How do I setup my Apex to notify me of a power failure?
The Apex base unit and the EB8 module can each detect power interruptions and you can test for this in your
email alarm outlet program. The key to being successful here is to keep power to the base unit and your network equipment long enough to send the email. The base unit accepts power from two sources - the EB8 via the USB looking AquaBus connection or
via a DC adapter (Neptune P/N PS12, 500ma output, 12v, 2.1mm tip, center electrode positive). To insure you keep power long enough, get a small UPS. It only needs to be big enough to power the base unit, your router and modem and your PC (assuming you don't use a laptop). A UPS in the 300 - 500Va capacity should be more than enough.
In the configuration → outlet setup page, the following statements for the emailAlm (email) or the SndAlm (audible) outlets should do the trick (example assumes you have a single EB8, number 3):
Set OFF
If Power EB8_3 Off 001 Then ON <--this detects if the EB8 loses power
If Power Apex Off 001 Then ON <--this detects if the base unit loses power
You might wonder, if the base unit is on a UPS, how would the "If Power Apex" statement ever be true. Normally it wouldn't, the UPS will prevent that unless of course its battery fails. But anytime you reboot the base unit, it is momentarily without power and will recognize that as a power failure, triggering the alarm condition. If your base unit reboots on you during the middle of the day, you’ll know about it. Of course, the EB8 gets its power from the wall and would note any normal power interruption. If you wanted to limit these emails to only if the power has been out for a couple of minutes, you can use the new Defer command.
Version: 5.0 Page 142
Beginning with release 4.03 a new option has been added to the System –
Misc Setup menu. Called Power Monitor, this option will enable the base unit to sense a loss of power on the supplemental 12v power port. This gives you the ability to put
your EB8 on a UPS and plug the 12v adapter into a regular wall outlet. If power fails, the ‘If Power Apex’ statement will detect it while the UPS provides uninterrupted power to the EB8 and through that, the base unit. The default for this option is ‘OFF’ so make sure you set it through the display module if you want to use this feature.
After sending you the email alarm, the Apex will wait a short while before sending another email message to avoid streaming dozens of emails to you regarding the same condition. This delay, known as the “re-email delay” is defined in your email configuration in the
configuration → network setup page. You can set it to however many minutes you want. The default is 5 minutes.
