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)

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.
