System Components
A system comprises of the following components:
1. A control unit, which processes all the alarm information from the detection points. Outputs are
provided to operate sounders, strobe and communication devices. Configuration information is
stored in EEPROM. The manual details the features of the control panels. Most features in the
PX panel range are common. The differences are shown in the table.

The diagram on the following page shows the bus peripheral connections.
2. User interaction with the system is via LCD keypad. There must be at least 1 keypad on a
system. There are several types of LCD keypad available, which are detailed later.
3. On the RX16i, QX32i, PX48i, PX80i and PX250i, up to 8 detectors may be connected directly to
the panel. Further detectors, up to the control panel limit, may be connected to the system
through concentrators on a 4-wire bus. Each concentrator provides 8 additional circuits.
4. Optional equipment includes;
1. A dialler/modem/Dual comm module
2. Output modules each with 8 programmable outputs
3. A serial module for connection of a printer or PC
4. Bus isolator
5. Access module
6. Data comms module for an Ethernet connection to a PC
7. Radio module
8. Audio module
