RIO wired zone/output expander
A RIO wired zone/output expander provides 8 programmable zones and 4 outputs.
Note: A Power RIO can be fitted in place of a RIO.
The RIO requires 12 V d.c. (range 10.5 V to 16.0 V) and 40 mA. This can be supplied from
the control panel power supply or from a remote power supply if the distance causes a large
voltage drop on the cable.
Wiring
1. On a keypad, enter engineer mode before connecting the RIO.
2. Connect the RIO terminals as follows:
RIO terminals Connection point
+12 V control panel, keypad or remote power supply
–0 V or ground control panel, keypad or remote power supply
A A terminal of the previous module on the line or control panel if the RIO is the
first on the line
B B terminal of the previous module or control panel if the RIO is the first on the
line
Note: If the RIO is the last module on the line, connect a 680 Ω EOL resistor across
the A and B terminals.
Configuration
To configure the RIO in the system, exit from engineer mode. If the message XX Mod
Added [<],[>] To View is displayed, the system has recognised the module. Press A or B to
confirm that the RIO has been added. If the message is not displayed or the RIO is not on
the list of added modules, then it is not communicating with the control panel or has been set
to the same address as a RIO already connected to the system.
The flash rate of the red LED (LED 1) indicates module to panel communication status.
Flash rate (secs) Meaning
0.1 on / 0.9 off Normal communications
Off No d.c. supply
1.5 on / 1.5 off RIO has not been configured into system
0.2 on / 0.2 off RIO has lost communication with system
0.9 on / 0.1 off Very poor communications
Zones
The RIO has eight programmable zones that default to INTRUDER. Each zone is Double
Balance monitored with a 1 kΩ resistor in series with the zone detector and a 1 kΩ (1%)
resistor in parallel across the detector switch. The change to 2 kΩ (1%) resistance registers
the zone as open/alarm.
