Connections & Compatibility With Pabxs; Responsibility For Connection To Telephone Network; Ringer Equivalence Number (Ren) - Menvier Security TSD402 Installation & Programming Instructions

Regulatory Requirements
Connections
Connection terminals on the TSD402 are described as either "Safety Extra-Low Voltage"
circuits (S.E.L.V) or "Telecommunications Network Voltage" circuits (T.N.V).
The Printed Circuit Board (PCB) layout on page 11 shows the two types of circuits.
It is important that the installer ensures that T.N.V connections are only
connected to the PSTN and S.E.L.V circuits are only connected to other circuits
designated as S.E.L.V circuits.
Interconnection circuits should be such that the equipment continues to
comply with the requirements of 4.2 of EN 41003 for T.N.V circuits and 2.3 of EN
60950 for S.E.L.V circuits, after making connections between circuits.

The TSD402 is only approved for use with compatible PABX systems. Correct operation in
all circumstances is not guaranteed. If you experience any difficulties contact Menvier
