The TTD-16 may be set up to answer on 1, 2, 3 or 4 rings. The caller must first enter a 4-digit password to gain access to the system. The password is assigned using DIP switches inside the unit.
Once access to the system is obtained, each of the 16 relays can be easily controlled. A voice driven help menu is available to guide the user through the required steps for control of the individual relays. Each relay may be individually turned on or off, as required. The status of all 16 relays can be reported at any time.
A front panel LED is provided for off-hook status, indicating when the system is in use.
Connection to the telephone line is via a standard RJ-11 telco connector on the rear panel. Relay connections are made via screw clamp terminal blocks for each of the 16 relays.
