The new products address evolving market developments for close integration of
voice alarms with fire protection systems. Experience has shown that in the case of
a fire or another dangerous situation, a simple alarm tone is often not observed but
instead misinterpreted as a false alarm or as a drill. As a result, the persons who
need to be warned either don’t react or react belatedly. Speech-based alarms keep
evacuation times as short as possible and minimize the risk to people.
The sounders feature 16 integrated tone patterns and three different sound levels
(Min/Mid/Max), with the highest sound pressure being 99 dBA. The voice sounders
have the same features as the sounders, but in addition contain messages that can
be emitted in two languages along with an attention tone. In total, 15 languages are
available in five pre-defined message categories: fire evacuation, emergency
evacuation, alert, test and all-clear. The tone and voice messages are compliant
with EN 54-3 and synchronized in an audible area and across all loops of a panel.
Voice messaging, especially if it is in two languages, improves the reaction time,
particularly for people who are not familiar with the building. Beyond the standard offering, the portfolio includes customized devices where any languages, message
categories and tones can be incorporated.
The optical alarm devices feature three beacon settings in accordance with EN 54-
23, which can be tailored to different room sizes and detector coverage areas. They
have an extra setting that supports the use of the device with supplementary optical
indication to save power. In addition, they are designed for use in system extensions
and modernizations. All devices are addressable, loop-powered, and available with
red and white LEDs.
To improve evacuation performance, a shorter pulse length with higher illumination
is built into the beacons because studies have shown that this combination
increases awareness in the case of an alarm. Beacons with these features are
especially valuable in areas with loud ambient noises where acoustic signals are
easy to miss. In addition, they help reach people who are hearing-impaired, wearing
ear protection or using headphones.
