Potter RMS-1T-WP Weatherproof Single-Action Pull Station

The Potter RMS-1T-WP Weatherproof Single-Action Pull Station is a conventional fire alarm initiating device designed specifically for outdoor, wet, or other locations requiring a weatherproof pull station. Potter identifies model RMS-1T-WP, stock number 1000401, as a single-action, weatherproof, SPST, hex-key-reset station.

The station operates by pulling its white handle straight downward. The handle locks into the activated position, changing the state of the internal alarm contact. Resetting requires opening the front of the station and returning the handle to its normal position.

Single-Action Operation

The RMS-1T-WP is a single-action pull station.

Operation requires the user to pull the white operating handle straight downward. Once pulled, the handle locks into the activated position, providing a visible indication that the station has been operated.

Unlike the RMS-1T-WP-LP, the RMS-1T-WP does not require lifting a cover before pulling the handle. Potter identifies the two models separately:

RMS-1T-WP: Weatherproof single-action

RMS-1T-WP-LP: Weatherproof dual-action.

---

Weatherproof Operation

The defining feature of the RMS-1T-WP is its weatherproof configuration.

Potter specifically states that pull stations installed in outdoor or wet locations should use the RMS-1T-WP weatherproof unit.

This makes the model appropriate for locations where a standard indoor pull station would not provide suitable environmental protection.

The weatherproof version is supplied with the appropriate enclosure as part of the installation configuration.

SPST Alarm Contact

The RMS-1T-WP uses:

Contact Type: SPST

Stock Number: 1000401.

The SPST contact changes state when the station is activated, allowing the connected fire alarm initiating circuit to recognize an alarm condition.

Potter’s engineering specifications identify the pull-station contact as a single-pole, single-throw switch.

---

Hex-Key Reset

The standard RMS-1T-WP configuration uses a:

Reset Type: Hex-key reset.

After activation, the station is restored by opening its front and returning the operating handle to the normal position.

Potter also notes an important supervision feature: opening the station while it is in its normal state initiates an alarm condition.

This helps prevent unauthorized opening without an indication at the fire alarm system.

---

Terminal-Block Connection

Potter equips the RMS pull-station series with a dedicated terminal block to simplify field connection of the fire alarm initiating circuit.

Circuit voltage, end-of-line resistance, wiring distance, supervision method, and other initiating-circuit requirements are determined by the connected fire alarm control equipment.

Optional Dual-Action Conversion

Potter offers:

RMS-LP — Dual-Action Accessory

Stock Number: 1000480.

This accessory converts an applicable single-action station to dual-action operation.

For installations requiring a factory-designated weatherproof dual-action model, Potter separately lists:

RMS-1T-WP-LP — Weatherproof Dual-Action Pull Station

Stock Number: 1000403.

---

Installation Information

Typical installation includes routing the conventional initiating circuit into the weatherproof enclosure, terminating the conductors at the station’s terminal block, securing the assembly, and testing the station.

After installation, pulling the handle should produce the intended alarm condition at the fire alarm control panel.
