Room Alert Sensor Summary

A table showing the maximum number and type of external sensor ports on each Room Alert monitor. The numbers presented are a maximum, you can leave sensor ports empty ready for future use and expansion of your monitoring.

  Room Alert 3 Wi-Fi Room Alert 3E Room Alert 3S Room Alert 12S Room Alert 12SR Room Alert 32S
Max Digital Sensor Ports Digital sensor ports only support connecting digital sensors. Digital sensors measure within a range of values, like a temperature range. 1 1 1 3 3 8
Max Switch Sensor Ports Switch sensor ports only support connecting switch sensors. Switch sensors only measure one of two states, the normal state and the alarm state. Take the smoke sensor as an example, it has a normal state which indicates no significant smoke is present and an alarm state that indicates that a significant amount of smoke is present perhaps indicating a fire. 1 1 1 4 4 16
Max Analog Sensor Ports Analog sensors provide values as voltages between 0-5VDC. Common analog sensors include current loops and extreme high and low temperature sensors. The Room Alert 3 WiFi and Room Alert 3E do not support analog sensors, but you can buy the Digital Temperature & Analog Sensor to add support at the cost of one of your digital sensor ports. 0 0 0 1 1 2

Temperature Sensor Comparison

A guide to all of the temperature sensors available from Avtech including temperature range, accuracy and Room Alert compatibility.

The temperature sensors mostly use an RJ-11 digital connector to attach to your Room Alert monitor. If you would like more information about the various Avtech sensor connectors, please read the Guide to Avtech Software Sensor Types.

Flood Sensor Comparison

There are two types of flood sensor available for the Room Alert range of monitors.

Spot Flood Sensor

The spot flood sensor is able to detect water ingress in a single location. It is typically used either with a sink or a drip tray that concentrates water into a single central tray section where the spot flood sensor is located.

Spot sensors are very good at locating water in a single location but they are not very useful if you wish to detect water over a much larger area. That is where the rope flood sensor comes into its own.

The Spot Flood Sensor is available with a lead cable length of 7.5m only. The length of the lead cable is the distance you can place the water sensitive unit away from your Room Alert monitor.

Product Lead Cable Length SKU Room Alert Monitor Support
Spot Flood Sensor 7.5m RMA-FS2-SEN All Room Alert monitors

Rope Flood Sensor

The rope sensor is able to detect water ingress over a wide area by using a long water sensitive cable. The cable can be used to cover a wide area typically underneath a server room raised floor or inside the ceiling space above a server room.

Rope Flood Sensors are available with a water sensitive rope length of 2.4m or 7.5m. The length of the water sensitive rope determines how large the area you are able to monitor for water ingress. The longer the cable, the larger the surface area you can monitor.

Each Rope Flood Sensor has a 4.5m cable connecting the flood sensor to the Room Alert monitor. Therefore, you can place the water sensitive cable up to 4.5m away from your Room Alert monitor.

Product Lead Cable Length Water Sensitive Cable Length SKU Room Alert Monitor Support
2.4m Rope Flood Sensor 4.5m 2.4m RMA-F008-SEN All Room Alert monitors
7.3m Rope Flood Sensor 4.5m 7.3m RMA-F024-SEN All Room Alert monitors

External Sensor Length

Digital sensors have a maximum length of 100' or approximately 30m. AVTECH Software do not recommend splicing or cutting into existing wires to shorten or lengthen the provided cable.

You can extend the digital sensor cable by using RJ-11 cable with coupler. The simplest method is to purchase the length you require.
