About the Crestron SIW-100-USB
The indicator uses an acrylic lens with edgelit RGB LEDs and is clearly visible at 50 ft (15 m). When connected by USB to a room scheduling touch screen, it alternates between red and green to show whether the room is available. It works with TSW-70 and TSW-80 series touch screens, and custom functionality is possible when it is connected to a Crestron control system.
There are two ways to connect it. A USB 2.0 device port (micro USB Type B) links it to a TSW-70 or TSW-80 touch screen, with a plenum-rated 6 ft (1.83 m) micro B to A cable included, and a TSW-80 connection needs the included adapter. Alternatively it runs as a Cresnet client on the control system, set with a CNET ID button behind the bezel. It draws 1.2 W from USB or 2.4 W from Cresnet at 24VDC.
The SIW-100-USB mounts on the wall over a single-gang electrical box or plaster ring. It has a metal bracket, a replaceable acrylic lens and a magnetically held grey plastic bezel, measures 6.41 in. (163 mm) high, 2.79 in. (71 mm) wide and 2.16 in. (55 mm) deep, and projects 2 in. (52 mm) from the wall. The included adapter can also convert an existing SIW, SSW or SSC series sign from USB-A to USB-C for TSW-80 touch screens.

Questions about the Crestron SIW-100-USB
What is the Crestron SIW-100-USB kit?
It is a wall mounted room availability status indicator kit. It includes the SIW-100 indicator, which lights green or red to show whether a room is available, and an ADPT-USB-USB-RA USB-C to USB-A adapter for connecting to TSW-80 series touch screens.
Which touch screens does the SIW-100-USB work with?
It is compatible with TSW-70 and TSW-80 series touch screens over a USB 2.0 connection. A TSW-80 series touch screen needs the ADPT-USB-USB-RA adapter, which is included in this kit. It can also connect to a Crestron control system over Cresnet instead.
How far away can the indicator be seen?
Crestron states that the SIW-100-USB is clearly visible at 50 ft (15 m). It uses an acrylic lens lit by edgelit RGB LEDs, alternating between red and green to show room availability when it is connected to a room scheduling touch screen.
How is it powered?
It takes power from its connection: 1.2 W at 5V from USB when connected to a touch screen, or 2.4 W at 24VDC when running on Cresnet. Heat dissipation is 4 BTU/hr on USB power and 7 BTU/hr on Cresnet power.
Can the included adapter be used with an older sign?
Yes. Crestron says each ADPT-USB-USB-RA adapter can convert an existing room availability sign in the SIW, SSW or SSC series from USB-A to USB-C, for compatibility with TSW-80 touch screens. The adapter is 6.00 in. (152 mm) long.

Crestron's advertised price for the SIW-100-USB in Ireland is €263 plus VAT, which is €323.49 including VAT at 23%. It does not include delivery, installation or programming, which we quote separately. Tap Request a quote for a written quote.

Does the SIW-100-USB come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the SIW-100-USB develops a fault, contact us and we will handle the claim with Crestron. If we installed it, our workmanship is guaranteed for the lifetime of the system.
Is the SIW-100-USB in stock?
We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.
Can I buy the SIW-100-USB without installation?
Yes. We supply Crestron to end users, with or without installation. Like most Crestron devices of this type, it needs setting up or programming before it works in a system, and we can quote for that too.
