GIZMO ENGINEERING IS-AB Manual

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 BT-IS
2. PROGRAM DESIRED MODE
• The modes available are selected using the DIP switches as follows:
SWITCH
30 min. buzzer snooze alarm.
1
PB shuts off buzzer, but LED & relay stay on until
2
both level is corrected.
Auto reset of LED, buzzer and relay when level is
3
corrected.
Relay N.O.
4
Relay output delayed 15 mins.
5
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)
• Low battery is indicated by an alarm with which has a rapid beeping
pattern for 5 seconds every 30 seconds.
• 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.
• 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)
• If there is a cable connecting to the box,the sensor is N.C,. so there
will be an alarm and relay output if the cable becomes
disconnected.
ON
No buzzer snooze alarm.
Pressing button shuts off buzzer and LED, and resets
relay, regardless of level.
Manual reset: must push button after level is corrected to
reset LED and relay.
Relay N.C.
Relay output is immediate.
