Humidity: 0 to 95% non-precipitating

DESIGN

Access Requirements

The V-9945A requires a dry contact closure for activation of each tone. (If both tones will be used, two closures are required). The closures may be in the form of night ringing relay contacts, time clock contacts, a standard normally open switch, or equivalent.

Coverage

Refer to the following Table for speaker coverage. The first number given is the side to side distance for mounting the speakers. It is also the distance in front of the speaker that you can expect to hear a good quality signal. The second number is the area being covered in square feet.

Location Distance Area
Quiet 220 ft. 48,400 sq. ft.
Moderate 120 ft. 14,400 sq. ft.
Noisy 40 ft. 1,600 sq. ft.
Very Noisy 20 ft. 400 sq. ft.

Equipment Requirements

A system using the V-9945A will consist of the following:

Access equipment (See Design Section)
V-9945A (Qty. determined in Coverage Section)
-24Vdc power supply (included with horn)

INSTALLATION

General

These instructions cover only the installation procedure for the Valcom V-9945A. Please consult practices for other equipment if any other equipment is being used.

Installation

Precautions

All precautions have been taken at the factory to insure that the equipment functions properly. To insure proper operation and to prevent equipment damage, please observe the following:

Unplug the power supply before making any connections to the unit.
Do not apply power to the unit until all connections have been double checked.

Attaching Speaker to Base

NOTE: For ease of installation, the base can be attached to the speaker before or after the base is mounted.

Loosen position adjustment knob.
Insert the ball of the base into the socket of the speaker.
Tighten the position adjustment knob.

Mounting

The V-9945A should be mounted 12′ to 25′ high in the area requiring signaling. The unit can be mounted to a wall, a beam, or an electrical box.

Mount the base to a wall using the two holes provided. Knockout holes are provided for punch out should additional holes be desired.
A “C” clamp is provided with the ringer to allow mounting to a beam. Place the bolt through the hole in the bottom of the base to secure the “C” clamp to the beam. (See Figure 2).
Connection to an electrical backbox is accomplished by channeling wire through the ball of the base (see Figure 3) and making appropriate connections. The base has holes punched for a double-gang square box, but by punching out additional knockout holes, the base can be mounted to a single-gang or octagon box.

The V-9945A may be rotated or moved up and down to obtain the desired position by loosening the knob (see Figures 2 and 3) at the bottom of the unit approximately 1 turn. Make required adjustment and re-tighten knob.

Lead Designations

Black Ground (+)
White -24 Vdc
Red Warble tone access
Green Common
Brown Single tone access

Connections

Connections should be accomplished using twisted pair telephone wire. The power supply should be located within 500 ft. of the horn.

Connect negative (-)(-24 Vdc) lead of the power supply to the white lead; connect positive (+)(Gad) lead of the power supply to the black lead.
For warble tone access, connect contact closure between red and green.
For single tone access, connect contact closure between brown and green.

Connections for both single tone and warble tones may be made to the same speaker.

OPERATION

General

The V-9945A is a horn speaker containing circuitry to generate single and dual electronic tones, as well as a 5 watt amplifier and volume control. It also contains a timer to interrupt the warble tone signal (1 second on, 5 seconds off). When the red and green leads are connected together (through a contact closure), the warble tone and interrupter circuits are activated. When the brown and green leads are connected, the circuitry for the single tone is activated. If both closures are applied, the single tone will be sent.

TECHNICAL ASSISTANCE

When trouble is reported, verify that power is being supplied to the unit and there are no broken connections. Check voltages for proper polarity on the crossconnect block.

A lineman’s test set, several clip leads, and a VOM may be necessary to effectively troubleshoot the unit.

Table 1 identifies symptoms of some possible problems with solutions. If your problem is listed, perform the actions indicated.

If the trouble has not been located, continue totroubleshoot by substituting a spare unit for the suspected unit.
