Night Ringer Connection Either a standard telephone (analog) ring signal (90 - 105 V AC, 20 - 30 Hz) or an external contact closure activates the night ringer function of the amplifier. To activate the night ringer using standard telephone (analog) ring, connect the analog station's tip lead to the TEL RING "T" terminal and connect the ring lead to the "R" terminal. If using an external contact closure, connect the closure pair across the CONTACT RING terminals (not polarized).The night ringer follows the cadence of the activating signal.
Bridging Inputs Bridging permits two amplifiers to be used in tandem with one another to increase the total output power of the system, thereby permitting additional speakers to be added (see Figure 6). For example, when two
NOTE: You cannot bridge more than two TPU250 amplifiers at one time.TPU250 amplifiers can only be bridged with other TPU250 amplifiers.
Input Cover Replacement When all connections are made, remove an appropriate knockout on the input cover. Replace the cover and tighten the screws while dressing the wires through the knockout hole.
