2. Integrated Building Management System (IBMS) is a complete information
delivery system that monitors and controls a variety of systems and
functions at an optimal level of efficiency.
INTRODUCTION

3. Building Management System (BMS) is a high technology system installed on
buildings that controls and monitors the building’s mechanical and electrical
equipment such as:
1.air handling and cooling plant systems,
2.lighting,
3.power systems,
4.fire systems, and
5.security systems.
BMS consists on software and hardware.
Software program, usually configured in a hierarchical manner, can
be:
a-proprietary using such protocols as C-bus, Profibus, etc.
b-that integrate using Internet protocols and open standards like
SOAP, & XML, BacNet, Lon, Modbus,
D E F I N I T I O N

4. All Buildings have some form of mechanical and electrical services in order to
provide the facilities necessary for maintaining a comfortable working
environment. These services have to be controlled by some means to ensure,
for example, that
1.there is adequate hot water for sinks,
2.the water tank is full
The cooling with ventilation and possibly heating is provided to ensure
comfort conditions wherever, irrespective of the number of occupants or
individual preferences , the security is well controlled and monitored, etc.
The purpose of a Building Management System (BMS) is to automate and take
control of these operations in the most efficient way possible for the
occupiers/business, within the constraints of the installed plant.

8. HVAC Systems (Heating, Ventilation and Air
Conditioning)
HVAC system fully integrated with lighting and access
control system so that air condition; ventilation can be
adjusted according to space usage and number of
occupants. This allows a more efficient use of HVAC
system with load balancing.
Our HVAC system come with Zoning features which
allows further control over energy consumption by only
heating or cooling used zones leaving the unused
ones. Latest development in HVAC allows you to
control and set temperatures via internet and mobile
phones.
H V A C -INTRODUCTION

9. THE PROCESS OF CONTROLLING AN HVAC
SYSTEM INVOLVES THREE STEPS.
THESE STEPS INCLUDE :
1.MEASURING DATA
2. PROCESSING THE DATA WITH
OTHER INFORMATION AND
3. CONTROL ACTION.
THESE THREE FUNCTIONS
MAKE UP WHAT IS KNOWN AS A
CONTROL LOOP .
H V A C -INTRODUCTION

10. HVAC Controls
•Primary AHU controls
•Chiller Plant Management
•Runtime Optimisation of fans and pumps
•Variable Air Volume (VAV) Systems
•BTU metering & billing system for multi-tenant
applications
•Centralized Monitoring and Control on PC based
Graphics Work Station.
H V A C -CONTROL

11. CHILLER PLANT -HVAC
•Chiller Valve ON
•Secondary Pump ON
•Primary Pump ON
•Chiller ON
CHILLER SENSOR COMPONENTS:
1.DISPLAY SENSOR
2.DIFFERENTIAL PRESSURE TRAMMITTER
3.TWO-WAY VALVE--OUTLET
Air DP switches: They are designed for
under pressure, overpressure and
differential pressure measurement of air
and other neutral gases. We use DP
switches in air-conditioning systems to
provide an indication of fan-status and
dirty filter conditions.
Liquid D.P switches: Applications
include switching on an alarm or warning
light, cutting of an electrical supply to the
pump.

12. AIR HANDLING UNITS -HVAC
The fire / smoke sensor, detects in the
event of fire, the fire damper actuator
closes the supply and the return fire
damper. Supply air fan is switched off
and Valves are closed.
CONTROL SCHEME:
The return air temperature is
measured by the temperature
sensor
The Chilled water valve is
modulated by the demand signal
from the return air temperature loop

13. Central controllers and most terminal unit controllers are programmable, meaning
thedirect digital controlprogram code may be customized for the intended use. The
program features include time schedules,set points, controllers, logic, timers, trend
logs, and alarms. The unit controllers typically have analog and digital inputs that allow
measurement of the variable (temperature, humidity, or pressure) andanalogand
digitaloutputs for control of the transport medium (hot/cold water and/or steam). Digital
inputs are typically (dry) contacts from a control device, and analog inputs are typically
a voltage or current measurement from a variable (temperature, humidity, velocity, or
pressure) sensing device.
Digital outputs are typically relay contacts used to start and stop equipment, and
analog outputs are typically voltage or current signals to control the movement of the
medium (air/water/steam) control devices such as valves, dampers, and motors.
Group of DDC controllers, networked or not, form a layer of system themselves. This
"subsystem" is vital to the performance and basic operation of the overall HVAC
system. The DDC system is the "brain" of the HVAC system. It dictates the position of
every damper and valve in a system. It determines which fans, pumps and chiller run
and at what speed or capacity.
DIRECT DIGITAL CONTROL

14. DDC SYSTEMS -FUNCTIONS:
THE FUNCTIONS THEY PROVIDE IS AS SIMPLE AS
CONTROLLING ROOM TEMPERATURE IN AN OFFICE
TO LINKING TOGETHER AN ENTIRE CAMPUS OF
BUILDINGS AND THE CENTRAL POWER PLANT.
DDC CONTROL SYSTEMS TODAY HAVE BECOME THE
STANDARD IN BUILDINGS FOR MAINTAINING THE
ENVIRONMENT.
10 YEARS AGO DDC WAS A LUXURY TO OWNERS
AND BUILDING MANAGERS NOT TODAY.
WE HAVE PROVEN TIME AND TIME AGAIN THAT DDC
IS JUST AS COST EFFECTIVE TO IMPLEMENT
COMPARED TO TRADITIONAL CONTROL SYSTEMS
SUCH AS ELECTRIC OR PNEUMATIC.
DIRECT DIGITAL CONTROL

BENEFITS OF DDC
•Reduces the energy costwithout creating an
adverse impact of the building thro the staratergies
such as load shedding with optimum
•start/ stop and reduction of the operating speed of
the motor.
•It also improves the air quality
•They provide an effective and reliable building
control system

control. There are rotary actuators, electronic linear
actuators, and pneumatic actuators.

Two water level sensors ,one
placed at the top (max.) of the
tank and the other near the
bottom (min)
These two sensor outputs are
give as inputs to the unitron
controller and the output of UC
will activate an pump.
So the system is neither schedule
nor switch based but fully
automated.

A photoelectric sensor for monitoring elevator doors
Photoelectric sensors emit a narrow beam and monitor
the threshold of an elevator door with a reflector or
receiver as a reference. They provide a simple and cost-
effective method to secure the elevator door. Extra
narrow housings enable the light curtain installation in
confined locations in the door frame. AC/DC supply
sensors are available as well as features that include high
ambient light immunity and tamper-proof housings.

22. E S C A L A T O R -INTRODUCTION
An escalator combtooth assembly for an escalator
is responsive to combplate obstruction and
generates an alarm signal when an obstruction is
encountered. One or more combteeth plates are
pivotally mounted to the front or leading edge at a
combplate assembly. In response to an
encountered obstruction one or more of the plates
rotate upwardly. Electrical switch contacts
associated with the combteeth plates change
state when the plate rotates, allowing an alarm
signal to be generated. The combteeth plates
may include rearwardly-extending arms which
pass through accepting slots located at the rear of
a ledge on a main complete body upon which the
combteeth plates rest. A guide device, such as a
bolt, limits the degree of available rotation for the
plates, which are biased in an initial position,
preferably by an elastomeric member.
