Siemens SLT-1 Installation Instructions

Installation Instructions
Model SLT-1
Leased Line/Municipal Tie Module

OPERATION

The Model SLT-1 module from Siemens Industry,
Inc., is used with the SXL-EX System to provide
connections for Leased Line and/or Municipal Tie.
Either or both connections can be used. Terminal
Block 1 (See Figure 1) provides the connection to
TB3 on the Main Board.
If the green LED (labeled DS1) on the module is
pulsing, it indicates that the module is active.
Effective with SLT-1 Rev. 1.1 and higher, and
SXL-EX Rev. 2.0 or higher, the SLT-1 will ener-
gize the municipal tie connection for one minute
after the last alarm received at the panel. Mod-
ules with firmware below this level will energize
the municipal tie connection until the panel is
reset.
With SLT-1 Rev. 1.1 and higher and SXL-EX Rev.
2.0 or higher, the municipal tie box can be reset
before the panel is reset. The SLT-1 continues to
energize the Leased Line connection until the
panel is reset for all firmware versions.
The SLT-1 causes a trouble on the display panel
when any of the following three conditions
occurs:
1. There is an open on the data line.
2. No SLT-1 module is connected to the System,
though there is an address for the module in
the System configuration.
3. An SLT-1 module is connected to the system,
but there is no address for it in the System
configuration.
