Page 13: Physical Installation
Model 2 is approximately 910 feet (278m). Wind speed and direction often affect the propagation of sound from the siren. Consequently, the direction of the prevailing wind may also be a factor to consider when selecting the installation site(s) of a small, one or two-siren system. - Page 14 Figure 3-1. Mounting Plate Drilling Detail (d) Lay the siren mechanism on its side and attach the three legs to the mounting plate using three angle iron clips and six 1/2"-13 nuts and bolts. Attach the legs through three .75" X 1” slotted holes indicated in figure 3-1.

3. Install conduit between the disconnect switch and the electrical power source. If the siren is installed on a utility pole, add an entrance cap to the end of the conduit, as shown in figure 3-2. 4. Route two wires of the proper size from T1 and T2 in the RC2W, through the conduit to the siren motor leads. -
Page 20: Section Iv - Circuit Description
SECTION IV CIRCUIT DESCRIPTION 4-1. SIREN CONTROL DESCRIPTION The Model RC2W is used to operate a Model 2 Siren. The RC2W is a motor starter that switches the power to the Model 2 siren. The RC2W requires a siren controller to provide Steady and Wail type siren signals typically used for warning applications. The siren controller will hold a contact closed to activate the RC2W for a Steady signal and will cycle the contact open and closed to create a Wail signal. -
