INTRINSICALLY SAFE ALARM IS-AB
1. CONNECT BATTERY
The battery pack connects with the JST connector. Only battery model
BT-IS may be used. Battery is Intrinsically Safe and may be changed
in the hazardous area. Refer to control drawing IS-001.
2. PROGRAM DESIRED MODE
•The modes available are selected using the DIP switches as follows:
3. OPERATION
•When there is a level alarm, the LED and buzzer will alternate. The front
button silences the buzzer. In the mode with switch #2 “ON”, the LED
will continue to flash until level is corrected. If switch #1 is “ON” the
buzzer will sound again after a 30 minute “snooze”.
•If the alarm is not acknowledged for 60 minutes, the alarm output
will be reduced to save battery power. After 60 minutes, all alarms
will be reduced to only 5 sec. every 30 seconds. This allows the
alarm to last for up to 600 hours (25 days) in this power-saving
mode.
4. OTHER POINTS
•Operating temperature is -40ºC to 60ºC. (-40ºF to 140ºF). Rated
for outdoor use.
•Very low temperatures will diminish the battery life. For example if
operating at -40º, the battery will be reduced by half. See website
for more detailed information.
•Low battery is indicated by an alarm with which has a rapid beeping
pattern for 5 seconds every 30 seconds.
•If there is a second sensor connected,(on LS2) it will have a slower
beeping/flashing pattern from the first sensor. (slow vs. fast pattern)

5. RELAY OUTPUT
•If your model includes a relay output, follow notes in “Control Drawing “IS-001” so the
remote device in the “safe” area does not introduce an unsafe voltage into the hazardous
area.
•The remote device must be connected through an Intrinsically Safe barrier. .
•Connect the output cable to the IS-AB using the cable with screw-lock connector provided.
6. EXAMPLE INSTALLATION
•Install a level switch associated with the IS-AB on a tank or drum by screwing the mounting thread of the level
probe into the tank or drum opening.
