RSG RMS-3T-KS SPDT Pull Station with Key Switch

The RSG RMS-3T-KS is an SPDT terminal-block-connection manual pull station with an integrated Key Switch (KS) for two-stage activation. Furthermore, it suits commercial fire alarm circuits requiring pre-signal control.

First, the integrated key switch arms the second stage of the alarm. Then, pulling the lever triggers a general alarm only after the key turns. As a result, staff can investigate before a full evacuation begins.

In addition, pre-signal operation depends on the panel’s programming. However, the SPDT switch makes either polarity available to the second stage. Therefore, confirm the panel supports two-stage initiation before specifying.

RSG RMS-3T-KS Option Detail

The KS option adds a panel-mounted key switch to the standard pull lever. Furthermore, the SPDT switch supports normally-open and normally-closed contacts. As a result, the station supports controlled pre-signal activation in either wiring style.
