Two-Tone Indoor Siren (490-0490A) Installation Faxback Doc. # 15177 WARNING: This alarm is intended for an indoor application. The sale and use of sirens for a mobile application is prohibited in California and some other states. It is the responsibility to check the local regulations before installing the siren. 1. Remove the mounting adapter from the back of the siren. 2. Locate a suitable flat surface for mounting the adapter. 3. Mount the adapter on the surface, using the three supplied screws. Be sure that the adapter is positioned with the arrow pointing up, so the siren mounts flat. 4. Route the wiring from the security system through the adapter, and connect the wiring to the siren. If the security system has two alarm outputs, connect one to YELP and the other to STEADY. If the security system has only one alarm output, connect it to either YELP or STEADY. 5. Connect the common lead coming from the security system to COMMON. 6. Place the siren on the mounting adapter, with the mounting holes aligned with the mounting pins. Rotate the siren clockwise to secure it. (LB/all-05/08/95)
