Description
The Simplex RMS-1T-LP Dual-Action Pull Station is a conventional fire alarm initiating device supplied in the Simplex product line. It uses a rugged low-profile pull-station design with a lift-and-pull dual-action mechanism, requiring the protective flap to be lifted before the alarm handle can be pulled.
The RMS-1T-LP uses an SPST snap-action switch with terminal-block connections. The RMS platform is manufactured by RSG/Aames Security and is included in Simplex/Johnson Controls product catalogs for conventional manual fire alarm applications.

Dual-Action Operation
The -LP suffix identifies the dual-action Lift-and-Pull configuration.
Operation requires two actions:
- Lift the protective flap.
- Pull the alarm handle downward.
The underlying RMS-1T station uses a single SPST contact, while the LP assembly adds the second physical action required before the pull handle can be operated.
This configuration helps reduce accidental activation compared with a basic single-action pull station.
Lift-and-Pull Mechanism
The Lift-and-Pull assembly distinguishes the RMS-1T-LP from the standard RMS-1T.
RMS-1T: Single-action configuration
RMS-1T-LP: Dual-action Lift-and-Pull configuration.
Simplex’s product catalog specifically describes RMS-1T-LP as “Manual Station, Dual Action.”
Related RMS Models

RMS-1T-LP: Dual-action Lift-and-Pull station

Product Documentation
The Simplex 2023 Product Catalog specifically lists:
RMS-1T-LP — Manual Station, Dual Action.
The 2024 Autocall/Johnson Controls product catalog similarly lists RMS-1T-LP as a dual-action manual station within the RSG/Aames Security manual-station family.
The underlying RMS-series documentation further identifies RMS-1T as the single-contact model and -LP as the Dual Action option, confirming the configuration represented by RMS-1T-LP.
