-arranged, or taken out.
• - wheneverlargeamountsoffoodare being frozen at once.
• - whenevertherehasbeenalengthy interruption of the power supply. Door alarm
  If the appliance door is left open for longer than approx. 60 seconds, the alarm signal will sound.

Switching the alarm system ON
The alarm system is always active. It does not need to be switched on manually.
Switching the alarm OFF early
Once the set temperature has been reached in the freezer section, the alarm signal stops and the temperature display stops blinking. If the alarm signal bothers you, it can be switched off early.
^ Press the alarm off button. The alarm signal will stop. The temperature display will continue to blink until the set temperature has been reached. The display then stops blinking, and shows a steady reading. At this point, the alarm system is ready again if needed.

1.Check all your cables for faults.
2.Check that you have the drivers for your internet connection installed on your laptop,desktop. If not re-install.
3.Try re-setting your router.

Line fault sounds like it is not getting enough power. Check the transformer to make sure it is outputting the power it says it should. If you don't know how to do this, then don't check it and find someone that does know how. (to avoid shock)
The other point is that maybe zone 3 is not adresses or has a battery failure if battery is present.

types of fire alarm systems:

Your smoke detectors, heat sensors or fire pull stations (depends on what is installed in your system) are located on your 4 zones. The wiring that connects these sensors to your fire control panel is supervised by an end-of-line resistor. Starting at the panel all wiring on that zone is daisy chained between each detector with the resistor being placed at the last detector. The panel looks for this resistance value at all times. If one of your detectors goes into alarm this creates a short. This is how the system recognizes an alarm state. Conversely, if there is break in the wiring the system fails to see any resistance and the panel will indicate a problem or trouble condition. The most likely cause of your 2 problems is either broken or cut wiring, ie; the system no longer sees the end-of-line resistance. If you are handy and have access to a multimeter you can measure resistance along the zone loop by disconnecting the zone wires from the panel and measuring wire resistance from each detector to the last one. Most Firelite systems use a 4.7k ohm resistor so you should see this at the zone wiring from the panel. If you don't, try removing a detector somewhere in the middle of the circuit and try again. Once you find a detector with that resistance your problem lies between that detector and the panel. It is just a matter of isolating the problem by measuring the zone resistance along different points of the zone wiring. If you are not comfortable doing this by yourself then I would suggest getting either an electrician or fire alarm tech to track down the problem. Hope this helps.

An "earth fault" or ground fault is a condition where one of your circuits is grounded or shorted to earth. While all fire alarm systems are normally grounded for circuit board overload protection and personal safety issues, all circuits (bell circuit, smoke detector/heat detector/pull station circuits) should be free of earth grounds. I would suggest if you are not knowledgeable enough to troubleshoot your system you should contact a security/fire alarm installation company to fix the problem. If this is not a viable solution and you want to attempt this on your own try removing each circuit from the panel one at a time. While this will certainly cause additional system troubles, when you remove the circuit causing the earth fault the condition will disappear. You will then need to check all wiring, spice points and devices on that circuit to determine the faulted location.

Open your alarm cabinet, inside is a battery. Replace it with the same sized battery. it is probably a 12V 7ah battery. You should be able to find one for less than $30 locally.
