3.6.
LED
Light emitting diodes (LED) create light.
3.7.
Loop
The physical connection (through plugs JLD1, JLR1, JLD2, JLR2) of the fire loop module (AFM), to
which the detectors are connected. Outcomes can be configured independently of the loop, to which a
detector is connected. Each fire loop module has 4 terminals for altogether 2 fire detector loops (loop
1 with "drive" and "return" and loop 2 with "drive" and "return").
3.8.
Illuminated fields
Illuminated fields are provided on all main panels. Some are above the keys or located next to the
LEDs they are assigned to. They have a symbol or are labelled. The illuminated fields can light up in
various colours (red, green, yellow) depending on the situation. Their brightness can be adjusted
(daytime/night time operation). Fires or faults always light up with the full brightness on first
occurrence until they have been accepted (daytime operation with dimmed display)!
3.9.
Power supply
There is a mains and an emergency power supply. If one fails, the AFMS reports a fault. If the mains
power fails, the AFMS switches to emergency power. If both power supplies fail, the AFMS switches to
accumulator emergency operation until the accumulator has run down. Then the system switches off
(protection against full discharge for the accumulator(s)).
3.10.
Loops
Up to 16 conventional fire detectors can content a conventional loop in parallel. In the last fire detector
of a loop, a termination resistor of 3k
Ω
(+/-10%) must be fitted. With non-addressable fire detectors,
which can only by used by the FMS3000, a fires can only be detected in one loop and not in one
detector.
Up to 127 addressable fire detectors (better sensors) can be present in an addressable loop. There is
no termination resistance or "EOL device" needed. All detectors are connected in parallel to one cable
and each sensor can be only identified through HOCHIKI’s ESP telegram. All ESP sensors must be
programmed with a programmer (TCH-B100 [old]/TCH-B200
[new]
) or the relevant address is set on
site by using the dip switches on the sensor itself (this applies to some CHQ modules). The maximum
possible loop current is limited to 400mA. Any loop current is monitored by the existing energy
management system to keep any loop current as low as possible.
So that data can be transmitted
over long distances, the loop current is kept as low as possible by the ESP-supported special energy
management (keywords: “line loss”, “voltage drop on cables” and “line load”).
3.11.
Loop name
A conventional loop can be given a name in the configuration. This can describe the location of the
detectors connected to the loop. In an addressable system, the detectors possess a clear detector text
(and its group/fire zone), such as e.g. "Steering Gear Room 125 Aft" and the fire zone "Engine Room
Aft" and its address 38.
