Attractive and durable, Mircom’s MS-400U Series of manual stations provide manual fi re reporting. The MS- 400U Series manual stations are non-coded, single or double action devices which initiate an alarm when pulled. Resetting is accomplished by inserting a 1/8” screwdriver from the front. The handle, once pulled will remain open and cannot be reset without utilizing the screwdriver. The MS-400U Series manual stations are constructed of durable aluminium and fi nished in red. An abrasion resistant label with large, raised letters provides clear legible instructions. The model MS-402U (two stage) is similar to the MS401U (single stage) except it contains an additional General Alarm (G.A.) N.O. switch. For safety reasons, the G.A. switch is only accessible after the handle has been pulled. A special key is supplied with each unit. The model MS-405U is similar to the MS-401U except it has an additional N.O. switch. The model MS-406U is similar to the MS-402U except it has an additional N.O. switch. The model MS-407U is similar to the MS- 401U except it has an additional N.C. switch. The model MS-408U is similar to the MS-402U except it has an additional N.C. switch. All manual stations can be easily converted from single action to double action station by the addition of the MS-DA double action lever.
