3.
Coordinate both master alarm panel locations with the user
facility and the other design services. When deciding upon
alarm locations, consider emergency power circuits,
Engineering Control Center data relay interface locations,
and the facility's established procedures for monitoring
alarm signals. Provide the following on plumbing drawings:
a.
Low voltage wiring and pressure switches associated
with master alarm signals and panels (on floor plans).
b.
Low voltage wiring diagram associated with master
alarm signals and panels.
c.
Tubing and/or communication cable runs from the sensor
locations to areas alarm panels (on floor plans and
medical gas and vacuum system diagrams).
B. Include an area alarm for each system at the control desk or
nurses station in all area where laboratory gas and vacuum station
outlets ad inlets are installed.

RISER DIAGRAMS
13.1
Provide diagrams for the following systems installed within the
buildings: Soil, waste and vent; reagent grade water; cold water;
hot water; hot water return; laboratory gas and vacuum; laboratory
gas and vacuum alarms; fuel gas; and storm water systems.
13.2
Riser diagrams may be shown flat, or in isometric projection. Show
story heights, size of all horizontal and vertical piping, fixture
numbers being served, and means of connection between fixtures and
the stacks and mains. Show each system complete and continuous.
14.
WATER SOFTENING SYSTEM
Provide softening equipment to serve building when total hardness
approximately 50 mg/L for building use. Provide zero mg/L hardness when
required for reverse osmosis equipment.
14.1
Softeners: Design duplex vertical, pressure type, sodium cycle
water softeners, each furnishing 50 percent of the maximum flow
rate and exchange capacity. Comply with Master Specification
15455. Regeneration shall occur no more than once per day. Provide
bypass.
14.2
Salt Storage:
A.
When softened water is needed for the entire medical center,
design outdoor storage facilities. Ensure total capacity is
large enough to accommodate 2 to 3 months supply of salt.
Locate the salt storage facility adjacent to a service road,
and preferably adjacent to the softener room.
