Heads-Up and Emergency Alarms
Silencing
Heads-Up ales and some Emergency Alarms can be
hushed by using the Nest app or pressing the buon.
In some cases, the smoke level may be too high for the
Emergency Alarm to be hushed. Only silence an alarm
once you have checked conditions at the Nest Protect
that rst sounded the alarm. Do not silence Nest
Protect by disconnecting it from mains voltage and
removing the baeries. This will disable the alarm so
it cannot sense smoke or carbon monoxide, leaving
you at risk.
Because there are many dierent types of res, you may
experience an Emergency Alarm without having rst
experienced a Heads-Up ale. This means that critical
levels of smoke or CO occurred extremely quickly
and Nest Protect has to sound the Emergency Alarm.
Have more than one Nest Protect?
Aer all the Nest Protects in your home are connected
to each other, if there’s a Heads-Up or an Emergency
Alarm in one room, they’ll all tell you what the danger
is and which room it’s in.
If multiple Nest Protects are interconnected, a Heads-Up
ale or Emergency Alarm can be silenced only at the
Nest Protect that originally sounded the ale. You’ll need
to go to that room to silence all the Nest Protects in your
home. Always check the conditions near the Nest Protect
that rst detected the smoke or carbon monoxide before
silencing it.
Ales
When Nest Protect has something to say, it will speak
to you in words and light up instead of just beeping.
Nest Protect has two kinds of voice ales: Heads-Up
and Emergency Alarms.
When smoke or carbon monoxide levels are heightened
but haven’t yet reached Emergency Alarm levels, Nest
Protect can sound a Heads-Up as an early warning.
Nest Protect will pulse yellow and tell you where there’s
smoke or carbon monoxide.
You’ll get an Emergency Alarm when smoke or carbon
monoxide reach critical levels. Nest Protect will pulse
red, sound a loud alarm, and tell you what room the
emergency is in. If there’s both smoke and CO present,
the smoke alarm will take priority.
