Medical alert systems give seniors a way to summon help immediately through a pendant, wristband or a small unit clipped to a belt. If a senior has fallen or is experiencing a health crisis, pushing an emergency alert button sends an immediate signal to an operator who can summon help. Originally, all medical alert systems consisted of a base attached to a phone line and a portable alert button. However, newer technology has added various convenient features, such as two-way communication through portable devices, the use of cellular networks to enable mobility and GPS location tracking. The latter two improvements free active seniors from their homes while allowing them to stay connected to emergency services.

Why Use a Medical Alert System?

One in five falls among senior citizens can lead to serious injuries, and the more quickly help arrives, the better the outcome for seniors experiencing medical emergencies. Many older adults are committed to aging in place, staying in their homes and arranging for home assistance and support as needed. Technology can help with this, and the ability to immediately call for help is one advance that medical alert services have provided for older people living independently.

Numactive Emergency Alert Systems

Numactive offers two different systems, Alert Home and Alert Sky, to suit the unique needs of each user. Each option involves user activation and the opportunity to speak with a call center professional. Both levels of monitoring include an alert pendant, and the Alert Home service also includes a base unit. Testing out the system by making a call during setup gives seniors confidence in the emergency alert process while ensuring that the unit is working properly.

Below are the notable differences between Alert Home and Alert Sky.

Alert Home

For seniors with limited mobility, the Alert Home system provides monitoring in a house or apartment through a landline, so a traditional phone or cable phone service is required for setup. The signal range is 500 feet from the base, the usual range for a cordless phone, providing coverage from the yard, driveway and most rooms in the house.

Seniors can wear the alert as a pendant or wristband. In an emergency, a user simply presses a large button on the portable unit to summon help. Within 6 feet of the base, they can communicate by voice with the operator. If direct communication isn’t possible, the emergency contact on file will be called, and if the contact person is not available, operators are trained to call emergency services.

Alert Sky

With the Alert Sky system, the pendant is a portable unit capable of two-way communication, enabling the wearer to contact a friendly operator who can answer questions and call a contact person or emergency service on their behalf. Mobile sensors in the unit detect falls, instantly triggering two-way communication, and GPS data makes it easier to locate a senior when there’s an accident or emergency. Alert Sky operates using mobile phone networks, so it functions anywhere cell phone service is available, allowing complete mobility paired with the security of wearing a monitoring device.

The pendant for the Alert Sky system comes with a charger base and can be worn around the neck on a lanyard or clipped to a belt. The portable unit holds a charge for 72 hours, and a text alert is automatically sent when only two hours of operation remain. Numactive recommends that users keep the charger next to the bed and within reach so the unit remains available while being recharged each night. The Alert Sky system gives seniors more independence by providing service wherever cellular networks are available, including all of Canada and the United States, and during travel between the two countries.

Medical Alert and Monitoring Costs

The monitoring cost is $34.99 per month for the Alert Home system and $49.99 per month for the Alert Sky system. This cost is discounted when the service is paid for in advance. Monthly, quarterly and annual membership plans are available, with the annual plan offering the most savings. For seniors who may not be able to afford any of these options, financial assistance may be available through Medicaid and other programs, such as veterans’ assistance funds. Numactive systems include the monitoring equipment at no additional charge, and the hardware is returned when the service stops.

The course includes training in all types of emergencies, including medical, fire, automotive and flooding. Seniors who use the Numactive alert system are encouraged by company representatives to call for any type of emergency, not just falls and medical issues.
