Technical requirements:
1.All fire extinguishing signal cables are red (BOM number: 25030029) and black (BOM number: 25030073) cables with naked crimping single-wire cord end terminals (BOM number: 14170214). The red cable is positive and the black
cable is negative. The pneumatic switch, Warning signs, and fire alarm bell each has two wiring terminals that connect to two wires. The fire alarm bell is polarity insensitive. For details, see the diagram.
2.Connect a 10K terminal resistor to each of the last the fire alarm sounder and fire alarm horn/strobe in parallel.
3.Connect cables to the smoke detector and heat detector by referring to the diagram. Connect a 6.8 K terminal resistor to the last smoke and heat detectors in parallel.
4.Connect the emergency abort button and pneumatic switch to a 6.8 K terminal resistor in parallel, and to a 470 ohm resistor in serial.
5.Alarm signals are reported to the monitoring system over shielded straight-through network cables. The connection definitions are as follows: LOCAL FIRE, FIRE RELAY, and FAULT RELAY. The signal cables connect
contacts.
6.Attach cable labels to all cables connected to the extinguishant control panel, wiring terminals on electrical actuators, wiring terminals on pneumatic switches, and cables reserved for combined pre-fab. modules . See the label table for
the label content. Cable direction labels must be arranged neatly in the same direction. Cables must be bound neatly, with cable ties in the same direction. (Labels are printed on label paper with the BOM number 29041061, attached
on cable ties with the BOM number 21200708, and bound to corresponding cables.)
