Please keep this instruction manual for future reference. MODEL NUMBER: MTH-24 GENERAL: The MTH-24 Multi-Tone Horn is a loud, attention getting alert designed for use in noisy and/or large locations where two different audible appliances are required at one location. The MTH-24 functions as a telephone extension alert because it provides a pulsed warble tone (1 second on and 7 seconds off) which can be activated by a telephone systems interrupted or continuous dry contact closure. Additionally, it functions as an auxiliary alert because it also provides a steady tone which follows the contact closure of a door/service push-button, time clock, alarm systems, etc. When both alerting tones are activated, the steady tone will take priority over the warble tone. If required, the warble tone can be used as the auxiliary alert, and the priority tone can be used as the telephone alert. As shown in Figure 1, the MTH-24 consists of dual tone generator, amplifier, timer for the warble tone, priority circuit and volume control built-in to a weather resistant speaker horn for indoor and outdoor use. A Wheelock RPS-2406, 24VDC power supply is included to power the MTH-24. Multiple units can be connected in parallel where required. NOTE: All CAUTIONS and WARNINGS are identified by the symbol .
