Solar Siren Panel for Outdoor Alarm System
Extend a compatible alarm system with an outdoor solar siren panel. A 110 dB audible alarm and blue flashing light help make a triggered event noticeable at the property.
✅ Add an outdoor warning point - The siren carries the alarm response beyond the indoor control panel.
✅ Make the alert visible - A blue flashing light gives a visual signal alongside the sound.
✅ Set the output for the location - Four volume settings, including mute, let you adjust the audible response.
✅ Keep backup power available - The rechargeable battery supports operation when solar power is unavailable.
An Outdoor Extension for Selected Alarm Systems
The KR-SJ1 is intended for compatible W181, W184 and W204 alarm systems. Wired and wireless linkage options help you plan the connection around the installation.
Solar charging and AC/DC support provide power options for the siren location. Water-resistant and anti-tamper functions suit its outdoor role, while memory protection helps retain the configured information.
