EXIGO Industrial Ex Access Panel
- Network access panel for explosive atmospheres
- Ex m b ib e IIC T4 Gb
- DSP for acoustic signal processing
- IP networking and power over Flowire technology
- One programmable button with individual label and status indicators
- Optional button protection covers
- Indicators for power, call and fault
- For single or dual systems (A and B systems)
The EAPFX-1 is a rugged access panel, developed for harsh offshore environments and hazardous areas. The antistatic plastic housing withstands corrosion from the most common corrosive gases and compounds found in this type of environment. The access panel features one fully programmable button, which can be used to manually initiate fire alarms, gas alarms or any other action in the Exigo system. The access panel is equipped with indicators to show the status of the power supply, call activity and whether a fault is present in the system. The access panel’s button features two independent status indicators, which shows the status of the button’s function. The access panel is fully digital, and connects to the Exigo system over a single-pair cable. The access panel is fully monitored to ensure detection of any fault which may compromise the system’s functionality.

| 2 | Molded electronics |
| 3 | Flowire connections |
Flowire Connection
The EAPFX-1 features two Flowire connectors. Power and signal redundancy can be achieved by utilizing both Flowire connectors in an A-B system configuration.
Do not connect more than 9 Ex Products to each central Flowire Converter
Only use one of the Flowire connectors on each Ex product for each central Flowire Converter
Load sharing power supply must be used for redundant cabling solutions.
Consult with Zenitel before implementing this type of solution.
Central connection
The central rack must contain
- A server
- A Flowire Converter (FCDC2)
- A 24V Power Supply Unit (PSU)
In order to connect several Ex Products to one central FCDC-2, you also need a terminal block.
Only use 24VDC power supplies sold or recommended by Zenitel for Ex products
Grounding
To establish explosion-proof protection, it is vital that
the grounding of the panel is done according to the following instructions.
All ground and shield cables from the central rack must be terminated on the ground sheet inside the main housing. Grounding must be done according to IEC 60079-17.
The apparatus does not withstand the electrical strength test with 2 x Um 250V r.m.s. to earth according to clause 6.3.13 of IEC/EN 60079-11: 2011/2012, because the equipment has a connection to earth.
Cable insertion
Only cables certified for use in explosive atmospheres shall be used
Only Ex certified cable entries made from plastic shall be used.
The prescribed cable diameters and other guidelines for cable entries used shall be observed
The relevant mounting directives for the cable entries used shall be observed
When using cable entries with a degree of protection that differs from the IP protection of the
Ex Product (see Technical Specifications), the limiting IP protection level shall be adhered to.
When using cable entries with an ambient temperature range that differs from the ambient temperature
range of the panel or intercom (see Technical Specifications), the limiting temperature range shall be adhered to
When using cable entries with impact resistance that differs from the impact resistance of the panel
or intercom, the limiting impact resistance shall be adhered to
Cable entries must have ingress protection IP54 or higher
Cable entries must be approved according to IEC 60079-0:2007 or EN 60079-0:2009 or
later versions of one of these standards
In order to ensure the required minimum degree of protection, the cable entries must be tightened down securely.
Over-tightening can impair the degree of protection and damage the Ex Product
When tightening the cap nut of a cable entry, a suitable tool shall be used to prevent the gland from twisting
When using the Hummel M16 cable gland HSK-K-MZ-Ex included in the box, the following limiting factors apply
- Lowest temperature -20°C
- Impact resistance: 4J (low risk of mechanical danger)
