[15] OPTIONAL ACCESSORIES
[15.1] RTS451/RTS451KEY REMOTE TEST STATION
The RTS451/RTS451KEYA Remote Test Station facilitates test of the alarm
capability of the duct smoke detector as indicated in the RTS451/RTS-
451KEYA manual. The D4120A duct smoke detector can be reset by the
RTS451/RTS451KEYA. To install the RTS451/RTS451KEYA, connect the
device as shown in Figure 12; wire runs must be limited to 25 ohms or less
per interconnecting wire. If a system control panel is used, the panel itself
may require testing.
