This page shows examples of custom alarms and accessories for Class 1, Division Hazardous Locations. The alarm still complies with all the requirements of our certifications. Generally to create a custom Hazloc alarm, the electronics cannot be modified, only the circuit board programming, and the external physical configuration such as the mounting. In addition, we are permitted to modify the type of simple device connected to the electronics enclosure. This is an advantage of the Intrinsically Safe approach to for creating alarms for Hazardous Locations: there is more flexibility allowed since the safety comes from the circuit design – not the enclosure.
Low level drum alarm for the small ¾ inch bung of drums. This uses our miniature stainless float switch with 0.60 S.G. Notice the float switch is concealed inside a stainless guard protecting to protect the float switch.
Intrinsically safe and meets UL913. This is essentially the same product the drum alarm to detect high liquid level, the IS-DHK-SS but this one was made longer to suit a 55 gallon drum. (therefore we call it IS-DLK-SS-55G)
Mot commonly customers prefer to mount this in the ¾” drum bung but is this case we provided the 2″NPS mount.
Intrinsically Safe level alarm with a 1 inch NPT bushing to mount it. There is no need for a grounding lug since the bushing makes electrical contact with the tank.

Intrinsically Safe level alarm for an IBC tank. Basically one of our tank alarms but with our IBC mount. Easily adjusts to the level an operator wants by loosening a thumbscrew. Can touch the bottom of the tank without damage to the float switch because the float is protected inside a stainless steel float guard. Polypropylene black cap with Polyethylene drum Plug 2″ NPS. Santoprene gasket to seal IBC cap to the IBC.
Toggle clamp for mounting alarms on tanker trucks. The clamp quicly clamps to the side of a manhole to secure the liquid level alarm.
BUNA float switch has a very light 0.50 Specific Gravity for extremely very light hydrocarbons if required. (our mini stainless float switch is 0.60 S.G. by comparison)

A stainless drum alarm with suction pipe – our model DHP-SS. This is a very common configuration for plastic drumalarms but uncommon for metal drums.
This example of a custom alarm for hazardous location is a “low headroom” tank alarm. (base model IS-T-SS) It had to fit in a small space over the tank so we mounted the electronics enclosure at a 90º angle. There is an adjustable rim-mount bracket to adjust the depth in the tank. The LED is pointed horizontally which is different from our usual vertical mounting. However in this case it would be pointed straight at the operators. This unit is the first to use a 316 stainless steel grounding lug. Previously we used 304 stainless and found that there was some corrosion. A pilot unit run along with the order was subjected to a 3-day salt fog test and showed no corrosion.
