Home Forums General Discussion Technical Questions Tac22 Fire Service fault

Hi everyone, new around here, i have this tac 22 that wont reset fire service after a board replacement, it goes into fire service and Ph2 works but when you reset it it doesnt reset at all, you can see input fsh2 and fsh5 goin on and off (those are the inputs for Ph1 off and reset).
if you power cycle it the car goes to automatic operation but group service still shows as fire service and wont reset even though its seeing input FSH5 come on for the reset. any help or suggestions with this are appreciated.

Is FSC2 high in the car?
And can you see the IOs change state in the group IO map? Also make sure there aren’t any other FSH IOs anywhere in the group. There could be IOs for a secondary fire service switch. Was the 188e replaced? If so were you able to get the job cfg file out of the old board to put in or was it an in-adjusted job file?

Yes FSC2 is high

See my edited post

Yes i can see the IOs switch on the group IOs and the car IOs, now that you mention it i do have FSH3 and FSH4 on the group IOs which are unused but they are there, the job as far as im aware shouldn't and doesn't have a secondary fire switch. the 188E was replaced before, I dont know if they got the cfg file (i wasnt on this area when that happened) out of the old board but i do know they used the job file from a CD. if i need to remove those IO can i do it through ims?

Ya, just right click on the IO, click add or change an IO, delete the IO name. You won’t see the changes until you write it, reset the CPU, and reload the the network in the control panel.

Ok I’ll try this today and keep you updated, thanks for the help!

When I right click the IO the only options I get are: HELP on IO, metered logic, positive logic, display 8 bit ports, 16 bit ports, connect to virtual scope, hide show unused columns and enable IO injection I have IMS 2.4

Ya you need better IMS

Alternatively, lay out your group IO map on top of the car’s and line it up so the FSE FSX FSM columns are right on top of each other. Post a pic and we’ll figure out where to jump out FSH4. Or that may be in the original print. To temporarily clear FS you could inject FSH4 then reset at the switch.

This should make more sense:

Car/Group IO Alignment

I managed to get it working, jumped FSH4 to G24 and the reset the fire service and it worked.



Where can I get a newer version?

Thank you idwt. Very informative.
