Motorola Solutions Branded SB9600 Siren/PA Configuration/Programming.
The Siren/PA is shipped pre-wired for 100 W operation. It can be rewired for 65 W, 75 W, or 130 Wpower levels. To change to another power level, perform the following:
1. Open the Siren/PA connector cover to gainaccess to the two-connector speaker lead. Donot change the speaker common lead (pin 20). The other lead is connected to pin 35 (for 100W operation).
2. Using an appropriate pin removal tool, extract pin 35 and move it to one of the following pin
locations:
- pin location 36 for 75 W operation
- pin location 28 for 65 W or 130 W operation
3. For 65 W or 75 W operation, no further changes are required. Reassemble the connector.
4. For 130 W operation, you must parallel two 11ȍspeakers, each rated at 65 W minimum. Proper phasing of the two speakers is important when connecting two speakers in parallel, wire similar speaker terminals together to ensure maximum loudness and prevent"deadspots." For example, if the terminals are marked "1" and "2", connect the terminals marked "1" together and connect those wires to one speaker lead. Connect the terminals marked "2" together and connect those wires to the other speaker lead.
5. When the Siren/PA is configured for dual speaker, 130 W operation, it is necessary to remove a resistor and move two jumpers to set the correct power level. Remove the Siren/PA cover,and locate resistor R219 (0ȍ). This resistor should be removed for 130 W operation. Locate jumpers JU100 and JU101. These jumpers should be installed for 130 W operation.
6. Close and reconnect the Siren/PA connector cover.
