Hi Ken,
In reference to Kevin Bucklands comment.....
"Not all VoIP providers are the same so it informs them of the need to have a back up battery for their VoIP equipment to ensure that the phone continues to function and also tells them that changes made by their internet provider may cause their alarm to stop communicating reliably and that this is beyond our control"
Please don't tell your clients that they have to have a battery backup to keep their communication path open. This is a myth...!! The signal has to get to the house by a transmission line. The signal also has to be amplified or repeated along the way. This usually takes place on the pole in a box that might or might not have battery back up. If the power in the area goes out; the power to the amplifiers or repeaters will also go out. In this area, if we loose power......we loose voip before it gets to the house...!

With regard to dropping the negative reference to VOIP over POTS I don't think we should as long as we have no control over FACILITIES BASED vs NON FACILITIES BASED services which the customer may contract with. The customer may start with cablevision and then after everything is running well decide to cut costs by going to MAGIC JACK for $1.79/Month. We only find out after an unreported entry.....
If a customer uses FACILITIES BASED VOIP we will install a 350VA UPS on the MODEM for standby power as well as a GSM, IP or other form of BACKUP power for the voip equipment.
A lot of facility managers that want you to use their IP network for communications have no idea that their IT department frequently takes the network down for administrative management. During this down time there is NO PATH..........(((That is why we insist on a back up to any path for BURG as well as FIRE.))))
A lot of installers do not know the difference between VONAGE, MAGIC JACK etc vs CAGBLEVISION or COMCAST.........
Time for the Dr. to tell the patient what he needs. Let the patient refuse if he wishes but make it an informed refusal.

To all
For your records and general knowledge, I've attached a letter from NJ's DCA. NJ is accepting VIOP for fire alarm systems. It's a hard pill to swallow and if you read the letter closely, it's up to the AHJ. Also in the information that the, so called, approved provider's state, they mention the ability to operate with a home security system, but commercial fire systems are not mentioned at all. I have no idea how they're getting away with it.
