The Select-Alert Siren and Strobes are a highly effective additional signalling device to alert to any unauthorised use and tampering of important devices when used in conjunction with a triggering device. The combination of alarm and super bright flashing LEDs offers excellent protection for an array of circumstances as they draw attention in a hurry. The sirens and strobes will work in conjunction with push buttons, protective covers, as well as many other products. *For STI-SA5600 European installation KIT-71101A-W is required. Currently only suitable for surface mount applications. To view other sirens and strobes, please click here.
