SYSTEM LIMITATIONS
A fire alarm system can provide an early warning of a developing fire. But it does not assure protection against damage or
loss resulting from a fire.
The fire alarm system should be designed and installed in accordance with all relevant regulations and codes of practice.
To ensure maximum protection, the system should be regularly tested and inspected by qualified fire alarm installation
personnel. Inspection and testing should be carried out in accordance with the appropriate local standards.
TERMS and DEFINITIONS
Cable Form
- A connecting lead. Typically a length of flat cable with connectors at both ends. .
Serial Communication
- This may take the form of RS422, RS232, a FIBRE OPTIC Link or by TCP/IP. It provides
communications between the Panel and Repeaters.
Communications Port
- 5 Way Chameleon Connectors where interface flat cables are connected.
Device
- A detector, sounder, interface module or call-point connected to an Analogue Loop. .
Evacuation
- A system state where all sounders are activated simultaneously. Pressing SOUND ALARMS will generate a
global evacuate condition of the system. .
Fibre Optic Link
- A connection method for data that uses light instead of electrical signals. The connection is made using
fibre optic cables rather than copper electrical cables. Fibre optic signals can travel far greater distances than electrical
signals, with less risk of electromagnetic interference.
NVRAM
- Non-Volatile Random Access Memory. Any information stored in this memory will not be cleared when power is
removed from the system. It contains the LOG info, disablements and system status information.
PCB
- Printed Circuit Board. .
Front End or Chameleon Display - Should not be considered a repeater.
Everything displayed in the Panel “Front End”
is copied to the “Chameleon Display”.It is only possible to mirror a local Panel “Front End” with a Chameleon Display. Every
key press action is made as if the input was actually occurring on the connected panel “Front End”. This solution is normally
used on a single panel, not on networked panels.
CHAMELEON REPEATER - Acts as system repeater -
In a Chameleon Network, the CHAMELEON REPEATER is used
as a “System Repeater”. It works as an addressed networked panel (without loops) and has the ability to process and
register (log) all “system info”. Everything that is displayed in any networked system panel, with the exception of zonal LEDs,
will also be displayed on the Repeater Panel.
The System
- All wired networked panels (GEKKO, OCTO+, NODE+ or CHAMELEON REP).
