RSG RMS-3T-DAH SPDT Pull Station with Break Glass Adapter

The RSG RMS-3T-DAH is an SPDT terminal-block-connection manual pull station with the Door-Activation/Break-Glass Adapter (DAH) option. Furthermore, it suits commercial fire alarm circuits where a break-glass adapter is preferred over a standard cover.

First, the user strikes and breaks the glass rod. Then, the lever pulls down to activate the alarm. As a result, the broken-glass cue confirms a deliberate pull.

In addition, break-glass adapters are common where dual-action covers are not preferred. However, replacement glass rods are inexpensive and tool-free to swap. Therefore, stock spare RMS-GR rods for fast post-activation restore.

RSG RMS-3T-DAH Option Detail

The DAH option adds a break-glass adapter housing to the standard lever. Furthermore, the SPDT switch supports normally-open and normally-closed contacts. As a result, one station can wire to either polarity convention.
