Installing the ECS-INT50W ECS Device Installation
4.4.10 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.
4.5 Installing the ECS-INT50W
This section provides information on how to install the ECS-INT50W for use with the ECS Series products. The ECS-INT50W Internal
Amplifier can fit inside the IFP-300ECS or IFP-2000ECS cabinets. It can also be adapted to fit into the IFP-2100ECS cabinet with the ECS-
AMPMT mounting kit (sold separately). It is used to amplify the audio message for distribution throughout the facility for the Emergency
Communication System.
4.5.1 Board Layout & Mounting
Mounting the ECS-INT50W
1. Remove AC power and disconnect the backup batteries from the main control panel.
2. To mount the ECS-INT50W inside the FACP cabinet below the main board, align the board with the mounting holes and secure the
board to the enclosure with the eight supplied screws.
