Warning Sirens

KPE siren

The S+ and S- terminals of the NZ34 or NZ34-DIN power supply can be connected to a 12 V siren that begins hooting intermittently after reaching stage I, and continuously after reaching stage II.

The indoor KPE siren is suitable for places without constant service. Its volume can be compared to a car alarm. Its task is to alert and summon personnel from another room.

JTO siren

The weaker JTO siren is suitable for areas with permanent human presence, such as gatehouse, reception, etc. Its volume can be compared to an electric alarm clock.
