4. Input Devices
Fire Detector
The field of fire detection has advanced to where
smokedetectors and alarm devices have combined to become life-
safety systems. The purpose of an automatic fire-alarm system is
to detect an occurrence, alert the control panel and proper
authorities, and notify the occupants to take action.
• Smoke detectors
• Heat detectors
5. Fire Sprinkler
• Sprinkler heads operate individually. Note the red liquid alcohol in
the glass bulb. A fire sprinkler system is an active fire protection
method, consisting of a water supply system, providing adequate
pressure and flow rate to a water distribution piping system, onto
which fire sprinklers are connected.

7. Fire Extinguisher System
A fire extinguisher, or extinguisher, is an active fire protection device
used to extinguish or control small fires, often in emergency situations.
It is not intended for use on an out-of-control fire, such as one which
has reached the ceiling, endangers the user (i.e., no escape route,
smoke, explosion hazard, etc.), or otherwise requires the expertise of
a fire department.

11. CCTV
(CLOSED CIRCUIT TELEVISION)
Closed-circuit television (CCTV) is the use of video
cameras to transmit a signal to a specific place, on a
limited set of monitors. It differs from broadcast
television in that the signal is not openly
transmitted, though it may employ point to point
(P2P), point to multipoint, or mesh wireless links.
12. Why Use CCTV

13. Type of camera
• Dome Camera
• Domes Installs easy in drop ceilings –
usually 2 screws
• Since a dome has a covered lens the
direction the camera is pointing is
hidden
• Dome can accommodate infra-red for
night vision
• As the dome camera themselves are
typically small the lens size are limited,
Although some dome camera comes
with vari-focal lens but the size are
limited
14. Box Camera
When mounting to a wall or any vertical area
When viewing distance where a long lens is
required which would not fit inside a dome or
bullet camera
When extreme low light (moon light, or a very
far street light) are not a consideration
Requires a housing for weather proofing and
vandal proofing
When considering this camera accessories like
lens, housing, stand etc are to be considered
