Controls And Indicators; Installation Instructions - DSC WS4920 Manual De Usuario

The WS4920 is a wireless repeater designed to extend the range of DSC one-way wireless
transmitters and to improve signal quality between the transmitter and receiver. Use the WS4920 to
remedy transmission problems caused by excessive noise or other interference, or by long distances
between devices and receivers. The maximum recommended number of WS4920's per alarm
system is 4.
Each enrolled WS4920 occupies a zone slot. The WS4920 does not increase the number of
supported wireless zones. This is determined by the control panel's wireless receiver. Only zones
requiring repeat functionality need to be enrolled on the WS4920. Ensure these zones are enrolled on
both the WS4920 and the receiver/control panel.
