But I dont want to use som also I want to install many horn within a panel which will work automatically. Suppose i am using 4 SOM in a building.

They can be installed remotely in the building so wire distance and voltage drop issues are reduced.

Home Shop Store Contact us. Will this connection work? This has to be decided by knowing what is connected to each SOM, how much current is being used, and if that is in the capability of the power supply. Again, the amount of devices depends on the device’s rating, wire gauge, current draw of each device, etc That means when detectors detects then all horns will sound automatically but not supervised.

But As far i know that when detectors detects then it passes a signal towards the panel and after a mentioned time panel pass a signal to NAC and NAC will generate power through the notification devices and alarm generate. Post Sun Mar 05, 3: Depends on a lot of variables, including the wire gauge, wire length, and current draw of each device as well as the limitations of each NAC and combined NAC’s.


With 4 amp current we can only connect a few horn strobe. Why SOM is used? Yochiki the NAC extender has its own power supply it does not draw power from the main panel. Then the horns connected with the power supply get power from this external power supply when the relay gets power from NAC. For manual call point placement inside SLC loop what control module is used? These are a separate box with a power supply, battery charger, batteries, hofhiki NACs.

I know that if I use som module then I can conncet many horn within a panel. The current used by each NAC has to be added up and cannot exceed 4 amps total. I don’t have any practical experience.

Thanks for your reply.

According to the manual I downloaded there is an addressable manual station. I don’t know i am right or wrong.

These outputs may be used for a variety of purposes including door holders, elevator recall, and other fire safety functions. One NAC at 1. Am i right or wrong please explain. From the Hocyiki installation manual: Events are reported to a compatible central station monitoring receiver.



Post Wed Mar 01, 7: As it says in the manual about fn-217 SOM: That’s why i am confused. You cannot just throw some relays and generic power supplies in the circuit. If you used a normal relay to switch power on and off to these devices, then you would have no way to monitor the circuit, which is why the SOM exists. The device address is uniquely stored on an onboard.


Can you give me a diagram of your suggestion? Post Wed Mar 01, 1: They can be installed by the main panel or remotely in the building as needed.

Post Sun Mar fn-227, 7: Post here if you need help dn-2127 something related to fire alarms. To use a standard contact type call point there is a selection of modules shown in the manual.

Can i directly connect sounder base in a SLC loop?

NAC only can supply 4 amp only. Post Sun Mar 05, 6:
