RELAY FAIL-SAFE SETTING
From a safety perspective, any unknown situation must be considered potentially hazardous. When a stand-alone
gas detector is unable to detect gas, an unknown condition is created and precautions must be taken to prevent
personal injury or loss of life. This means that the device must be able to alert the end-user that it is no longer fully
operational. This safety function is made possible by the fault terminal. For more information about the fault terminal
and for instructions on how to wire your device, refer to the Connecting the Fault Terminal section of this manual.
Site specific circumstances may prevent the use of the fault terminal, leading to potentially dangerous situations
without end-user notification. In response, the OI-6000 provides a relay fail-safe setting to enhance the safety
protection provided when the fault terminal cannot be used.
The relay fail-safe setting reverses the behavior of the relays and allows a deactivated relay to serve as a warning
of a potentially hazardous event. In fail-safe mode, the relays are activated upon device start-up and deactivated
during alarm conditions and when the device is turned off. Some device failures, such as loss of power and firmware
corruption, will also deactivate the relay.
NOTICE
For maximum safety, the fault terminal MUST be used. A fail-safe relay will NOT notify the user of all potential
device failures. The fail-safe setting should ONLY be enabled to provide enhanced safety protection when the
fault terminal CANNOT be used.
The factory default settings on the OI-6000 for Relay 1 and Relay 2 fail-safe are No (Off).
