16. Smoke is a device that System
Detector
 A smoke detector
detects smoke
 Smoke detectors are typically
housed in a disk-shaped plastic
enclosure about 6 inches in
diameter and 1 inch thick.

17. Sprinkler System
 A fire sprinkler system is an active fire
protection measure, consisting of a water
supply system, providing adequate pressure
and flow rate to a water distribution piping
system, onto which fire sprinklers are
connected.
 63 degree temperature
 Covers 6Mts .

18. Manual Call point
 It is an active fire protection device, usually
wall-mounted.
 when activated, initiates an alarm on a fire alarm system.
 the user activates the alarm by pulling the handle down,
which completes a circuit and locks the handle in the
activated position, sending an alarm to the fire alarm
control panel
 After operation, some fire alarm pull stations must be
restored to the ready position using a special tool or key in
order to deactivate the alarm sequence and return the
system to normal
