SC-100 Basic 2-Way Window/Partition Intercom System

SC-100 Rear View

The Basic Voice Communication System for

High-Security and Isolation Booth Situations

Today's security and isolation booths and ticket booths are often the best step you can take to protect your employees. But do they protect and also help maintain your very important good will? Not if clerks and customers have to shout and growl and repeat themselves to be heard or understood.

The Alpha Communications┬« / Haven SC-100 unit is a 2-way, hands-free audio system that provides high-quality personal communication between people separated by security or isolation barriers. It is a widely used system in the U.S., and around the world.

How It Works...

The Alpha Communications┬« / Haven SC-100 system permits hands-free, 2-way communication between the booth attendant and the customer. Vox circuitry facilitates ongoing, clear, 2-way conversation at all times - as if the two parties were together in the same room.

The SC-100 provides clear communication even in environments with high ambient noise by shaping the sound for maximum intelligibility. Its compression circuitry decreases loud, annoying sounds.

How To Install...

Installation of the SC-100 is a very simple, one-person operation. All that's needed is a 3.25 to 3.50 inch round cutout in the barrier. Four fasteners and two rubber gaskets needed for mounting are supplied. Please specify barrier thickness when ordering. If you have a 4.00 inch diameter opening, please order the model# AP-4 adapter plate. For 5 inch diameter opening, please order the model# AP-5 adapter plate.

The front face and housing are easily mounted on opposite sides of the barrier using the fasteners supplied. The rubber gaskets prevent slippage and protect the barrier surface. The electronic section is then inserted into the housing and fastened in place. 

Note choice of continuous-duty, 120-Volt AC power supply stepped down to 18 Volts (SC-100 series), or rechargeable lithium ion battery operation (SC-100L series).
