More about the HC-3
The optional C-LOCK2 password lock makes the caller enter a code before the coupler stays on the line.
We also build custom versions, such as a call timer that hangs up after a set time, a touch-tone handshake when it answers, or fully manual operation that answers whenever power is on. Ask us about yours.
The HC-3 was formerly called the AC-3a.
