Protective Alarm Sensors and Protective Lighting
Protective Alarm Sensors

barriers.
Their purpose is to alert security personnel of attempted intrusion into
a building or compound.
Types of protective alarm systems:
Local alarm system
Auxiliary system

Protective Lighting
Protective lighting is lighting designed to illuminate outside approaches
to an area or facility. It helps deter intruders since a threat is more
likely to attack an asset.
Purpose of Protective Lighting
Provides sufficient illumination at night or during darkness.
Improves visibility, making intruders easier to detect.
Creates psychological fear in offenders.
Deters thieves, trespassers, and saboteurs.
General Characteristics
Inexpensive to maintain.
Reduces the need for many security forces.
Protects security forces by reducing surprise attacks.
Requires less intensity than regular working lights.
Types of Protective Lighting
1. Stationary Luminary (fixed lighting)
Glare projection type – produces bright white light focused on
intruders, making them visible but unable to see ahead.
Controlled lighting – focuses light on specific objects or areas
rather than the whole background.
2. Standby Lighting – provides continuous illumination in darkness; can
be turned on manually or automatically.
3. Movable Lighting – stationary or portable (e.g., searchlights), manually
operated and used as needed.
4. Emergency Lighting – activated during power failure, using generators
or batteries (e.g., stairwell lights during a fire).
