Specifications
Size and Capacity: Accommodates 5
users (36" models) or 8 users (54" models) at a time, using less water, energy,
and space than lavs equipped with conventional faucets. The sectional sprayhead module
(nonsectional is optional) is controlled by a pushbutton which actuates an air valve (hand
or foot control models), or by an infrared sensor-actuated solenoid valve. Flow restrictor
keeps flow rate constant at 0.5 GPM per station for all pressures. Operating range is
20–100 PSI.
Bowl and Pedestal: All exposed
materials are type 304 stainless steel polished to a #4 finish. Bowl, pedestal, access
panels, frame, foot control housing; support tube and sprayhead are heavy guage stainless
steel. Exposed fittings are chrome plated.
Vandal Resistance: Bowl and support
tube are an integrally welded assembly with the support tube welded to extruded flange
from bowl. Spray nozzles and pushbuttons/infrared sensors are secured to unit from inside
the sprayhead module. Air valves/solenoid valves are safely concealed inside the
washfountain. Access panels are removable only with a hex key. All supply and waste
connections are concealed within the pedestal which is secured to the floor with anchor
bolts (supplied by others).
Barrier-Free (ADA compliant)
Standard Height 54" Models Only:
The standard height 54" Sentry washfountain with hand or infrared control is designed
to comply with all ADA guidelines on reaches, clearances, and operation.
Standard Equipment
Valves and Fittings: In addition to
the bowl and pedestal, the following valves and fittings are standard: manual mixing
valve, check stops, and strainers. Check valves are 1/2" NPT female.
Activation Controls
Air Valve Hand Control: Each
pushbutton pneumatically actuates a non-hold-open air single temperature valve with field
adjustable timing from 0–60 seconds. Factory set at 10 seconds minimum for ADA. Each
pushbutton actuates one valve which in turn activates one station (sprayhead nozzle).
Air Valve Foot Control: Each
pushbutton pneumatically actuates a hold-open air single temperature valve with slow
closing upon release of foot pressure.
Activation
Controls (continued)
Infrared Control: Each spray nozzle is
controlled by a separate solenoid valve. Hands placed within the washfountain bowl are
detected by an infrared sensor module which activates a flow of tempered water from one
spray nozzle. Shut-off is automatic after hands are removed from the detection area.
The infrared sensor module uses two zone-focused infrared
transmitting beams—each creating a detection area not exceeding the bowl perimeter.
The detection range projects 6–9 inches forward at a 30° angle to each side, and
reaches 15° below horizontal. The infrared sensor is not affected by varying color tones
or darkness. Direct sunlight or bright washroom lights (up to 10,000 ft. candles) will not
activate the system. Infrared models also include solenoid valves and a low voltage
transformer as standard equipment:
- Solenoids—24V, 50/60 Hz, 3/8"
NPT. Few moving parts, and resistant to most chemicals and minerals in municipal water.
- Low Voltage Transformer—Class II,
110/24 VAC transformer with integral universal mount. Location and junction box (by
others) per local electrical code.
