Heads-Up and Emergency Alarms
Ales
When Nest Protect has something to say, it will speak
to you and light up instead of just beeping. Nest
Protect has two kinds of voice ale: Heads-Up and
Emergency Alarm.
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, tell you what room the emergency is in and sound
a loud alarm. If there’s both smoke and CO present, the
smoke alarm will take priority.
Silencing
Heads-Up ales and Emergency Alarms can be silenced
by using the Nest app or pressing the buon. 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 baeries. This will disable
the alarm so that it cannot sense smoke or carbon
monoxide, leaving you at risk.
Because there are many dierent types of re, 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 had to sound the Emergency Alarm.
Have more than one Nest Protect?
Aer 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.
