SS16 to End Devices
The SS16 allows for connection of up to 16 devices. The devices can be any of the REDy Corp standard
stations listed in table 1. They can also be direct connection of 25V audio transformer/speaker, or UTP
camera (utilizing a video balun). Typical installations will connect these types of devices to one of the
standard room stations prior to connecting to the SS16, however it is not mandatory. When connecting
speakers the following limits must be followed. No more than 25 watts per port and no more than 35
watts peak per SS16 can be connected. The required wire to go from the SS16 to the end devices is CAT5.
The wire is terminated at the SS16 with an RJ45 plug of the appropriate type for the CAT5 cabling being
used. The device end of the wire can be left as a pig tail or terminated with a RJ45 connector depending
on the application. Figure 19 below shows where the devices are connected to the SS16. The diagram
found on the cover of the SS16 lists the port numbers as well as the function of each pin within each
connector.
For installations needing to deploy motion sensors etc, requires wiring them into a CS150 call station
before connecting back to an SS16 (See Figure 22). The SS16 also pr12 VDC power at each
device port for powering some sensor devices, with the combined current consumption of all 16 ports
limited at 150 mA. It is recommended that if more than a few sensors per SS16 are required, that the SS16
be provided with local power via the 2.1 mm DC jack on the side of the SS16. If this is not practical, or
the +12 VDC supply is not appropriate for the devices being used, then a completely separate power
source must be used.
When power is applied to an SS16, the green status LED (shown on the right side of figure 19 beside the
DC input jack), will flash at a steady rate, indicating the unit is operating properly.
Sensors can be connected directly to an SS16 device port, as long as the following specific limitations are
understood.
•
Sensor/device must provide a normally open contact during idle going closed during activation.
Normally closed contacts are not supported unless going through a CS150 call station.
•
Contact closure provided by the sensor will be treated like a normal call-in to the system, and will
not have sensor input status.
•
Sensor/device activation time must be a minimum of 50 milliseconds to be recognized.
