SMOKE DETECTION
Are more smoke alarms desirable?
The required number of smoke alarms might
not provide reliable early warning protection
for those areas separated by a door from the
areas protected by the required smoke alarms.
For this reason, the use of additional smoke
alarms for those areas is recommended for
increased protection. The additional areas
include the dining room and hallways not
protected by the required smoke alarms.
The installation of smoke alarms in kitchens,
attics (finished or unfinished), or garages is
not normally recommended, because these
locations occasionally experience conditions
that can result in improper operation. As Nest
Protect is also a carbon monoxide alarm, it is
not recommended to install it in a furnace room
or a utility room if it contains a water heater or
a boiler. It should be 5 – 6 m (15 – 20 ft) from
these appliances to avoid transient conditions
and/or perceived nuisance alarms.
AC INSTALLATION WARNINGS
ELECTRICAL SHOCK HAZARD
• Turn off power to the area where you will install
this unit at the circuit breaker or fuse box
before beginning installation. Failure to turn
off the power before installation may result in
serious electrical shock, injury or death.
• Do not restore power until all alarms are
completely installed. Restoring power before
installation is complete may result in serious
electrical shock, injury or death.
• Turn off the power to the area where the
alarm is installed before removing it from
the mounting bracket. Failure to turn off the
power first may result in serious electrical
shock, injury or death.
• If any unit in the series does not alarm,
TURN OFF POWER and recheck connections.
If it does not alarm when you restore power,
replace it immediately.
• Attempting to disconnect the power
connector from the unit when the power is on
may result in electrical shock, serious injury
or death.
• Failure to meet any of the above requirements
could damage the units and cause them to
malfunction, removing your protection.
• Improper wiring of the power connector or
the wiring leading to the power connector will
cause damage to the alarm and may lead to a
non-functioning alarm.
• This unit must be powered by a 24-hour,
230V AC pure sine wave, 50Hz circuit. Be
sure the circuit cannot be turned off by
a switch, dimmer, or ground fault circuit
interrupter. Failure to connect this unit to a
24-hour circuit may prevent it from providing
constant protection.
