Hi forumities,
Some times, when there is a troubles on EST3 panel caused by a detector, I open the detector from base, clean it and re-install in again and reset the panel and the troubles is removed. But some times the troubles is not removed, so I disconnect Battery & AC power and turn the panel off and after 60 seconds turn it on. and then the troubles is removed. I don't know if this technical or not but it works for me and helps me to remove some troubles, will it make problem for my panel?
The problem is that after one year, my panel power supply(3-PPS/M-230) went in problem, and I replaced both power supply & monitor module, Again 6 months later the panel power supply went in to problem (Showing AC Brownout message) and I replaced monitor module again and problem fixed. Was this problem caused because of turning off the panel explained above?
I would appreciate if you share your valuable experience on this issue.
Thanks,
Reza
EST3 -Removing troubles by disconnecting Battery & AC power?
Re: EST3 -Removing troubles by disconnecting Battery & AC po
Hi,
AC Brown Out will come into picture when the main supply (230VAC) to the panel is turned off..............
Actually after troubleshooting sometimes you need to restart the panel from the menu so as to make the panel Green/removing trouble.Whereas you are also doing the same in more conventional way.
let me know whether it worked or not.....

Hi guys. I just want to ask if I can replace power supply 3-PPS/230-M with local rail module without reprogramming. Thank you so much..

hi is the mapping enable, because when you put back the detector the mapping check the loop and is it everything ok is not need to reset, what version of sdu,bootloader and code have.

Re: Removing troubles by disconnecting Battery & AC power?
It sounds like you are cleaning dirty smoke detectors, I have had a lot of trouble cleaning dirty detectors.
I think it takes 24 hours for the environmental compensation to reset.
How to Determine when a Photo Detector is dirty– EST3:
If you use SIGA-PS, SIGA-IPHS, or SIGA-PHS the EST3 system will display ”Device Maintenance Alert” (0675 Loop 1 or 0685 Loop 2) condition at the 3-LCD/3-CPU(1) when the Photo portion of detector needs maintenance. Running a report for “Dirty Head List” will generate a list of all devices and their dirty levels.

Re: Removing troubles by disconnecting Battery & AC power?
Yeah, mapping enabled, my SDU is 3.61.
Thanks Leo for the note.
My question is that if disconnecting Battery & AC power and turning off the panel twice/month will harm power supply(3-PPS/M-230)?
My client is accusing me of harming the panel as we have replaced two power supply during a year.
Thanks,
Reza

Re: Removing troubles by disconnecting Battery & AC power?
It maybe do to you powering it down and up, put that is life.
How are you going to service any problem without power cycling a system now and then.
Also I have not got a (AC Brownout) from power cycling a PPS, I blow the fuse in one.

Re: Removing troubles by disconnecting Battery & AC power?
Thanks,
would you kindly please explain more if I was guilty or not.
Will turning off & on the panel twice/month will harm power supply(3-PPS/M-230) or the control module?
Best,

Re: Removing troubles by disconnecting Battery & AC power?
hi these are the steps i do when i powerdown any fire panel:
-discconect battery
-turn off the main braker
for power on
-connect battery
-turn on main braker
just a tip
regards...

Re: Removing troubles by disconnecting Battery & AC power?
Hi FVILLA,
Thanks. But I think for for power on we should turn on main braker and then connect battery.
This is the email I received as an asnwer to my question, I think it is helpful for forum.
Reza,
Removing and re-applying the power shouldn't cause a problem. You'll want
to remove the Batteries first, followed by AC and then reverse the order
when powering them backup (i.e. AC first then Batteries). This is done as a
precaution to insure that any spikes that occur when connecting the AC don't
cause problems with the batteries.
It's been my experience that the incoming power is usually the problem.
Unfortunately the only way to verify this is to use a storage scope, which
is something that most fire alarm companies don't have. We us a software
based scope and are able to record information of a span of time.
A look at your web site and I see that you're in Iran, which has me
wondering about the quality of the power. While I haven't done work in
Iran, I've done a lot of work in the Middle East and Africa for companies
that have their own power generation and use it to power their panels. I've
also been involved in several US Embassies that take their power off of the
local grid and have backup generators on property. In the US and Europe the
power is fairly stable, but not always. In underdeveloped countries the
power can be all over the place. At sites where the client generates their
own power, it isn't always perfect. One site in Central Africa, owned by a
major oil company, had one of the many panels constantly loosing, or
corrupting, it's program. While this may have to do with the way in which
the power supply is manufactured the issue was the quality of the power. We
had them install a power conditioner and since then they've had no problems
with this panel.
Understand that fire alarm manufacturers don't supply rock solid power
supplies and transformers. They'll supply, or design, a unit that meets the
minimum requirements for the least amount of money.
Some suggestions might be:
1. Consider the time of the occurrence. You may be able to see this
from a history log from the panel. If it's in the morning when the local
population is getting up to go to work, it would seem to point to the power
condition.
2. If you don't have a storage scope, use a volt meter and simply keep
your eye on the AC voltage for several minutes. While this isn't perfect,
the problems will usually occur when the local populations is getting up in
the morning to go to work, or when the office building the panel is
installed in, starts to come to life with the work force coming into work.
3. If you can convince the client to pay for a power conditioner, try
that. A SOLA power conditioner, rated at 5 Amps, will run about $500.00 US.
4. Consider the events at the time of the occurrence. Was there
lighting outside?, Did a piece of equipment with a heavy current draw
startup? If there was lighting, install a lighting suppressor, but make
sure It's properly grounded or it's pointless. Also make use you understand
grounding principals to make sure you're efforts to ground the system aren't
in vein.
5. Check to see if the power supply is properly grounded. Just because
there's ground wire on the power supply, doesn't mean it's grounded at the
other end. Measure the resistance to ground on the ground conductor. It
should a less than 300 ohms (200 is better) if it's properly grounded.
6. You may want to examine the failed power supply and see what's
damaged. If it's a Capacitor, or a Bridge, it would seem to point to the
incoming power. If it's something else, well.
As a last resort, ask your client if he/she, has a degree in electrical
engineering or electronics, and if he/she does, see what they have to
suggest, if not.tell him/her to shut up, stand in the corner and have their
wallet open.just kidding on this last part.;-).don' t say that unless you own
the company, or the owner of the company doesn't want the clients business
anymore, or if it's a military installation.
