SPW-250 R - indoor acoustic signaling device with emergency power supply
SPW-250 R is a wired acoustic signaling device for indoor installation, equipped with a piezo transducer. The device offers modulated sound signaling of 120 dB, powered from the control panel with an additional backup battery.
- Acoustic signaling provided by a piezoelectric transducer
- Three types of modulated sound signaling
- Sound intensity of 120 dB
- Emergency power supply from CR123A 3 V lithium battery
- Anti-tampering protection against detachment from the ground and opening of the housing
Application and characteristics of the SPW-250 R alarm device
SPW-250 R is a wired, indoor acoustic signaling device designed for burglary and assault alarm systems. Thanks to the use of a piezoelectric transducer, the device generates a loud, modulated acoustic signal.
The sound intensity of 120 dB ensures very good audibility in large spaces, such as warehouse and production halls or parking lots inside buildings. The siren is powered from the control panel, with an internal lithium battery acting as a backup power source.
Safety, reliability and design
The housing of the SPW-250 R siren is made of polycarbonate, which ensures high mechanical strength and a durable, aesthetic appearance for a long time expLoatation. The device is equipped with tamper-proof protection against opening the housing and detaching the alarm device from the wall.
In addition, the siren will automatically trigger an alarm if the connection to the control panel is broken or the external power supply fails. The use of emergency power supply from a lithium battery and tamper protection increase the security level of the entire alarm system.
