Terminal 4 (Ext. Spkr.) of the Model 4720 is designed for use with an 8-Ω, 15-W speaker. Connect the
speaker between Terminals 4 and 7 as shown in the diagram below. DO NOT cut Jumper J1 on the Model
4720. If the board has a shunt block, leave it in the right (“in”) position. An external speaker is NOT
permitted for UL commercial installations. It is only permitted in UL Residential installations. The Ademco
713 is a suitable UL Listed speaker.
