How to Read BMS Requirements Hidden in Floor Plan Notes Actual Floor Plan Note (Seen on Drawings)

December 29, 2025

INSTALL SPACE TEMPERATURE SENSOR, CARBON DIOXIDE SENSOR, AND HUMIDITY SENSOR WHERE SHOWN. ALL SENSORS SHALL HAVE VANDAL-RESISTANT COVER

 What This Single Note Really Means for a BMS Engineer
This is not just an installation instruction — it carries design, submittal, and site implications.
1. Multiple space sensors are required (Temp + CO₂ + Humidity)
2. Sensors are located in occupied / publicly accessible areas
3. Vandal-resistant cover is mandatory, not optional
4. Sensor selection must consider accuracy + protection

Simple Definition (Training / Site Friendly)
A vandal-resistant cover is a tamper-proof protective housing designed to safeguard HVAC control devices from physical damage, misuse, or unauthorized access.

Why Consultants Specify Vandal-Resistant Covers
1. Prevent occupants from changing setpoints
2. Protect sensors from physical damage
3. Restrict unauthorized access
4. Increase durability in public or harsh environments

Where This Requirement Commonly Applies
1. Schools & colleges
2. Hospitals & clinics
3. Airports & metro stations
4. Shopping malls
5. Public offices
6. Hotel corridors & lobbies
*Any place where occupants can physically reach the sensor.

Key Design Features to Verify
1. Lockable (key-based or Allen screw)
2. Transparent (sensor remains visible)
3. Ventilated (critical for accuracy)
4. Wall-mounted or device-mounted

One-Line for Control Submittal / Sensor Schedule
Space temperature, CO₂, and humidity sensors shall be provided with lockable, ventilated, vandal-resistant polycarbonate covers suitable for public areas.

Good BMS engineering starts with reading drawings correctly — not just wiring points. Small notes like this can save RFIs, rework, and client comments.
