VOIP

Voice Over Internet Protocol is becoming more and more popular, primarily because it is usually cheaper than traditional phone service (POTS). If you have an alarm system, there is a chance that your alarm panel can not communicate over VOIP, this is particularly true if you have a third party VOIP provider like Vonage. If you receive your VOIP service directly from the cable company or phone company (Not over DSL), there is a good chance that it will work.

You should, however, be aware that a power outage will stop your modem from working, and the alarm panel can not dial out. The alarm system has a back up battery. At the very least, you should have a UPS (back up battery) that the modem is plugged into. This will work for short periods but not for long outages.

If you switch to VOIP, you should contact your alarm company in advance so they can best direct you how to test your system and determine if any phone wiring is required.

Once VOIP is active, you should test your system with the central station and then test your system regularly.

Carbon Monoxide and Smoke Detector Life Span

CARBON MONOXIDE DETECTORS
The life expectancy of a carbon monoxide detector which is part of a security system is approximately 5 to 6 years. After this period of time, if carbon monoxide is present, there is a good chance that the unit will not be able to detect the gas.

Depending on the brand, notification of sensor failure is different. Some units have the expiration date written on a label under the cover. Other units have a combination of visual notification and chirping.

It is not a bad idea to be proactive and if your units are 5 years old, have the sensors replaced.

SMOKE DETECTORS
Smoke detectors have a life expectancy of 10 – 15 years and when they fail, have a tendency to false alarm. Commercial fire alarm systems are required to have their systems inspected at least once a year by a licensed contractor in accordance with NFPA standards. No such requirement exists for residential fire alarms, but it is highly recommended that these systems be checked for proper operation as well.
