Figure 9-3. Elements of a Fire Alarm System
Wire and conduit from the fire alarm system to the security system. It is required that the power
and communication lines not be placed in the same conduit.
Assignment of fire alarm input/output addresses. The fire alarm system sends a signal (fire alarm
system output) to each individual door controller in the event of a fire alarm signal.
Assignment of security system input/output addresses.
Termination of the fire alarm/security system interface on the fire alarm system.
Termination of the fire alarm/security system interface on the security system.
Programming of the fire alarm system to achieve door unlock signals in the event of a fire alarm
signal.
Programming of the security system to achieve door unlock signals in the event of a fire alarm
signal.
Door access control hardware all needs to be "home run" to a local junction box for ease of
troubleshooting and repair.
9-6.17
Intercom System. While not a requirement, site-specific factors may require
provision of an intercom or similar auxiliary communication system at entry portals (such
as motorized gates) to communicate with entering personnel from the Dispatch Center
or other location.
9-6.18
Lighting. While not an official part of ESS, lighting is an effective part of the
overall physical protection design. Lighting should be considered as a countermeasure
for protection of each critical asset. Coordination with the electrical/lighting engineer
needs to occur for placement of lighting to enhance viewing of CCTV systems, as
discussed in Chapter Four.
9-6.18.1 Lighting at guard check-points must be sufficient to clearly allow a guard to
verify the picture ID on access badges. Some installations may provide a fixed camera
at an automatically operated gate for both surveillance and verification of a visual
credential for access. In these cases, lighting must similarly be sufficient to allow
accurate verification of the picture ID.
