Smoke Alarm - Kidde KN-COSM-I Guia Del Usuario

Features and General Information
• Seven (7) years after initial power up, this unit will "chirp"
every 30 seconds. This is an "operational end of life" feature
which will indicate that it is time to replace the alarm.

Smoke Alarm

The smoke alarm monitors the air for products of combustion
that are produced when something is burning or smoldering.
When smoke particles in the smoke sensor reach a specified
concentration, the alarm/voice message warning system will
sound, and be accompanied by the flashing red LED light. The
smoke alarm takes precedence when both smoke and carbon
monoxide are present.
WARNING: PLEASE READ CAREFULLY AND
THOROUGHLY
NFPA 72 states: Life safety from fire in residential occupancies is
based primarily on early notification to occupants of the need
to escape, followed by the appropriate egress actions by those
occupants. Fire warning systems for dwelling units are capable
of protecting about half of the occupants in potentially fatal
fires. Victims are often intimate with the fire, too old or young,
or physically or mentally impaired such that they cannot escape
even when warned early enough that escape should be possi-
ble. For these people, other strategies such as protection-in-
place or assisted escape or rescue are necessary.
• Smoke alarms are devices that can provide early warning of
possible fires at a reasonable cost; however, alarms have sens-
ing limitations. Ionization sensing alarms may detect invisible
fire particles (associated with fast flaming fires) sooner than
photoelectric alarms. Photoelectric sensing alarms may detect
visible fire particles (associated with slow smoldering fires)
sooner than ionization alarms. Home fires develop in different
ways and are often unpredictable. For maximum protection,
Kidde recommends that both Ionization and Photoelectric
alarms be installed.
• A battery powered alarm must have a battery of the specified
type, in good condition and installed properly.
