Output module AM01-E
The output module has eight relays, three switched 24V outputs and one input for an external button.
To the outputs can be connected, for example, a machine alarm system, a VDR, fault and common
status displays, sirens, an automatic general alarm system, fire doors and/or flashing lights. Max. 2
output modules can be connected to the AFMS. The BUS address is set with a rotary switch on the
device. The configuration on the SD card must (as with all modules) correspond to the number of
assemblies being used.
A microcontroller controls the relays, the 24V outputs, the button input and communicates with the
master. On a command from the master, the output module switches its outputs. The rules for the
switching of these outputs are set in the configuration (NO, NC or alternating).
1.7.
Fire loop module AFM01-E
Addressable fire detectors are connected to the fire loop module (AFM). The fire detectors are
addressed through a BUS. A fire loop module (AFM) contains two loops. Up to 127 detectors can be
connected to one single loop. Up to four fire loop modules (AFM) can be used in one AFMS. This
gives a maximum count of 1016 sensors.
The currently valid regulations for the maximum permissible number of fire detectors in a fire zone, an
area, and the necessity for the use of short circuit isolators at the transition into different fire zones, or
transitions from deck to deck are to be observed!
Each loop consists of two equivalent connection pairs (Drive & Return). A three-core wire is connected
to connectors. The data transmission and electricity supply of the fire detectors is run through this
wire. All fire detectors are parallel connected to this wire. The detector loops are monitored for short
circuit, cable breakage and earth connection, so the live wires and the grounding wire can be switched
individually through a microcont further hardware. Due to the fact, that only one power input
and only one metal housing exists, an earth connection cannot be measured individually or displayed.
So all given earth fault events are only module based earth faults.
In order to ensure safe starting of the fire detectors, the outputs can be started slowly by a soft start
voltage.
For each loop, there is a modulator and a demodulator for data transmission on the fire loop module
(AFM) present.
Data transmission itself is according to ESP from HOCHIKI with 8Vss and 1200Baud.
The module also contains, in addition to the connections for the fire detectors, 8 potential-free outputs,
which can be configured as required for fire or fault. Two microcontrollers control and monitor the
loops, their outputs and communicate with the internal BUS.
1.8.
Fire loop module FM01-E
Only non-addressable (conventional) fire detectors are connected to the fire loop module (FM). Up to
16 conventional detectors can be connected in parallel to one loop. Up to eight loops can be
connected to one module. Up to 4 fire loop modules (FM) can be used in an AFMS (16*8*4 = 512
conventional detectors). The BUS address is also set with a rotary switch on the module itself. The
configuration must correspond to the number of assembled units (see above).
