Advanced ExGo Relay Output Card | Expansion Module | Choice of 2-Way (RSI) or 8-Way (Control Panel)

FAQs

What is the difference between the EXP-007 and EXP-008 relay output cards?

The EXP-007 is a 2-way relay output card designed exclusively for use with ExGo Remote Status Indicator (RSI) panels, providing two individually programmable relay outputs. The EXP-008 is an 8-way relay output card compatible only with ExGo control panels (such as the EX-3001), offering eight individually programmable relay outputs for more complex system configurations. Both cards offer the same 1 Amp 30V AC/DC rating per relay, but the 8-way version provides significantly more expansion capability for larger installations requiring control of multiple ancillary devices.

How are the relay outputs programmed?

Each relay output is fully programmable through the host panel’s onboard keypad interface, with each output configurable for any output function allowed within the ExGo control panel’s programming parameters. This includes functions such as ventilation control, door releases, warning beacons, extractor fans, and other building management system interfaces. The programming process is straightforward and does not require external configuration tools, making commissioning quick and efficient.

Can multiple relay output cards be fitted to one panel?

No, only one relay output card can be fitted to each ExGo control panel or Remote Status Indicator. This limitation ensures proper power supply management and prevents potential conflicts in relay addressing. If more than 8 relay outputs are required for a system, additional relay modules would need to be sourced externally or multiple panels would need to be deployed as part of a networked system configuration.

What is meant by “volt free clean contact outputs”?

Volt free clean contact outputs are relay contacts that are electrically isolated from the control panel’s internal circuitry, meaning they carry no voltage of their own. This allows the contacts to safely switch circuits at different voltages (up to 30V AC/DC, 1 Amp maximum) without risk of electrical interference between the control panel and the connected equipment. This universal compatibility makes the relay outputs suitable for interfacing with a wide variety of building management systems, ventilation equipment, and other ancillary devices regardless of their operating voltage.

What does the “fail safe setup” option mean?

The fail safe setup option allows relay contacts to be inverted so that the controlled equipment defaults to a safe state in the event of power loss or system failure. For example, in normal configuration a relay might be energised to keep a door locked, but in fail safe mode the relay would be de-energised when the door should be locked, ensuring automatic unlocking if power is lost. The 8-way card provides 2 changeover contacts plus 6 normally open contacts which can be inverted, giving flexibility to configure each output for standard or fail-safe operation as required by the specific application.

How much power does the relay output card consume?

The relay output card draws its 24V DC power supply directly from the host panel’s motherboard and consumes a maximum of 65mA when all relays are energised simultaneously. This modest power requirement ensures the card can be powered from the panel’s existing power supply without requiring additional external power sources or upgrades to the panel’s battery backup capacity, simplifying installation and maintaining system reliability.

Can the relay output cards be ordered factory-fitted?

Yes, both relay output cards are available as factory-fitted options by adding the suffix “F” to the order code (EXP-007F or EXP-008F). Factory-fitted cards are pre-installed and tested by Advanced before the panel is shipped, ensuring proper installation and saving installation time on site. Alternatively, the cards can be ordered separately and field-installed using the mounting pillars provided on the panel’s back box, which is useful for retrofitting additional outputs to existing installations.

What typical applications would use the relay output cards?

The relay output cards are ideal for controlling ancillary equipment associated with gas extinguishing systems. Common applications include activating ventilation shut-off dampers, triggering warning beacons or sirens outside protected areas, releasing electromagnetic door locks to ensure clear evacuation routes, controlling extractor fans for post-discharge ventilation, interfacing with building management systems (BMS) for status monitoring, activating sequential startup of equipment, and switching auxiliary power supplies. The programmable nature of each output allows installers to create sophisticated cause-and-effect logic tailored to specific site protection requirements.
