Figure 1: Typical Network Layout
The basic layout of the network is a single loop (see Figure 1). Each panel and annunciator has a
unique ID. There is no requirement that the IDs be sequential or that they start with 1. The master
panel can be any fire panel in the network. The panels work in a peer-to-peer fashion. This means
that each panel is responsible for the programming of the inputs connected to it. The master panel
does not control the network, but it is the central location for network information. Information is
exchanged over the network via two basic means: a) specific frames, which are from one panel to
another, and b) broadcast frames, which are from one panel to all others.
Notes:
1. For correct operation of the network, all panels and annunciators need to be loaded with
the same version of operating programs and with the same database. If changes are
made to the database, it is necessary that ALL panels and annunciators be reloaded.
2. When panels and annunciators are first installed, the panel ID must be entered into it
before loading the database.
The special functions of master panel are:
a) synchronize the clocks on the network by broadcasting the date and time at 3:30am every
day; this means that only the master panel of a network requires that its clock be calibrated;
b) maintain a network alarm list that includes all alarms, supervisory and trouble conditions
induced on any panel on the network;
c) transmit all signals from the network to a monitoring location.
Feature Operation
The following are the various types of frames that are sent on the network.
Commands & Restores
These specific frames are sent when a device in alarm requires operation of outputs at another
unit. These commands are for the bells, relays, control modules, device messages and LEDs.
When the device itself restores, the restore commands are sent right away so that the other panels
know that they can be reset. Anything operated stays latched until the Reset key is pressed.
Hotkey and Hotkey LED Operation
If a unit has its hotkey routing set for specific panels only, it sends Acknowledge, Reset, Signal
Silence and Second Stage Inhibit to these panels as specific frames. If hotkey routing is Global in
the database, these are sent as broadcast frames.
If a panel’s function keys are sent to other panels, those panels send commands to the panel to
have it turn on and off the hot key LEDs. This is so that there is indication that the key function has
become available. This causes the LEDs to continue flashing after the key is pressed until the
frame is received to turn off the LED.
Time/Date Change
This broadcast frame is sent by a panel or annunciator if the time or date is changed. The master
panel also sends both a date and time change frame at 3:30am every day to synchronize all the
clocks in the network.
Manual Switch Operation
If the state of any of the 16 software switches is changed manually at any panel, this change is
broadcast to all other panels. The software switches are a system resource.
Network Reboot
If a Network Reboot command is initiated at a panel, it is broadcast normally and then the panel
reboots itself. Upon receiving the Network Reboot command, a panel passes the command on to
the next panel and then reboots itself. This has the affect of causing all the panels to reboot
simultaneously.
