Description

The sirens are designed for continuous round-the-clock operation (broadcasting on command pre-recorded speech information about actions aimed at providing safety) in fire alarm and fire extinguishing systems in conjunction with the reception and control devices. They are used in hazardous areas of 1-2 classes. The siren is triggered by supply voltage or external control signals. The selected speech message or sound signal is broadcast continuously until the siren is de-energised or the control signal is removed. Speech messages are recorded at the manufacturer's plant by the customer's order. Set of sirens: speech unit; one or two (optional) horn explosion-proof loudspeakers GRV-25A with cables for connection to the speech unit; network adapter (optional).
