APC S15 buyers tip


Recommended Posts


Thanks for the heads up. How many S15's are typically used in a system? I realize it depends on how big the system is, but considering a typical 3500-4500sqft install with distributed video and audio.

Thanks,

Glenn

I'm only using one, about 6k sq ft.

Not a whole lot of run time, but keeps the power clean.

I could pull off a few non-essentials and get the run time up over 15 mins.

Or add another and split the loads.

One thing to note, this does not have a serial or IP capabilities for driver via C4 so you can not control it or get status from it.

Add up your power consumption and then check the stats of the S15. Dont trust the manuals (like Denon) as they post the peak start up amps. Most run much cooler. You can buy the $25 kill-a-watt (or borrow mine from me if you want) and plug each item into it and monitor consumption and you'll know. I have 2 s15s plugged into a 2 outlet surgex unit. The APCs don't really have surge protection. They have make-believe surge protection. They are great for filtering and battery backup though. We get lots of lightning storms here and such in Ohio where I'm at so I invested in the Surgex. Watch this 7 minute video if you have time and you'll understand about what I mean with make-believe.

I have no affiliation with SurgeX other than trying to get that IP driver out eventually but 90% of their units are controlled by 12v triggers and not IP (just like APC).

Also, note that it takes an S20 to have IP control via APC but that doesn't mean you cannot control it. Many of the lower units have 12v triggers as well. Thats what those funky looking outputs on the back of your 300 and Extender are for :) You won't get status on those types but you can control it if set up properly.

It can only send signals 1 direction you are right however I'm sure if I sat here and thought outside of the box long enough we could make things happen when power is lost, maybe with the new card access auto reset driver that tests for power outages, if that driver signals a power outage, trigger the 12v trigger on the apc to turn off this bank, then wait 10 minutes and if its still reporting no power trigger the second bank to turn off. I'm not sure. I'd have to think about it but usually with C4 its just a matter of figuring out how to make things happen, not if they can happen.

Granted I'm probably one of the most unlikely salespersons for EV :) but I believe their instructions to the serial driver says to plug the special usb connetion with serial output directly to the 300 (not to a pc). I haven't read through it in a while but I thought thats what it said. I'll buy it for my S15s and post results.

We have used the EV driver with the S20 numerous times and each time I have used the DB9 to DB9 that is supplied with the S20 for communication

Also if you buy an S15 from Vanns and the battery is bad out of box, APC will take care of it all you need to do is call them

The EV serial driver doesn't switch banks like the IP one does but says the following:

"One is for the SmartUPS range of UPSs. This driver provides feedback and event handling from the UPS together with the ability to query the UPS for information."

Theoretically, you could combine that with the 12v trigger from the 300 and should be good to go. Again I'll give it a shot on the 15 and post feedback, espcially considering the Vanns deal with the black faceplate now being offered by APC.

Hi guys

We have two serial drivers for the APC range of UPS. Both use the special serial cable that comes with the UPS - it's wired differently from most. It requires a serial port on your Control4 system to operate.

One driver is designed to work withany of the SmartUPS range of UPS. This allows Control4 to interrogate the UPS for the current voltages, load etc. It also allows Control4 to react when the UPS switches to or from battery power.

The S20 provides all the above feature plus control of the power outlet banks. These you can switch on and off.

I have not tested the S15 with the driver - I know this doesn't have the ability to switch the power outlets though. Given that the S20 uses the same commands as the SmartUPS for monitoring and feedback I would imagine the S15 will also. But as they aren't available in Europe we've not tested it.

I'll still test and report back. Maybe Simon can get me a demo driver to try it. The S15 uses basically the same software as a SmartUPS. EV has a driver that works on plain old SmartUPS series backups (not just the S20) so if I take the USB to Serial that comes with a SmartUPS unit and plug it into the S15 USB port (which also comes with the SmartUPS/PowerChute style software and communicates with a PC over that USB port) and see if anything reads properly.

It should be tried before its dismissed outright as an $80 SmartUPS will work with the 1st of the 2 EV drivers the $800 UPS may as well. I bet its the same protocol among all SmartUPS units except for the S20.
