Connection Choices for the Power Outage Alert System

What Is the Power Outage Alert System?

The Power Outage Alert System is an add-on compatible with all EverSafe battery-powered backup generator models.

In the event of a power outage, the alert system will automatically call up to four pre-set phone numbers when either:

  • The backup generator loses incoming utility power.
  • The generator ceases to supply power (i.e., batteries are drained).

It can also:

  • Report the ambient room temperature when the alert is triggered.
  • Allow custom alert messages—useful especially for facilities that have units in different locations.

How the Alert System Handles Calls

To send or receive calls, this system must be linked via its phone jack to a phone line or network. You generally have three connection methods:

  1. Standard Analog Phone Line (POTS) – Regular landline.
  2. Voice-over IP (VoIP) Adapter – Via wired or Wi-Fi internet networks.
  3. Wireless Cellular Adapter (Mobile Hotspot) – Using cellular network service.

How well each works depends on:

  • Your facility’s existing phone/internet infrastructure.
  • IT/technical capability.
  • Whether phone or internet services remain reliable during an outage.

1. Using a Standard Phone Line

Also called a “copper line” or POTS (Plain Old Telephone Service), this is the default and most reliable choice. In emergencies, traditional landlines often continue to work because they’re powered independently of your main electrical supply.

Setup is simple: plug one end of the phone cord into the alert system, and the other into the wall jack. No additional adapters are required.

2. Using VoIP

If your location uses modern telecom systems without traditional phone wiring, VoIP may be used. However, since the alert system expects an analog interface, a VoIP adapter is needed to convert digital/internet signals into analog ones.

Two common setups:

  • Wired VoIP: The adapter plugs into an Ethernet port; the alert system connects via a phone cable to that adapter.
  • Wireless VoIP: Adapter connects to your Wi-Fi; the alert system still uses a phone cable to the adapter.

Caveats: VoIP depends on internet connectivity and power. If the internet or power fails, VoIP may also fail, making it less reliable than analog in some emergency scenarios.

3. Using a Cellular Hotspot

This option uses wireless cell-network service via a mobile hotspot. You connect the alert system to the hotspot using a phone cable, and the hotspot provides the cellular network connection.

Pros:

  • Cellular networks often maintain service during power outages (cell towers tend to have backup power).
  • It can serve as a fallback for locations without reliable landlines or internet.

Cons:

  • The hotspot needs its own power—many users draw that from the EverSafe backup generator.
  • Signal strength may vary (especially in rural or remote areas), which could affect performance.
  • Requires a SIM card and active service plan from a carrier (note: EverSafe does not supply the carrier plan).
