Additional TH Modules
Add TH Modules to the Main Module to monitor additional racks. The Main Module can support a maximum of 32 TH Modules (with additional power supplies).
Adding power supplies:
The first time a TH Module receives power, it requests a unique
identification address from the Main Warning Module. It uses this address to
communicate with the Main Module. If the TH Module is not part of the system when it receives power for the first time, it cannot ensure that its identifier is unique, and communication problems may arise.
To avoid communication problems, connect the TH Module to the Main Module or a TH Module that is part of the system before connecting a stabilized power supply to the 24 VDC Input.

Connect the TH Module to the system.
Add a stabilized power supply (AP9505i)
where needed.
If the system includes beacons or devices attached to the +12 VDC or +24 VDC voltage output connector, attach a stabilized power supply (AP9505i) to the 24 VDC Input of every third TH Module.
If the system does not include any beacons or voltage output connections, connect a stabilized power supply (AP9505i) to the 24 VDC Input of every tenth TH Module.
