The Notifier MPS Addressable Series manual stations provide reporting for the NFS-320C, NFS2-640, and NFS2-3030 fire alarm control panels; NFW-MPS series manual stations provide reporting for FireWarden series panels. These high quality, die cast metal manual stations include screw terminal connections, and integrated break-glass rod. The alarm contact for the manual station is rated for 1A, 24VDC. The contacts are gold plated to avoid the risk of corrosion. The MPS Series manual stations are available as single or twostage for addressable systems. Models N-MPS-SA/SAC are single-stage manual stations. Models N-MPS-2AC/2A (two-stage models) are similar to the N-MPS-SC (single-stage models) except they contain an additional 2nd Stage normally open keyswitch. A 2nd stage key is supplied with each unit to activate the 2nd Stage key-switch.
