Bogen – Special Electronic Systems

Ambient Noise Sensor (ANS501)

• Automatically adjusts paging level as ambient noise levels rise and fall
• Supports up to 4 small sensor microphones (1 ANS500M included) for large areas
• Sensor microphones can be located up to 2,000 feet from control unit
• Easily connects in at pre-amp out -power amp in process loop
• Input/output: 600-ohm balanced, unbalanced

Voice-Activated Relay (VAR1)

• 2 sets of C-Form (N.O. & N.C.) relay contacts respond to audio activity
• 4 levels of input signals: microphone, 600-ohm line, 25V, & 70V speaker systems
• Built-in balanced, low noise, high gain microphone pre-amp
• A transformer-isolated, 600-ohm small signal level output of detected audio available
• Trigger threshold adjustment

Tone Generator (TG4C)

• 4 types of tones: steady, pulsed alarm, slow whoop, and chime
• Tones triggered by external contact closure (momentary or long duration)
• Choice of continuous generation of tones or two-burst operation (except for steady tone)
• External audio signal can pass through TG4C and is suppressed during tone generation
• Adjustable tone level and pitch
• 600-ohm output

Night Ringer (NR100)

• Responds to 90V ring signals or external contact closures
• Produces dual-frequency electronic ringer tone
• Easily connects to any paging system
• Automatically mutes background music while ringing
• Ringer volume control
• Compact size
• Low current draw

Talkback Amplifier (TBA15)

• Hands-free 2-way conversations through the paging system
• 15W of speaker power
• Works on 25V and 70V speaker systems
• Adjustable switching sensitivity control for switching from listen to talk
• Talk Back and page volume controls
• Mute input forces amplifier into page mode

Door Phone (ADP1)

• Suitable for indoor or outdoor station, door, or gate communications
• Secure entry access to commercial, industrial, or residential locations
• Pushbutton initiates the call at remote locations
• Adjustable microphone and speaker volumes
• Adjustable call timeout (15 seconds to 2 minutes)

Attenuators (AT10A, AT35A)

• Adjusts loudspeaker output levels on 25V and 70V systems
• 2 models control up to 10-watt or 35-watt speaker systems
• 10 attenuation steps and an off setting
• Automatically mutes background music while ringing
• Mounts in standard electrical box
• Simple connections

Attenuators (ATP10, ATP35)

• Bypass feature allows emergency announcements to be heard at highest level even if local speaker volume is set low or off
• Adjusts loudspeaker output levels on 25V and 70V systems
• 2 models control up to 10-watt or 35-watt speaker systems
• 10 attenuation steps and an off setting
• Mounts in standard electrical box

Line-Matching Transformer (WMT1A)

• Hi-Z, 10k-ohm primary impedance
• Lo-Z, 600-ohm secondary impedance, balanced with center tap
• Matches high-to-low impedance or low-to-high impedance
• Adapts line level signals to microphone inputs
• RCA connector for Hi-Z side
• Screw terminals for Lo-Z side
