Essential tips for working on paging and emergency call systems

When a buyer switches to VoIP, what ought to be completed with an outdated analog paging system? Tech knowledgeable Bob Dolph focuses on a handful of sources.

If a dealership is seeking to diversify their enterprise or a low-voltage technician is seeking to develop their technical abilities, one space that is at all times busy is audio programs. On this column, I primarily check with paging programs and their cousins ​​resembling mass notification and emergency name.

This month, we’ll be taking a look at suggestions and recommendation on older and newer analog units. VoIP (voice over web protocol). I used to be stunned at what number of older analog programs are nonetheless in use. I assume the outdated adage, “If it ain’t broke, do not repair it,” might come into play.

First, I want to pay tribute and congratulations to a valued audio programs provider, Viking Electronics. I’ve recognized them for many years and in my eyes they’re the true reference supply for designing and equipping audio programs. I will be referencing many helpful sources from Viking, together with a number of the suggestions they’ve collected over time.

If you want to increase your level of expertise with sound systems, I recommend you do the same. You might want to start by checking out the Viking website and their Youtube channel. Now let’s dive deeper into a few of these programs.

Swap to VoIP

One of many greatest areas of technical assist calls at Viking is round new applied sciences resembling VoIP. I do know many within the alarm business have seen phone firms transfer from legacy analog phone programs (POTS) to digital VoIP. Many have additionally seen that it could actually happen on major phone firm cellphone traces with little or no warning to the shopper or the supporting alarm expertise firm.

When a buyer switches to VoIP, what ought to be completed with an outdated analog paging system? Do I’ve to rewire the entire system? No, chances are you’ll need to think about one of many many Viking digital choices. One gadget to contemplate is the PA-IP, a SIP/Multicast paging adapter with amplifier. The gadget is PoE and powers as much as six analog audio system or 10 multicast paging teams.

One other useful gadget if you wish to convert current analog ceiling paging audio system to VoIP is the PSA-IP IP Paging Speaker Adapter or PSA-TB-IP IP paging voice adapter with talk-back (see Device of the month).

As we mentioned earlier, making VoIP applications posed many technical problems. Here are some key areas suggested by Viking to look out for BEFORE switching to VoIP.

  • Overhead Paging — Not all systems support an FSX port and you may need an FSO port.
  • Door Entry Phones – How does this phone get in and make a call? Does it use an analog phone line or an extension. Does it attach to a chest? Is there a controller in the middle of everything that needs to be programmed?
  • Fax — Make sure it works with other VoIP devices.
  • Elevator Phone — Does the mobile cable have CAT wiring? Otherwise, stick with analog and try to get the FSX ports from your provider.
  • AOR (Rescue Zone) System — Do you have CAT cabling and PoE devices? Backup power?
  • Mass Notification — Does the system transmit touch tones for touch tone activation?
  • Loud ringtones — Ringer voltage may not trigger ringtones.
  • Ring-Activate Devices — Incoming ring voltage detection.
  • Battery backup — Should be considered for routers etc. (minimum four hours for all VoIP devices).

Let’s look at other important technical areas of paging systems. Suppose a customer’s speakers aren’t loud enough, what could be causing the problem? Take a look at the desired power of the speakers by checking something like the Table of decibels lost (dB). Keep in mind that the sound dB scale is logarithmic and the bottom quantity doubles or halves each 10 dB.

After you have an concept of ​​the sound degree to anticipate, test the Viking Product Assist Net Web page for the Paging Power Table (895) within the utility notes. The technician rapidly discovers from the chart that the wire gauge is just not appropriate for the anticipated dB degree of the audio system. He might rewire the system or just add a extra highly effective amplifier or energy provide.

It is fairly easy when you perceive. I extremely suggest that you simply try the intensive Vikings YouTube Channel. It is an important instructional useful resource and I would not anticipate something much less from a devoted firm like Viking. Additionally, remember their wonderful tech assist line.
