Customer Reviews For The USI Compact Size Battery-Operated Ionization Smoke Alarm (SS-770-24CC)
Replaced my old unit after 10 years. Easy to install.
The smoke detector has worked well for the last 10 years and I expect the same from this replacement.
Met my expectations arrived as told was on backordered but that's ok.
I discovered a smoke detector that was too old. Lots of my other ones were also. Even though they still tested good, they may not have worked in a fire situation. The test buttons only test the alarm, not the sensor. So I ordered a 6-pack and now two more singles. I am now secure and safe again with all new detectors. A wonderful product!! And since most permit inspections require one in each bedroom, this is a fantastic way to satisfy that requirement and make you safe and secure.

Exact replacement I needed.
AC powered smoke alarms with battery backup will chirp indefinitely assuming AC power is present; if battery power is low, or battery is removed; until a fresh battery is installed. Approved replacement batteries are listed on the back of each smoke alarm and in the user's manual.
Certain model smoke alarms with a silence button (designed to silence the alarm during a nuisance alarm) may chirp to indicate the smoke alarm is in the silence mode. The chirp will stop after approximately 8 minutes and the smoke alarm will return to its normal operation.
If battery backup alarms and non-battery backup alarms and accessories are mixed in an interconnect system, all devices without battery backup WILL NOT operate during an AC power failure.
CAUTION: USI alarms and accessories should only be interconnected with other USI alarms and accessories. Connecting devices from another manufacturer to USI devices may result in nuisance alarms, failure to alarm, or damage to one or all of the devices in the interconnect system. All interconnected USI alarms should be powered by the same fuse or circuit breaker. Smoke alarms shall not receive their power from a circuit that is protected by a ground fault circuit interrupter. Improper connection will result in damage to the alarm, failure to operate, or a shock hazard.
