SPL-5020 R

Outdoor siren with optical and acoustical signaling

SPL-5020 R is an optical-acoustic siren designed for outdoor installation, provided with a powerful 5 W / 12 V incandescent lamp and a piezoelectric transducer. It offers three types of 120 dB intensity modulated tones to choose from. This model is designed to work with a 0.8 Ah, 6 V gel lead-acid battery, which is installed inside the enclosure and serves as a backup power supply. Enclosure of the siren is made of polycarbonate, which ensures high mechanical strength and aesthetic appearance of the device that remains unchanged over time. The device is provided with tamper protection against opening or tearing off the wall. The SPL-5020 R model can be additionally provided with the SPL-TO sensor for protection against damping the siren by covering the piezoelectric transducer with PUR foam. Optionally, an inner shield of galvanized sheet is available for protection of the electronics board and transducer against mechanical damage. The electronic circuits are properly weatherproofed, so they are also resistant to the effects of harsh environmental conditions.

The SPL-5010 optical-acoustic siren is available in three color versions: SPL-5020 R (red), SPL-5020 BL (blue) and SPL-5020 O (orange).
