Connectivity Examples
When operated under XP95 or Discovery Protocols, EN54-13 type 2 devices can be connected. In case EN54-13 type 1 devices need to be connected they must be installed directly next to this module, with no transmission path according to EN 54-13.
LED Status Indicator
| RLY | Continuous Red | Relay Active |
| Continuous Yellow | Fault | |
| POLL/ ISO |
Flashing Green | Device Polled |
| Continuous Yellow | Isolator Active | |
| IP | Continuous Red | Input Active |
| Continuous Yellow | Input Fault |
Note: Not all LEDs can be on simultaneously.
Commissioning
The installation must conform to BS5839–1 (or applicable local codes).
Maintainence
Removal of the external cover must be carried out using a at screwdriver or similar tool.
Caution
Unit damage. No electrical supply greater than 50V ac rms or 75V dc should be connected to any terminal of this Input/Output Unit.
Note: For compliance with Electrical Safety Standards the sources switched by the output relays must be limited to a 71V transient over-voltage condition.
Contact Apollo for more information.
Troubleshooting
Before investigating individual units for faults, it is important to check that the system wiring is fault free. Earth faults on data loops or interface zone wiring may cause communication errors. Many fault conditions are the result of simple wiring errors. Check all connections to the unit.
| Problem | Possible Cause |
| No response or missing | Incorrect address setting Incorrect loop wiring |
| Incorrect address setting Incorrect loop wiring |
Incorrect input wiring Incorrect wiring Control panel has incorrect cause and effect programming |
| Relay energised continuously | Incorrect loop wiring Incorrect address setting |
| Analogue value unstable | Dual address Loop data fault, data corruption |
| Constant Alarm | Incorrect wiring Incorrect end-of-line resistor tted Incompatible control panel software |
| Isolator LED on | Short-circuit on loop wiring Wiring reverse polarity Too many devices between isolators |
