Simplex 2099-9803 — replacement breakglass for Simplex double action breakglass manual stations.
A double action breakglass station is operated by striking the front-mounted hammer to break the glass, which exposes the recessed pull lever; the lever then behaves as a single action station and latches out of the housing as a visible indication. The glass is consumed in that operation, so the station is not back in service until a new pane is fitted and the station is reset with a key.
