Service and Maintenance
Visual Inspection
The Alarm Unit should be inspected annually:
•
Inspect the unit for signs of corrosion, pitting, and water damage.
•
Inspect the inside of the Junction Box(s) for signs of water accumulation and/or signs of corrosion.
•
Check internal wiring to ensure there are no loose or pinched wires and all connections are clean and
tight.
Condensation Prevention Packet
A moisture condensation packet should be installed in every explosion proof Junction Box. The moisture
condensation prevention packet will prevent the internal volume of the J-Box from condensing and accumulating
moisture due to day-night humidity changes. This packet provides a critical function and should be replaced
annually. Detcon’s PN is 960-202200-000.
CAUTION:
Explosion Hazard – DO NOT remove or replace lamps or plug-in modules unless power
has been disconnected or the area is free of ignitable concentrations.
CAUTION:
Explosion Hazard – DO NOT disconnect while the circuit is live or unless the area is free
of ignitable concentrations.
CAUTION:
Explosion Hazard – DO NOT connect or disconnect when energized.

Replacement of the battery pack
The Controller incorporates a ‘LOW BAT’ (low battery) fault message which will appear on the controllers
display for the associated alarm unit. This fault will appear when the battery voltage or the ‘state of charge’
drops below a preset threshold. Refer to the controller manual for more information.
NOTE
The safety approvals require removing the alarm unit to a non-hazardous area before
installing or changing out the batteries or battery pack.
1.
Remove the cover from the Junction-box.
2.
Unscrew battery bracket lid and swing the lid away from the battery pack.
3.
Remove the battery pack from the Junction-box and replace with new battery pack.

Swing the lid back over the battery pack and re-tighten screws in battery bracket lid.
5.
Replace the cover on the Junction-box.
CAUTION:
Explosion Hazard – Batteries must ONLY be changed in an area free of ignitable
concentrations.
CAUTION:
Explosion Hazard – Batteries must ONLY be recharged in an area free of ignitable
concentrations.
