Figure 44 EEPROM Override
EXCEPTION -
If an EEPROM error occurs, then the Exception Code 04 (Slave
Device Failure) is returned.
NOTE -
By grounding the ALARM TEST input during the first 10 seconds of the 2
minute power-up cycle, the FL3102 will Disable the EEPROM Override and set
the Bit = 0, enabling the 8-position Dip-switch. The red and green LED’s will flash
simultaneously while the ALARM TEST input is grounded. The EEPROM
Override bit will be set to zero and the Dip Switch enabled when the red and
green LED’s flash alternately after approximately10 seconds, at which time the
ALARM TEST input can be released from ground.
7.7.9 Options
A read returns the status of the settings for the Detector Sensitivity, Relay Delay,
Relay Latching/Non-Latching and Relay Energized/Non-Energized features
either from the Options DIP-switch or the EEPROM depending on the setting of
the EEPROM Override bit listed above. A write command changes the settings
for the EEPROM only when the EEPROM Override bit is set.
EXCEPTION -
If an attempt to change the EEPROM Options is made while the
EEPROM Override bit is not set, then the unit shall return an Exception Code 03
(Illegal Data Value).
EXCEPTION –
If an EEPROM write error occurs, then the Exception Code 04
(Slave Device Failure) is returned.
These Functions are indicated on the Low Data Byte and the High Data Byte is
not used.
