4.2.8 Cable Planning
– LON-7000 Fiber Optic Networks
Cable length limitations, requirements for galvanic isolation, or environmental
electromagnetic interference may require network connection via a fiber-optic
connection.
The LRW-102 provides an easy solution for implementation of extending LonWorks
networks. The LRW-102 is completely transparent as far as the LonWorks protocol is
concerned, and does not require any additional addresses. The LRW-102 allows
implementation of fiber-optic networks in point-to-point, bus, or Class A redundant ring
topologies. The LRW-102 has a built-in support for redundant ring topology.
4.2.9 Cabling Planning
– ADR-7000 to TFP-3000 Fireman's Phone
Use two-wire cables (twisted-pair is recommended) 18 to 12 AWG (cross section of 0.8
to 3.3 mm
2
).
Two pairs from the ADR-7000 to the TFP-3000
– one pair for 24Vdc supply and one pair
for SLC communication.
4.2.10 Pre-Installation Planning
– Current Consumption and Battery
Capacity
Additional TPS-34A power supplies are required if one or more of the following
conditions is true:
The quiescence 24V current draw exceeds the control panel's power supply
limitations (0.5A for ADR-4004TSW)
The 24V current draw in alarm exceeds the control panel's power supply limitations
(4.0A for ADR-4004TSW)
There is a need for batteries in capacity that exceeds the control panel's power
supply limitations (12AH for ADR-4004TSW)
The voltage drop on the 24V lines exceeds allowed limitation (no more than 2V at
the furthest device, while still leaving sufficient voltage for the device to operate).
Calculate the power requirement for each ADR-7000 control panels to see whether
additional power supplies are needed. See "When are auxiliary power supplies
needed?" on page 86 for current draw calculations.
4.2.11 Pre-Installation Planning
– Activation Matrices
Plan the activation logic as specified by the consultant and local standards and
regulations.
4.2.12 Pre-Installation
– Releasing Planning
The size and quantity of extinguishing devices shall be calculated by authorized
personnel in accordance to the consultant's requirements and local regulations.
i
Note
Do not activate extinguishing devices by a Global Matrix (activated by logical
zones of devices physically connected to other control panels on the
network).
