8 | UNDERSTANDING YOUR HALO
Halo uses different visual and audible alerts to let you know what is happening inside your home. These alerts
are in addition to the standard alarm sound, which is triggered by a smoke or carbon monoxide event. Halo will
provide audible, verbal alerts, and visual information in the form of colored lights.
8.1 | ALERTS
Halo has two different kinds of voice alerts - Pre-Alerts and Emergency Alarms.
Pre-Alert Notifications:
When smoke levels have increased but have not reached an emergency alarm level,
Halo will announce a caution alert as an early warning. Halo will pulse an amber light and tell you the location of
the alert. You will receive a push notification on your phone when this occurs.
Emergency Alarms:
Once the smoke or carbon monoxide has reached critical levels, Halo will begin pulsing
red, and begin a specific horn pattern based on the detected emergency. Halo will also announce in the room in
which the emergency has been detected. If both smoke and carbon monoxide are present, the smoke alarm will
take priority.
8.2 | HUSHING
Pre-Alerts and Emergency Alarms can be hushed (silenced) by using the Halo app or pressing the center Halo
button. In some cases, the smoke or CO level may be too high for the Emergency Alarm to be hushed. Only
silence the alarm when you have checked the conditions surrounding your Halo. Halo will flash white and
announce it has been silenced when hushed properly. Do not silence Halo by disconnecting it from the Halo
power connector and/or removing its battery. This will result in the alarm being unable to detect smoke or
carbon monoxide, leaving your home at risk.
8.3 | INTERCONNECT FEATURE
Your Halo Smoke and Carbon Monoxide Alarm can interconnect with other multiple-station Halo alarms. This
means that when one Halo raises either a smoke or CO critical level alert, every Halo inside the house will
tell you in which room the alert originates. For example, if there is smoke inside the living room, all Halos will
announce smoke has been detected in the living room. To silence the alert, go to the room where the alarm was
triggered. All of the Halos in the house can be hushed through the alarming Halo. Press the center button on
the Halo or use the Halo app to hush the alarm.
Note: Halo is only approved to interconnect with other Halo products. It is NOT approved to interconnect with
any smoke alarms that are not Halo products. If only one Halo is installed in a home, the Halo will only go off
when there is an emergency inside the room in which it is installed.
