Stealth Laboratories SD-150 Economical Siren DriverThe SD-150 provides a high volume output (120dB at 10 ft.) with low current draw of 1.5 Amps (800 mA in reduced draw setting). Two outputs are provided, steady and yelp with a combination trigger option for controls that have a single alarm output with a pulsing option for fire or burglary. When pulsed, this channel produces a distinctive third sound pattern. |
Stealth Laboratories SD-2000 Neighbor Friendly Siren DriverThe SD-2000 provides an effective answer to annoying false alarms. Two outputs are provided, one instant for indoor speakers and one delayed for outdoor speakers. In the event of an accidental alarm caused by the user, the indoor speakers are activated immediately. Outdoor speakers sound only after a pre-programmed delay, allowing time for the home-owner to disarm the system and avoid disturbing his neighbors. |
