Initiating Devices - Manual - Siemens System 3 Manual

7. INITIATING DEVICES — MANUAL
MS-51/501
Manual fire alarm station. Manual stations are
recommended for use with automatic fire
detectors. If a fire is observed before automatic
detector response, the manual activation of the
station results in the same system response as
automatic detection. Manual stations should be
installed throughout the accommodation spaces,
the service spaces, and the control stations.
One manual station should be located at each
exit. The stations should be readily accessible
in the corridors of each deck so that no part of
the corridor is more than 60 feet (20 meters)
from another manual station. (See Spec Sheet
Catalog No. 6183.)
Section III — Equipment Descriptions and Functions
MSM Series
The MSM Series manual stations feature a
rugged diecast metal housing that satisfies
both architectural and code requirements
for manual fire alarm box initiation devices.
The MSM-Series box features keyed reset
using the same key as the control panels.
The MSM Series models are low-profile
with all surfaces either painted or plated to
inhibit corrosion. These boxes have raised
lettering and are shipped with two reset
keys and a break glass rod (use of rod is
optional.) Options include: double action,
institutional, weatherproof, and explosion-
proof. (See Spec Sheet Catalog No. 6184.)
