VIKING Electronics 25AE-70V 70Volt Paging Horn Instruction Manual

Cost Effective Paging Horn for 70V Paging Systems

The 25AE-70V paging horn provides economical paging coverage for 70 Volt paging systems. In outdoor factory or warehouse environments, 25AE-70V paging horns are the best method of producing understandable sound. In these environments the directional design allows the installer to focus the sound cone down aisles and toward work areas.

The 25AE-70V paging horn provides a built-in step-down transformer for use with 25V or 70V paging systems such as Viking models PA-30, PA-60, PA-250, PA-250-IP and PP-250. The transformer has a range of 5 separate switch selectable power taps, which can be used to adjust the volume of each speaker. These higher voltage distributed audio paging systems also have the advantage of being able to connect more speakers using lighter gauge wire runs while having less volume lost in wire resistance. This saves wiring costs compared to 8 ohm systems.

Installation

The 25AE-70V paging horn is designed to be surface mounted to any rigid surface. For outdoor applications, it is recommended to mount the paging horn underneath an eave, and have the horn pointed downward, to keep water from pooling in the horn.

Wiring

A. 70V Paging System

Step 1. Connect the RED (+) and GREEN (-) wires to the 70V output of a paging system.
Step 2. Use the 70V scale on the back of the 25AE-70V Paging Horn to manage power and adjust the volume by turning the selection knob to the .62W, 1.25W, 2.5W, 5W, or 10W setting.

B. 25V Paging System

Step 1. Connect the RED (+) and GREEN (-) wires to the 25V output of a paging system.
Step 2. Use the 25V scale on the back of the 25AE-70V Paging Horn to manage power and adjust the volume by turning the selection knob to the .08W,

.16W, .31W, .62W, or 1.25W setting.

C. Use with Viking Model PA-30 or PA-60 Amplifiers

Viking models PA-30 (DOD 489) and PA-60 (DOD 493) have the ability to drive 25V and 70V paging speakers. This is achieved by bridging together two differential 8 ohm outputs to get a high voltage output (see DOD 489 and 493 for additional information). The achieved output voltage is actually between the 25V and 70V standards. Because of this, the 25AE-70V paging horn shows a third scaling option for the transformer tap selection knob called “VIKING WATTS” in which there are six settings ranging from .16W to 2.5W. Use this scale to manage power handling and adjust volume of each 25AE-70V paging horn. Best results are achieved if the power sum of all 25AE-70V paging horns used does not excessively exceed the power output of the PA-30 or PA-60 amplifier.

Step 1. Connect the RED (+) and GREEN (-) wires to the “70V OUT” screw terminals of the PA-30 or PA-60.
Step 2. Use the “VIKING WATTS” scale on the back of the 25AE-70V Paging Horn to adjust the volume by turning the selection knob to the .16W, .31W, .62W, 1.25W, or 2.5W setting.

Other Viking Speakers

Cost Effective Speakers for Indoor and Outdoor Use

The 300AE paging horn provides a direct voice coil connection for use with 8 ohm paging systems such as Viking models PA-2A, PA-15, PA-60, HF-3W, DVA-2WA and M2W. Even though its 30 watt rating is greater than some lower power paging amplifiers provide, the 300AE is an excellent choice because it is more efficient than Viking’s smaller 25AE paging horn. In other words, the larger 300AE only needs 1 watt of power to play as loud as 2 watts being driven into the smaller 25AE paging horn.

The 300AE paging horn also provides a built-in step-down transformer for use with 25V or 70V paging systems such as Viking models PA-30, PA-60, PA-250, PP-250 and PA-250-IP. The transformer has a range of power taps that are selectable with a 6 position rotary switch, so that installers are able to independently adjust the volume of each paging horn. Higher voltage paging systems also have the advantage of being able to connect more speakers using lighter gauge wire runs and still have less volume lost in wire resistance.
