Interconnectivity Without the Wires
Until now, alarms that could signal each other were only available in homes with hardwired systems. All ONELINK alarms, however, communicate with each other wirelessly through integrated radio frequency. This means that when one sounds, they all sound, providing a whole-home safety network.

This two-pack of ONELINK alarms helps you create a new system or expand an existing 120-volt AC system of up to 18 alarms. Just replace one or two of the alarms with a ONELINK Wireless Smoke Alarm, and your alarms will continue to be able to communicate with one another.

Accurate Technology Minimizes False Alarms
Utilizing environmentally friendly photoelectric technology to sense smoke, ONELINK Wireless Smoke Alarms provide optimal protection against smoldering fires. This technology also reduces the chance of false alarms caused by cooking or bathing.

Designed for Safety and Ease of Use
As user-friendly as they are effective, each ONELINK Wireless Smoke Alarm has a dual-purpose button that silences the alarm and tests the system's function. And because the alarms each emit a loud 85-dB siren, you'll be sure to hear them, even if you're asleep or in the shower. The audible low-battery signal can be muted for up to eight hours (so as not to disturb your sleep).

Additionally, each alarm has an easy-access battery door that allows for quick changes without necessitating that you remove the alarm from the ceiling. An optional theft-protection lock prevents unauthorized removal of the batteries or unit.

As safe as they are easy to use, these ONELINK smoke alarms are FCC compliant for wireless device standards, and they meet UL217 standards for wireless smoke alarm systems.

Each ONELINK Wireless Smoke Alarm is backed by a 10-year limited warranty.

What's in the Box
Two Wireless Smoke Alarms; four 'AA' batteries; instructional DVD; and manual.

The First Alert ONELINK provides more features and better protection than standard alarms.

First Alert SA501CN2 ONELINK Wireless Battery Operated Smoke Alarm, 2-Pack Review

Limited range, but works as advertised - H.M.M. - Hershey, PA USA
Purchased two smoke/carbon monoxide detectors and two smoke-only detectors for different areas of the house. Units function as advertised but found to have what I consider to be very limited range.

Setup was simple, and everything worked perfectly during short range tests. However, when units were placed 25' apart with a single wood stud/drywall wall between them they wouldn't communicate. Tried to relocate slightly in case I was getting interference from wiring in the wall, but no luck. Also tried different units in different positions/orientations in case transmission was direction or there were variations in signal strength between units. No luck.

FirstAlert customer service was friendly but had no real solution other than to reorient or reposition the detectors. They said the expected range is about 30'. Not for me.

Overall I'd say they're good products with good features (haven't had them long enough to comment on battery life). However, the limited range limits placement options and/or requires a relatively dense network of detectors.

PS: Smoke-only and smoke/carbon monoxide detectors WILL work together in a network. However, the smoke-only detectors don't have ability to "say" carbon monoxide. If a carbon-monoxide detector is triggered and relays an alert to a smoke-only alarm, the smoke-only alarms only has the ability to say (for example) "evacuate... smoke in bedroom!"
