Siemens MSM-K-WP — weatherproof die-cast metal manual fire alarm box with keyed reset, catalogue number 500-698217.
The MSM series answers the code requirements for a manual fire alarm box in a rugged cast housing rather than moulded plastic, with raised lettering and every surface painted or plated to inhibit corrosion. Reset is by key, and it is the same key the Siemens control panels use, so one key serves the panel and the stations.
- Shipped complete with backbox, where the backbox is optional on the standard models
- SPST switch rated 10 A at 120 VAC, all connections to a terminal block
- Supplied with two reset keys
- Weatherproof station 3.20 in. wide by 4.75 in. high by 2.75 in. deep
- UL and ULC Certified, USCG and CSFM approved
- For Siemens conventional zones, or addressable zones through a TRI-Series module
MSM-KD-WP, 500-698218, is the double-action weatherproof station. MSM-K, 500-698215, is the same keyed station without the weatherproof housing, and there the surface backbox is the separate MSM-BOX, 500-698221. MSM-EXP is explosion-proof and the only model with a DPDT switch.
