So originally I worked through the manual, then wired it all together
Zone 1 PIR
Zone 2 PIR
Zone 3 PIR
Zone 4 wireless door
Zone 5 wireless door
Zone 6 not used
Zone 7 not used
Zone 8 smoke

So when I first hooked it up it seemed to be working fine delay exit and entry so I finished programming it with selections we had chosen and the entry delay quit working. So I was resent everythign to default and started troubleshooting and I have it working until I add the 3rd motion detector. As soon as the zone 3 PIR (which is also the only one different of the 3) is connected I tested it and the entry delay is gone again. Any suggestion I have tried eerything I can think of. Please Advise. Thank you

The entry 1, entry 2, exit, and bell time is 1 string of digits,
What zone is your entry and what do you have it programmed as, 01?
If you are not using an alpha keypad, programming can be confusing, interpreting the leds.
Did you Enroll the Keypads? Enable supervision?

I assume ALL your zones are wireless? If so go into fields 101, 102, 103, 104, 105, 108 and make sure number 8 is turned on. That is what actually turns on the wireless for the zones.
Any time you make changes within the one attributes it's best to go back and double check the wireless zones are turned on.

A step by step an example on how to program exit delay in pcs power series pk5500.

You need installers code, and you use *8 CODE, not *6 CODE which is users.
Can you get into programming and do you have the Manual.
Then go to Location 005 and enter the String of digits which includes entry 1, entry 2, exit delay and bell cuttoff time.
Can you get into programming ?
Do you have the Installers Manual?
