Page 2: Installation
Two SP4-RMX modules can be ganged together when connecting them to an SP40/2 panel. This provides a maximum of six remote microphones providing “All Call” for the entire system. One SP4-RMX can be connected to each audio booster providing three non- alarm/general page remote microphones for that audio booster audio output. - Page 3 BGM turned on in the software. Install the SP4-RMX in a static free area and the user is to properly attach grounded wrist straps before touching any static sensitive areas. After handling printed circuit boards, the SP4-RMX should be tested in accordance with the “System Checkout” section to verify that the printed circuit boards are undamaged and functioning properly.
- Page 4 Use shielded twisted pair wire for all audio input and output wiring. Follow national and local regulations for conduit use. The shield of each cable should be connected only at one end. Each shield of each cable that connects to the SP4-RMX is to connect to the grounding terminal provided near the right edge of the chassis (see Figure 2).

- Page 9 The SP4-RMX is connected to the Audio Booster when the SPB is in the 4-wire mode. The 25V or 70V audio output of the SP40/2 is wired to the AUX IN on the SP4-RMX. The AUD OUT of the SP4-RMX is then wired to the AUDIO IN on the SPB.

Page 10: Operation
When the SP4-RMX is used to expand the remote microphone modules for the SP40/2, it is connected to the AUX IN on the SP40/2. The priority selection of the remote microphone modules will be after the SP40/2 onboard microphone (Priority 1). The priorities of the SPRM modules of a second SP4-RMX gang connected to the first will follow the priorities of the SPRM modules connected to the first SP4-RMX. -
Page 11: Priority Source
NR, TEL, BGM When the SP4-RMX is used for connecting SPRM modules to any of the SPB audio booster modules, the SP40/2 AUDIO OUT is connected to the SP4-RMX AUX IN and the SP4-RMX AUDIO OUT is connected to the SPB AUDIO IN. This means that the priority level of the SPRM-GP modules are after the digital voice messages on the SP40/2 and are considered non-alarm conditions. -
