Single Action Type

Dual Action TypeDescription
The FMM01U series are die-cast metal fire alarm pull stations available in either single or dual action configuration with Single Pole Single Throw(SPST) contacts. Also either lead wire or terminal strip connection is available in the series. The normally-open contact, which closes when thepull station is activated, is rated for 1A, 30VDC. The contacts are gold plated to avoid the risk of corrosion. The FMM01U series station can bereset by dedicated key after activation.
Applicable addressable modules are Miniature Contact Module (FRRU004-MCM), Single Contact Module (FRRU004-SCM4) and Dual Contact
Module (FRRU004-DCM4).
The FMM01U series are operated by pulling the handle on the front of the station as far down as it will go, at which point the handle locks intoplace and is easily visible from up to 50 feet. The handle is reset by opening the station with the key, placing the handle in the normal uprightposition and re-locking the station. On the dual action modules, the push rod rotates inward allowing the pull handle to be grasped in one handedmotion.
The FMM01U series can also be used for manual release stations to activate gaseous fire suppression systems.
