General Information

The SMRT-100 consists of a factory installed low-voltage 5” high-resolution color touchscreen display, mounted on the front panel of the walk-in beside the door, a power/device wiring base installed in a weather proof non-metallic box on top of the walk-in, and a single combination sensor for measuring both temperature and %RH inside the walk-in.

With connection of a second sensor, the SMRT-100 can continuously monitor and display information for up to two separate rooms simultaneously.

The system may be enhanced by adding an optional SmartRite low-voltage pushbutton light switch installed on the same front panel as the SMRT-100, inside or outside of the walk-in room(s), and an optional SmartRite panic pushbutton installed inside the walk-in to activate an alarm in case of entrapment or other operator emergency.

The SMRT-100 also has the capability to use an optional interior mounted low-voltage motion sensor to control the lights, and/or an optional magnetic door switch to turn the lights on and/or automatically turn the evaporator coil blower fans off at entry.

The SMRT-100 has the capability for multi-way light switching from multiple door locations with the use of the low-voltage SmartRite switches (no 3 or 4-way required) and can modulate door jamb and view-port window heat as a percentage of time-on and time-off to save energy.

The SMRT-100 is set to “English” as the default language. If “Spanish“ is the preferred language, it may be selected from the Main Menu->Select Language setting.

To access the settings menu:

touch the “Menu” button at the lower left of the display. You will be prompted for a password;

enter the default password: 1 2 3 4

If the password is correct, you will have access to the Main Menu Settings.

Field Connection

Initial Wiring

Locate the conduit wiring stubs that protrude from the top of the door panel with the SMRT-100 display, switch (if applicable) and panic button (if applicable) installed. These stubs contain the 2, 3 or 4-conductor low voltage cable use to connect the devices to the power base. Mark and drill the ceiling panel(s) that sit on top of the door panel for the conduit stubs to pass through for access on top of the ceiling panel.

The Temperature and RH sensor should be mounted on the wall behind and to the left of the evaporator coil. They are each provided with 30’ of lead wire for connection to the Power Base. The sensor housing may be adhered to the wall using double-sided adhesive tape or by using a plastic wire tie with screw mounting hole, and the lead wires may be routed along the ceiling for exit through the top corner of the doorway, or lead wires may be routed through a small ¼” diameter hole drilled through the ceiling panel and sealed with RTV Silicone sealant. Sensor leads should be routed to the non-metallic Power Base enclosure just as for the device leads.

Power Base Mounting

On INDOOR walk-ins only, locate the SmartRite Power Base module with non-metallic weatherproof enclosure on the roof of the walk-in in a readily accessible location and as near as possible to the conduit wiring stubs with the low voltage cables. On OUTDOOR walk-ins with a membrane roof cap, locate the Power Base module and enclosure at the top of the exterior wall with closest accessibility to the wiring stubs and low voltage cables Each cable should be routed across the top of the ceiling panel and to the Power Base enclosure for connection to the Power Base.

Drill three each 7/8” diameter holes through the side of the non-metallic Power Base enclosure – one for device and sensor wiring, one for power wiring and one for light wiring. Install a ½” conduit size membrane cable seal fitting where the device cables will pass through and into the enclosure. ½” conduit fittings and associated conduit are to be installed from the power supply and light wiring stub as applicable. Once the device cables are routed and secured with adequate slack to prevent damage and are inserted through the fitting and into the enclosure, components are ready to be wired to the Power Base.

Power Base Wiring

Warning

To avoid damaging the electronic boards, ALWAYS put the TFT in Sleep Mode after disconnecting the power from the coldroom because the system has a back-up battery connected to the display module wich provide power to the base module, panic and external switches.see Sleep Mode Section
In Sleep mode battery is disconnected from the base module.To reconnect the back-up battery just plug the main power to the system.(see Sleep Mode)

TFT Display

Connect the 4-conductor low voltage color-coded cable (r-red, gr- green, w- white, bk-black) from the SMRT-100 TFT display to the corresponding color-coded terminals marked “DISPLAY”, terminals 60, 59, 58 and 57 (see Power Base Wiring).

Temperature and RH Sensor Wiring

Connect the 4-conductor low voltage color-coded lead (r-red, gr- green, w- white, bk-black) from the Temperature and RH Sensor to the corresponding color-coded terminals marked “SENSOR1”, terminals 56, 55, 54 and 53 (see Power Base Wiring)

Note

Up to two rooms may be monitored with the use of a second sensor mounted in the second room and connected to terminals marked “SENSOR2”, terminals 52, 51, 50 and 49 (see Power Base Wiring).

Door Switch

A low-voltage (DO NOT USE LINE VOLTAGE) magnetic door switch, supplied with the SmartRite Monitor/ Alarm, may also be connected where door activated lighting and evaporator fan control is desired, or where door-open monitoring/alarm is desired. The door switch is supplied with low voltage leads that must be routed through the ceiling as previously described for the temperature sensor and device wiring cables back to the Power Base on top of the ceiling. Connect the 2-conductor low voltage color-coded cable (w-white, bk-black) from the door switch to the corresponding terminals marked “DSw1”, terminals 48, and 47 (see Power Base Wiring).

Note

up to two doors may be monitored with the use of a second magnetic switch mounted on the second door and connected to terminals marked “DSw2”, terminals 46 and 45 (see Power Base Wiring).

External Light Switch (if applicable)

Connect the 3-conductor low voltage color-coded cable (r-red, w- white, bk-black) from the external SmartRite push button light switch to the corresponding color-coded terminals marked “ELgt”, terminals 25, 24 and 23 (see Power Base Wiring).

Note

Up to three individual SmartRite light switches may be connected to the Power Base for control of lights from any of three rooms (R1, R2 and R3 - see Power Base Wiring).

Panic Switch (if applicable)

Connect the 4-conductor low voltage color-coded cable (r-red, gr- green, w- white, bk-black) from the Panic push button switch to the corresponding color-coded terminals marked “PANIC”, terminals 32, 31, 30 and 29 (see Power Base Wiring)

Note

Up to three individual SmartRite panic switches may be connected to the Power Base for panic alarm activation from any of three rooms (R1, R2 and R3 - see Power Base Wiring).

Motion Switch (if applicable)

A low-voltage (DO NOT USE LINE VOLTAGE) motion detector, available as an option with the SmartRite Monitor/ Alarm, may also be connected where motion sensing lighting control is desired. The motion detector is supplied with low voltage leads that must be routed through the ceiling as previously described for the temperature sensor and device wiring cables back to the Power Base on top of the ceiling. Connect the 3-conductor low voltage color-coded cable (r-red, gr- green, bk-black) from the motion detector to the corresponding color-coded terminals marked “MOT”, terminals 28, 27, and 26 (see Power Base Wiring).

Note

Up to three individual motion detector switches may be connected to the Power Base for motion activation of all lighting from any of three rooms (R1, R2 and R3 - see Power Base Wiring).

Light Wiring

Connect the wiring from the room lights (field-installed, wiring and conduit from lights run by field electrician) to the Power Base terminals marked “LIGHT”, terminals 6 (*BK-LGT), 7 (WH-N) and 8(GR-G) see Power Base Wiring). *Please note that this must not be a switched leg, but must be direct from the line side of the light fixture wiring).

Power Wiring

Connect the 120VAC power wiring from a 15 Amp overcurrent protected supply circuit directly to the Power Base terminals marked “POWER”, terminals 1 (BK-L), 2 (WH-N) and 3(GR-G) (see Power Base Wiring).
