Sounder and Visual Alarm Device

The PPMS Sound and Light Sounder  is a combined unit that forms part of the PPMS (Plan Particulier de Mise en Sécurité, or school lockdown safety plan) confinement system.

It is designed to respond to major risks, within the Vigipirate plan at the "terrorist attack alert" level. It meets the safety measures put in place by the French Ministry of National Education for schools and educational establishments.

The confinement system triggers a specific "lockdown alarm" alert.

It is used to warn the occupants of a building of the presence of a terrorist attack risk. It emits the attack alert sound together with the visual alert. It is particularly suitable for noisy premises or those occupied by deaf or hard-of-hearing people. The sounders must be audible from every point of the building in which they are installed.

** It emits the Afnor NF S32-001 sound or the PPMS alarm sound and produces a white or blue flash.
