FireRanger, it sounds like you install Fire Systems rather than Engineer them. It is comendable that you can just replace the conventional ones but most contractors would need to be paid for this type of expense, especially if you had 18 or 20 of them and the Electrical Engineer knew that Div 15...
Your right it is not appropriate and they are "Cheesy" but they are UL listed for door release and under NFPA 72 (2002) 5.14.6 it addresses this and the exception under 6.15.6.2 is an interesting piece of information. I would rather stay away from them completely and use the system detectors...
I do have the IFC 2000 but I also have the new one 2003 and the IBC and the 2002 NFPA 72. Apparently according to the code there is an option to even connect the dampers. "If" they are connected are the words used. I was trying to find somewhere that said you had to connect Dampers to the FACP...
The D6680-E120 Converts the Serial output of the D6600 receiver to an IP based format that can be used over a network. The D9133TTL-E module only works with the Bosch 9000 series panels and the C900TTL-E works with any panel. It captures the information from the dialer and sends it over the...
You are so right, problem is many Engineers and Contractors here are not updated with the new technology and it is like pulling teeth to get everyone to change. Thanks again.
GOTWW,
Using the proper wiring and an RJ31X block the Fire Alarm Contractor can have the FACP seize the line. Many fire marshals in our area require that the Primary is dedicated and the Secondary can share but will sieze the line in the event the primary is not functional. Rbulsara has good...
Sorry if I was misunderstood, you are correct that the door holders need not be supervised and they do not need to be on the same power source although if they are tied to the FACP directly then they close on alarm. What I meant, is that electrical contractors will power door holders separately...
From what we have learned, if you use 120 volt smokes tied to the door closers they need to have a battery backup and they need to be recharged. Yes you are right if you have a fire panel it makes much more sense to tie 24 volt detectors to the panel. Your right about the same power source but...
We are in Utah, there is no requirement for Fire Alarm Licensing at all. It seems that many of the Fire Alarm Companies just go off the Electrical Contractors permits since the EC is installing the Fire Alarm and the Fire Alarm Contractors are just selling the EC the equipment and programing the...
I see your point. Without coordination it could get left out. With an Analog System the Duct Detectors really should be provided by Div 13 so you get sensors that can report when they are dirty and how dirty they are. The standard detectors don't provide all the extra information. I guess we...
Each area seems abit different but here in the West many Electrical Engineers specifiy that the Duct Smoke Detectors should be provided by Div 15, installed by 15 and monitored by the Fire Alarm Contractor. After the Analog Addressable technology came out and many of the panels will allow you to...
I have ran into the same concern where our state has only adoopted the IBC 2000 and many Engineers here in the State place IBC 2003 on the plans. What to do? Good questions and concerns.
I kept looking on this one and this is what I have found, please let me know if you have additional input. CONDUIT is not required if you installed low voltage power limited circuits with FPL, FPLR, FPLP or CMP wire. If you use THHN wire it must be in conduit from Chap 3 methods for non-power...
