manual for future reference NUMBERS 8 HORN SPEAKER W 5 WATT AMPLIFIER 8 HORN SPEAKER W 15 WATT AMPLIFIER speakers with built in amplifiers are used for one way voice paging background music and tone alerting in large indoor and and or noisy locations Model SA H5 B has a built in 5 watt amplifier and model SA H15 B has a built in 15 watt amplifier models have a built in volume control The horn speakers with built in amplifier are used in the following manner Figure 1 a zone paging application used with Wheelock Zone Page Control Module The horn speaker can also be used to provide paging when connected directly to an unused Central Office C O line port which can be programmed to function as a Ohm Audio Page Port i e does not require Talk Battery See Figure 2 All CAUTIONS and WARNINGS are identified by the symbol All warnings are printed in bold capital letters READ THESE INSTRUCTIONS CAREFULLY FAILURE TO COMPLY WITH ANY OF THE INSTRUCTIONS CAUTIONS AND WARNINGS COULD RESULT IN IMPROPER APPLICATION AND OR OPERATION OF THESE PRODUCTS IN AN EMERGENCY SITUATION WHICH COULD IN PROPERTY DAMAGE SERIOUS INJURY OR DEATH TO YOU AND OR OTHERS 1 2 notes 1 and 2 below Some telephone systems require that the C O trunk port loop start or C O line port be equipped with a trunk card page card or equipment Consult the telephone manufacturer system manual for equipment or programming required If unused C O port requires talk battery to pass audio most do then a Wheelock Zone Control is required as an interface for paging systems For single zone paging a Wheelock PRM 150

locations They are weatherproof and may be used indoors or outdoors The horn has a built in amplifier It volume controls should be set to provide horn sound pressure level SPL of at least 6 to 10dB for and 3 to 6dB for background music However the horn speaker volume should not be set so high as to cause discomfort to closest to the horn These devices should not be operated at volume levels loud enough to cause audible distortion Operation in manner may result in damage to the unit In some cases use of multiple horns set at lower volume provide better sound coverage one horn set at full volume Horns should be mounted at least 15 feet above the floor and angled downward Tables 1 2 and Figures 8 9 as a guide to determine horn spacing area coverage and sound pressure level designed for continuous operation the use of continuous tone signals at high volume is not recommended While short tone should cause no problem sustained operation in this mode may result in failure of the unit

From Horn On Axis The total system wattage requirement should not exceed 85 of the system amplifiers rated output The total system requirement is the summation of the wattage tap selections of all system speakers and horns B 4 of 8 INFORMATION SA H5 B and SA H15 B may be wall mounted by simply using the holes in the swivel base to locate and drill mounting holes ease of mounting the swivel base may be removed from the horn body Then mount the base to the surface with appropriate Slots are also provided in the base for banding straps to allow mounting to beams poles and girders The mounting base also fully adjustable in both the vertical and horizontal planes See Figure 10 These devices are not intended for use in hazardous locations as defined by the National Electrical Code NEC and the National Fire Protection Association NFPA Base 10 Loosening the wing nut will allow for both pitch and rotation of the unit When adjusting horn position be careful not to lose adjusting hardware
