Frequently Asked Questions - EME1A1-005 Black Box

What is the Black Box EME1A1-005 voltage sensor used for?

The EME1A1-005 is an AC voltage sensor that monitors the presence or absence of voltage from 50 to 250 VAC. It provides an Alarm or Normal indication and can be used with AlertWerks monitoring systems.

How does the EME1A1-005 get power?

The sensor is powered by the AlertWerks hub (e.g., EME102A or EME108A) via the RJ-45 connection. No external power supply is needed.

What is the maximum cable length between the sensor and the hub?

The maximum extension cable length is 1000 feet (304.8 meters) when using approved low-capacitance shielded cable or UTP.

Can I use multiple EME1A1-005 sensors with one hub?

Yes. You can connect up to two AC voltage sensors per EME102A ServSensor Junior, and up to eight per EME108A ServSensor or EME134A Expansion Hub.

Does the sensor support SNMP?

Yes, the voltage sensors include an SNMP interface for alarm/normal status. You can configure alerts via SNMP traps, e-mail, or SMS.

What type of cable is required for connection?

Use a UTP CAT5 cable with an RJ-45 jack to connect the sensor to the hub.

How do I configure the sensor for my application?

Configuration is done via the Web interface of the connected AlertWerks hub. You can set voltage thresholds and notification methods.

What does the Alarm/Normal indicator mean?

The indicator shows Alarm when voltage is outside the configured normal range (or absent), and Normal when voltage is present and within range.

Is the EME1A1-005 suitable for DC voltage monitoring?

No, the EME1A1-005 is specifically for AC voltage (50–250 VAC). For DC monitoring, use the model EME1D1-005 which is user-programmable from 0 to 250 VDC.

What maintenance does the sensor require?

The sensor is low-maintenance. Periodically check cable connections and ensure the hub is powered. Clean the sensor with a dry cloth if needed. No internal user-serviceable parts.
