BEFORE INSTALLING
This information is included as a quick reference installation guide. Refer to
the control panel installation manual and the SWIFT Wireless Manual for de-
tailed system information. If the modules will be installed in an existing op-
erational system, inform the operator and local authority that the system will
be temporarily out of service. Disconnect power to the control panel before
installing the modules.
NOTICE: This manual should be left with the owner/user of this equipment.
GENERAL DESCRIPTION
The WSK-RELAY Relay Module is intended for use with a wireless gateway or
wireless fire alarm control panel (FACP). It allows a compatible control panel
to switch discrete contacts by code command. The relay contains one isolated
set of Form-C contacts, which operate as a SPDT switch and are rated in ac-
cordance with the table in this manual. A single relay module may be used to
activate only one output device. Two relay modules must be used in parallel to
activate multiple devices such as a NAC expander. Circuit connections to the
relay are not supervised by the module. The device communicates through a
robust, bi-directional mesh network to the gateway and/or FACP. Rotary dial
switches are provided for setting the module’s address. The module has a
panel controlled LED indicator. (Figure 1)
FACEPLATE
The faceplate includes a magnet for activation and tamper resistance (Figure
2). The faceplate magnet activates communication to the panel, therefore, the
faceplate must be installed for the module to work properly. The magnet also
activates a supervisory tamper fault at the panel if the nameplate is removed.
Do NOT remove this magnet. The faceplate for a wireless module CANNOT be
replaced with the faceplate of a standard wired module.
