General
The Velocity MMP system network has the facility to monitor, indicate and control the functions of a fire alarm
installation, thus allowing signals to be distributed around a large site. The network will accommodate up to 64
nodes. The network uses RS485 data communication and a total network cable length of up to 10km is possible. All
panels will continue to function in stand-alone mode, even if the network fails. On a Velocity MMP running in a
network, all events are reported at all panels and all panels are able to remotely program other MMP panels sitting
on the network. Operation of outputs over the network is determined by the programmed cause & effects. Any
input on the network can be programmed to operate any output.
Installation
1. Ensure that the installation area is free from any cables or wires that may get caught, and that there is enough
space on the DIN rail to mount the module. Also ensure that the DIN clip underneath the module is in the open
position.
2. Place the module onto the DIN rail, hooking the metal earth clip underneath onto the rail first.
3. Once the earth clip is hooked, push the bottom of the module onto the rail so that the module sits flat.
4. Push the plastic DIN clip (located at the bottom of the module) upwards to lock and secure the module into
position.
VL-NWM [NETWORK MODULE] Installation Instructions
ATTENTION: THE PANEL MUST BE POWERED DOWN, AND DISCONNECTED FROM THE BATTERIES BEFORE
INSTALLING OR REMOVING ANY MODULES.

5. Once the module is secured to the DIN rail, simply connect the supplied CAT5E cable to the module’s RJ45 port.
6. Connect the other end of CAT5E cable to the nearest unoccupied RJ45 port on the termination PCB.
TRM R 45 Port Address Designation
Each RJ45 port on the Velocity termination has its own unique port address. This port address is important to keep
note of as it is displayed on Alarm Trouble messages and is used when configuring or setting up cause and effects on
the panel (See Velocity MMP operation manual GLT-261-7-2).
Securing the modules
The modules are designed to clip together to make them more secure. In addition, the MMP panel is supplied with
Din rail stoppers. These should be fitted before the first module, and after the last module on each rail.
Before Powering the Panel On
1. To prevent the risk of a spark, do not connect the batteries. Only connect the batteries after powering on the
system from its main AC supply.
2. Check that all external field wiring is clear from any open, shorts and ground faults.
3. Check that all the modules have been installed properly, with correct connections and placement
4. Check that all switches and jumper links are at their correct settings.
5. Check that all interconnection cables are plugged in properly, and that they are secure.
6. Check that the AC power wiring is correct.
7. Ensure that the panel chassis has been correctly earth grounded (See NFPA 70).
Before powering on from the main AC supply, make sure that the front panel door is closed

Power on Procedure
1. After the above has been completed, turn the panel on (Via AC Only). The panel will follow the same power up
sequence described in initial power up section above
2. The panel will now display one of the following messages
Message
Meaning
Pane
l has not detected any
modules fitted during its power
up check.
Power down the panel and check
that the expected modules are
fitted, and that all module cables
are correctly inserted.
Note that the panel will need at
least one module fitted to run.
The panel has detected a new
module added to a port that was
previously empty.
This is the usual message seen
the first time a panel is
configured
The panel has detected a
different type of module fitted to
a port that was previously
occupied.
The panel has detected a module
fitted to a port that is the same
type, but it`s serial number has
changed.
This could happen if a loop
module was swapped with
another one, for example.
The panel has detected no
module fitted to a port that was
previously occupied.

The panel has detected no
module changes, so has powered
up and started running
1. Check that the module configuration is as expected using the 

 to navigate the through the port
numbers. Press the 

2. The new module is now configured into the panel and is ready for use.
3. Since the batteries are not connected, the panel will report them as removed, lighting the yellow “Trouble” LED,
intermittently sounding the trouble buzzer, and displaying battery removed message on the screen.
4. Connect the batteries, ensuring that the polarity is correct (Red wire = +ve) & (Black wire = -ve). Acknowledge
the trouble event via the display screen, and reset the panel to clear the battery fault.
5. The panel should now remain in the normal condition, and you can configure the panel as normal.

Wiring Recommendations
The Velocity network can support up to 64 panels
Front Unit Indications
LED Indication Description
Trouble (Yellow) Flashing yellow when a fault on the RS485 circuit is detected.
RS485 TX (Green) Flashing green when the RS485 is transmitting information.
RS485 RX (Green) Flashing green when the RS485 is receiving information.
Com. (Green) Pulses green to show communication between the module and the
motherboard.
NOTE:
It is recommended
to install the network in a
ring topology for
protection against open
circuit and short circuit
faults.
RECOMMENDED CABLE: Belden type UL
