installation instructions
introduction
The IMS-4821 humidity sensor is designed to connect to the IMS-4000 Host or Node and monitor indoor humidity. The
electrical connection between the sensor and IMS-4000 is made via RJ-45 patch cable (not included). The sensor may be
mounted either on a wall or to a single-gang electrical box.

(1) IMS-4821 Humidity sensor
(2) Plastic drywall anchors
(2) #6 Metal tapping screws
(1) 1/16" hex key
Cabling
The humidity sensor connects to the IMS-4000 Host or Node via an RJ-45 cable (e.g. CAT5 cable). The connection from the
sensor to the Host or Node can utilize your existing network wiring infrastructure. For example, the sensor may be installed
in another room or another floor. Connect the sensor to your structured wiring network via an RJ-45 jack. At the other end,
connect a patch cable from your structured wiring patch panel directly to the Host or Node environment input.
Caution: The IMS sensors are not TCP/IP devices and therefore should not be connected directly to any wiring
infrastructure that is connected to network equipment such as a hub, router, or switch. Sensors use RJ-45 plugs
and cables similar to those used with Ethernet devices.
Mounting
The humidity sensor can be mounted directly on a surface or attached to a single-gang electrical box. Consideration should
be given to cable routing before attaching the sensor to the wall. Will the cable go through the wall (cable hidden) or will
it run down the wall (cable visible)? Once this has been determined, run the cable to the location where the sensor will be
installed.
electrical box installation
Bring the RJ-45 cable through the electrical box. Remove the sensor cover by turning the two hex screws on the bottom of
the sensor housing clockwise. Bring the cable through the back of the sensor and connect the cable to the jack as shown in
Figure 1. Attach the sensor to the electrical box using the appropriate screws. Secure the sensor cover by turning the two hex
screws on the bottom of the cover counterclockwise.
