The Trigon Minipak WG is a hands free, multi-number telephone entry system for resident/visitor control. Visitors contact the desired resident by entering a simple directory code listed on the unit’s directory. The resident then grants or denies access. The resident can utilize keyless entry by using the individually assigned access code entered on the Minipak keypad. TrigonLink programming software is available for direct RS-232 interface or optional modem interface.
