I am looking for smoke detector for my motel due to covering the old ones with plastic bags. i was wondering if i would have the same problem with a smoke detector with a pulsing led sensing chamber?

for the correct smoke alarms to use , go talk with your fire brigade officer or fire department
there are 2 types that use batteries and in some countries with an accommodation type of business the alarms have to be hard wired to a central alarm system that automatically calls the fire station

I have 6 smoke detectors & two CO2 detectors hardwired in. The smoke detector in the kitchen went off and now all the detectors will not stop alarming. How do I reset?

First of all, you really should not have a smoke detector in the kitchen as it will be far too prone to false alarms, especially since most household smoke alarms are ionization type, which respond to the presence of gases caused by combustion. A proper system as recommended by NFPA will have one detector in each bedroom, one in each bedroom hallway, and recommended one per floor thereafter, with placement being near exit points to help guide you to the exit during an actual fire (by sound, since it's difficult to see through smoke). I would be inclined to remove that device or try to find a heat detector replacement, such as Kidde Model # HD135F. For now I would vacuum out the device or try a can of compressed air to blow it out, but I would not leave that device long term.

The sensor Honeywell TC807A 1036 (Smoke Detector), is compatible with a NFS-320 Fire Alarm Control Panel?

I don't know if that particular smoke is compatible or not, but the NFS-320 is a commercial rated UL864 Revision 9 fire panel, which means the documentation is part of the UL listing. This means that in order for a device to be compatible with the system, it must be listed in the Installation Instructions as compatible. I couldn't find any mention of that particular smoke in any of the documentation I found for that alarm panel.

Hi,i need to fit two wired fire alarms and one heat they have to be coonected from fuse box or just from a light bulp

Generally, hard wired smoke detectors are wired in series. That way, if one alarm sounds, the other will too. Thereby, alerting everyone throughout the home or office. They should be wired with their own circuit breaker. Also, most hard wired smoke detectors have a battery backup, in case of a power outage.

My best advice ... If you don't have the Owners/Installation Manual, search for it online using the manufacturer's name. Better to be safe than sorry.

Fire alarm panel showing problem on 2 zones

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.
