Review on SD 15W ULF 15 Watt Alarm Siren by Darin Schaffer

Revainrating 5 out of 5

Loud and variable - horns & sirens

Very good alarm clock. Depending on which cable you connect and what voltage is applied, how the sound changes. One produces a constant tone and the other an intermittent tone. The applied voltage changes the frequency. A very nice and very loud alarm clock. Multifunctionality is a great feature.

Pros
  • Product type: Siren
Cons
  • Weight

Works fine with my DSC2400 Panel. Took some time to get because it was back ordered.

Inexpensive and as loud as the others I have tried with my Vista 20P alarm.
