ALERT warns and informs occupants

Equipped with configurable indicator lights and an audible alarm, ALERT is a versatile device for a wide range of situations.

An alert has been triggered and you’d like to be notified?

ALERT integrates a wireless communication module and informs you remotely.

ALERT can also be used to signal a new event to a group of people using instant visual and/or audio notifications (such as meeting room availability, air quality indicator, intruder alert, etc.).

Reinforces the fire safety system

A fire can spread in less than 5 minutes, and carbon monoxide is completely odorless.

Every second counts to alert occupants in the event of danger.

Connected CO alarm / Détecteur de CO connecté

Interconnected with detectors

When a smoke detector* triggers an alarm, ALERT reacts instantly, activating both a light signal and an audible alert. The device effectively warns even the most vulnerable occupants, such as the deaf and hard-of-hearing, or people with reduced mobility.

Vibrating cushion compatible

The VIBRATE vibrating cushion (optional) is placed under the pillow to wake the resident if the ALERT light and sound alerts are not heard.
