The en-Gauge en-Vision Module (EVM) is the central element of the en-Gauge fire extinguisher monitoring system. When combined with an en-Gauge enabled pressure gauge it allows a portable fire extinguisher to become a fully supervised component of a monitored alarm system.
The EVM works in conjunction with an en-Gauge enabled fire extinguisher pressure gauge. The gauge has integral electronics providing extinguisher removal and pressure status signals to the EVM via a proprietary tether. The tether has a quick-disconnect type connector at the gauge end that is designed to break away from the extinguisher once the extinguisher has been removed from its designated location.
The EVM delivers the fire extinguisher status information both locally and remotely. The EVM annunciates any extinguisher status change (extinguisher alert or extinguisher trouble) locally through the use of Light Emitting Diodes (LEDs) located on the faceplate of the unit and through the use of an integral sounder.
The EVM can send an extinguisher alert or extinguisher trouble signal to other monitoring systems through the use of two form "C" relay outputs. The first relay output is designated the extinguisher alert output. This relay will change state if an extinguisher is removed from its designated location. The second relay output is designated the extinguisher trouble output. This relay will change state if the EVM senses that the extinguisher has had a pressure loss below a safe operational level, has had an obstruction continuously blocking access, or the unit's power source has dropped below a normal operational level. Both EVM output relays provide normally open or normally closed contacts.
The EVM can be powered via two 3 volt lithium batteries or from an external 12-24VDC power source. The EVM monitors its power source and will generate a unique trouble signal when the power level falls below a safe operating level.
