EVS Device Installation Installing the EVS-INT50W
4.3.9 Backup Battery for EVS-50W
The following steps explain how to connect the batteries (refer to Figure 4.19):
1. Connect the black wire of the battery harness to the (-) side of the battery #2.
2. Connect the jumper wire provided form the positive (+) side of battery #2 to the negative side of battery #1.
3. Connect the red wire from the battery harness to the positive (+) side of battery #1.
4.3.10 Calculating Current Draw and Standby Battery
This section helps you determine the current draw and standby battery needs for your installation (18 ampere hours max. will fit in cabinet).
These capacities have a built-in 20% derating factor. Complete the remaining instructions in Table 4.1.
Batteries larger than 18 AH will not fit in the main control cabinet, and must be housed in the RBB Accessory Battery Cabinet. The system
supports a maximum of 33 AH batteries.
4.4 Installing the EVS-INT50W
This section provides information on how to install the EVS-INT50W for use with the EVS Series products. The EVS-INT50W Internal
Amplifier can fit inside the 5820XL-EVS or 6820EVS cabinets. It is used to amplify the audio message for distribution throughout the facil-
ity for the Emergency Voice System.
