Great product, with good pricing and very prompt shipping.
Just install them they look good!!!
This is a great product at a great value.
The product is fine and your price is less than half of that of others.
VERY HAPPY, IN FACT ORDERED SEVERAL MORE
I needed to replace the smoke in my RV and this the type of detector that was in it. At the time I was looking for detectors I found you had this 6 pack and I thought I should replace the detectors in my home. They are working great and easy to install.
I am very pleased with the efficiency and ease with the handling of my return of the smoke detectors. I was able to order the correct ones with one phone call.
So far so good
Great Value much better than retailers
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 this 6-pack and I am now secure and safe again. A wonderful product!! And since most permit inspections require one in each bedroom, this is a fantastic way to satisfy that requirement.
Product FAQs
The smoke alarm chirps to indicate a "low battery" condition, meaning the battery needs to be replaced. Battery powered smoke alarms will chirp a minimum of 30 days before the battery completely loses power.
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.
The flashing red light gives a visual indication that the smoke detector is functioning properly. It also indicates a working battery is connected to the smoke alarm.
When a green light is present on your smoke detector, it means that AC power is currently operating the alarm.
If the green light on your smoke detector is not on, it means the AC power has been interrupted to the alarm. Check the circuit breaker and AC wiring to make sure power is still reaching the smoke alarm.
When interconnected alarms are alarming, the smoke alarm which initiated the alarm, either by test button or sensing smoke, will flash the red LED light approximately once per second. The red LED light on the other non-initiated interconnected smoke detectors will not be lit but will sound the alarm.
The NFPA 72 standard states the interconnect limit is 12 smoke alarms and up to 6 other alarms (heat alarms or carbon monoxide detectors) for a total of 18 total alarms. With 18 alarms interconnected, up to an additional 6 relay modules may be interconnected (for a maximum of 24 devices).
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.
