Digital Security Controls Ltd. 12WIFI422SCW Manuel D’Utilisation

The WIFI422SCW module provides a wireless link from the host security control panel to
the C24 Interactive gateway. This manual provides installation and setup information for
WiFi422SCW only. 

This module is compatible with the following SCW control panels: SCW9055-SM-433,
SCW9055D-SM-433, SCW9055G-SM-433, SCW9055I-SM-433, SCW9057-SM-433,
SCW9057D-SM-433, SCW9057G-SM-433, SCW9057I-SM-433.

Insert WIFI422SCW module into the SCW905X backplate. Refer to Table 1 below for
wiring details.

Figure 1: 

The WIFI422SCW module receives power from the control panel AUX output and it
communicates via the RS-422 interface on the 3G2055-SM-NA or TL2553G-SM-NA
communicators.
1. Enter section [851][920]. 
• The communicator will send a command to initiate Wi-Fi Protected Setup (WPS).
• The message “WPS Success” is displayed when setup is complete.

Please refer to the SCW9055/9057 Installation Manual to configure PGM1 to Pulse.  The
default configuration (5 seconds) is recommended.

Upon entering this section the WIFI422SCW module shall initiate WPS and connect to
the nearest Access Point (AP) also performing WPS. The LCD shall display “WPS Enroll-
ment in Progress”.
• Upon failure of enrollment, the LCD shall display “WPS Enrollment Failure”.
• Upon successful of enrollment, the LCD shall display “WPS Enrollment Success”.

Default (99)
Enter [00] to perform a factory default, this will disconnect the WiFi422SCW from the
Access Point. The installer must perform a WPS with the new Access Point in order to
enroll the router.
Once the Access Point is disconnected, the default SSID will display “X”.

Enter section [851][922] to obtain the SSID of the currently enrolled Access Point.
The keypad will display the SSID of the network that it is using. If the WiFi422SCW is
not connected to any Access Point, the keypad will display “X” to indicate the network
connection has not been created. 

Enter section [851][923] to view the Wi-Fi signal strength.
Once in this section, the keypad will display the signal strength with respect to the Access
Point it is currently using. If the WiFi422SCW is not associated with any Access Point,
the Keypad will display “X------”

This modular transmitter is labeled with its own FCC ID and IC number. When the mod-
ule is installed inside the host device and the FCC ID/IC of the module is not visible the
host device shall display the provided label referring to the FCC ID and IC of the enclosed
module. This label is shipped together with the module and it is the responsibility of the
integrator to apply it to the exterior of the enclosure as indicated below.

CAUTION: Changes or modifications not expressly approved by DSC could void your authority to use this
equipment.
This equipment generates and uses radio frequency energy and if not installed and used properly, in strict accor-
dance with the manufacturer’s instructions, may cause interference to radio and television reception. It has been
type tested and found to comply with the limits for Class B device in accordance with the specifications in Sub-
part “B” of Part 15 of FCC Rules, which are designed to provide reasonable protection against such interfer-
ence in any
residential installation. However, there is no guarantee that interference will not occur in a particular installa-
tion. If this equipment does cause interference to television or radio reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
• Re-orient the receiving antenna
• Relocate the alarm control with respect to the receiver
• Move the alarm control away from the receiver
• Connect the alarm control into a different outlet so that alarm control and receiver are on different circuits.
If necessary, the user should consult the dealer or an experienced radio/television technician for additional sug-
gestions. The user may find the following booklet prepared by the FCC helpful: “How to Identify and Resolve
Radio/Television Interference Problems”. This booklet is available from the U.S. Government Printing Office,
Washington,D.C. 20402, Stock # 004-000-00345-4.
This device complies with Part 15 of the FCC Rules and with Industry Canada license exempt RSS standard(s).
Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may cause undesired operation. “
