Model DG-12II is a 12 zone alarming sound activated audio monitoring base station. When combined with companion unit DG-MA (Listen/Talkback Amplifier) and interfaced with remote speaker/microphones, it provides a sound activated duress audio system with two-way communications. Each zone has a variable threshold level control, based on frequency and sound pressure level, and a variable alarm delay (from 0.1 to 3.2 seconds) that can be set by using the built-in tester(included) for alarm audio and time delay. The time delay feature is effective in reducing false alarms. The DG-12II is supplied with 12 zone cards. When a sound or disturbance occurs that is below the preset threshold level, the nearest microphone detects the sound and identifies the zone with a lighted LED that blinks GREEN. If the sound increases, the LED intensifies to a solid GREEN. If it exceeds the preset threshold, the zone goes into alarm, with the zone LED changing to RED, along with a 3 second beep. A relay contact closes to activate a camera or other annunciation. The person at the remote station can communicate hands-free with personnel at the base station. The person at the DG-12II can talk/listen with the remote station by pressing the zone switch. Talkback to the remote station is with a hand-held microphone (provided) that is connected to the companion DG-MA Listen/Talkback Amplifier. Zone alarm can be cancelled by automatic or manual reset feature. Automatic re-set can run between 3 sec and 3 minutes. All LOUROE Microphones (A, B, C, D, D-V, E, K and L-DT) and all Speaker/Microphones (Models TLI, TLM, TLMC, TLO, TLSP and TLSP-PB) are compatible with the DG-12II.
