SI-100IM (Main Alarm Unit)
When the power switch is ON, an AC / DC voltage according to an input
voltage and a bar graph according to a voltage level will be displayed. An
arrow on the side of the bar graph indicates a voltage range of the
products at its operational status.
Turn on the battery switch (back-up power) on the back of the product,
and spare power lamp will be extinguished and the device will enter into
a normal state. If you press the back-up power switch to find a spare
power status, the device will display a DC voltage and a charging voltage
will be displayed. When an alarm occurs, the power indication unit will
display the ID of the Alarm Unit. According to primary, secondary and
tertiary alarm set in the alarm, an alarm icon will be blinking. (An ID will
be displayed alternating if alarms occur in many places.) When an alarm
occurs, you can press the buzzer stop switch to mute the sound.
If you press the Return button when the alarm condition is released, the
alarm icon and all operations will turn into a normal status. Because
turning on the failure icon may be caused by failure of the Alarm Unit,
you need to check the Alarm Unit.
SI-100IA (Alarm Display Unit)
When the power is turned on, the device will display the product software
version (1.00.A) for 1 sec and an ID of the Unit from (01) to (12) seconds
for 4 seconds. Then, after 25 seconds of stabilization, a corresponding gas
density will be displayed. When the Power icon is turned on after flashing
during initial stabilization time (30 seconds), the device will enter into a
normal operation (If

is displayed and an alarm emits, the wiring in
the detection unit is defective or has bad connection. If the sensor is
defective, you need to have the device checked). If a gas leakage happens,
the gas concentration will go up according to the changes in a
corresponding gas concentration and a bar graph will be also pushed up
by a concentration. As a concentration rises, 1

alarm will be
generated according to an alarm setting value, thereby making a
corresponding signal output (12V, Dry Contact, 4-20mA). With the circuit
test switch, you can test a status of the product in normal concentration
state. When you press the test circuit for a second, the concentration bar
graph will go up, thus generating an alarm and an output like those from
gas reaction.(However, during the circuit test, an output of 4-20mA will
not be made). Gas alarm or circuit test can be return to the start with the
return switch. (Individual Return)
