Installation Instructions Smartwired Switching System Installation and Operation Summary This Manual is focused on the needs of the Installing Contractor and the Operator. It assumes that the intent of the installation is to: 1 Provide a relay-based switching system for the lighting 2 Automate the operation of the lighting to comply with building energy codes such as ASHRAE 90.1 In the Smartwired Switching System, the switching platform consists of Relay Panels, Dataline Switches and a Dataline, which connects the parts into a small network. Automatic scheduling functions are provided by either a plug-in, 8-channel Network Clock or a Building Management System (BMS) Interface Module. An optional Photocell Control Module provides daylighting control of exterior lighting. Before starting, read the instructions in this summary. Full instructions detailing the installation and operation of Smartwired Switches, the Network Clock, BMS Interface Module and other optional automation devices follow.

The Watt Stopper will not warrant a system using a dataline that does not meet our specification. To avoid questions, use HDLW4(P) (plenum rated). Do not run the dataline in conduit or wiring trays with power wires. Do not connect the local datalines from two different panels.

Two points to remember: 1 Make sure your dataline conforms to The Watt Stopper specifications (see above right). If in doubt, use our dataline wire, HDLW4(P) (plenum rated). 2 The testing process ensures that all of the modules are working properly and that they are communicating with each other over the dataline. Step 2 Number and Document the Relays and Dataline Switches This is a key step. It helps clarify your intent and also provides a simple reference document for the next step. As shown in Figure 1 above, relay panels are numbered sequentially beginning with 01. Relays within a panel are numbered from 01 up to 48. By convention, relay 01-22 refers to panel 01, relay 22. Once you have confirmed that the relays are connected to the appropriate loads, record the description of the load controlled by each relay on the Smartwired Switching System Relay Schedule form shown in Figure 2 opposite. The dataline switches for each relay panel are also numbered sequentially beginning with 01-01 (panel 01, switch unit 01). A single switch unit may have one, two, four or eight buttons. Any switch button may be smartwired to any group of relays within a single panel. The relays controlled by each switch button are recorded on the Smartwired Switching System Dataline Switch Documentation form shown in Figure 3 opposite. 2
Step 3 Smartwire the Relays and Dataline Switches The actual linking of switches to relays is simple. It can be done using the process shown in Figure 4, or by using the programming function of the Network Clock (see instructions INHCLK-P). When the smartwiring is complete, confirm the operation of every switch button. With the wallplate removed and the switch s master button flipped open continue to flash; LEDs for the other buttons will stop flashing. LEDs for the relays currently controlled by that switch button will also begin to flash. 3 Select the relays to be controlled. In the relay panel, press the associated relay control button to add/delete that relay to/from the group. 4 Press the SMARTWIRE tab again. All LEDs will stop flashing. The selected switch button will now control the selected group of relays.

Network Clock The HCLK8SS Network Clock* provides scheduling for up to eight global channels (A-H). Each relay within a panel may be linked to one of these channels. In addition, each of these channels may be assigned any one of four different automation scenarios: Scenario 1: Scheduled ON/OFF (Interior Lighting) this scenario will turn on whenever the building is scheduled to be occupied and turn off when the building is scheduled to be unoccupied. As an option, the lights will blink to alert occupants five minutes before the scheduled off. Any dataline switch button controlling that relay will also begin to flash. Pressing the switch button will stop the flashing and a timed delay will be applied to the relay, over-riding the scheduled off. Data required by the Network Clock: A Occupancy time by day of week B Override time (in 10-minute increments, up to 4 hours) C Blink warn? Yes/No Scenario 2: Manual ON/Sched OFF (Interior Lighting Alternate) this scenario will not turn on until turned on by an occupant. During unoccupied periods, this scenario acts the same as Scenario 1 and the same data is required by the Network Clock. Scenario 3: Astro (Dark) ON/OFF (Exterior Lighting Security) this scenario will turn on when it is dark outside and turn off when it is light. Dark is defined by the user as a number of minutes before or after sunset. The Network Clock uses an astronomical * Only one Network Clock can be used per system. ** If a Photocell Control Module (HPCU8SS) is on the system, the Network Clock will request Footcandle data instead of Location and Dark data. Typical footcandle settings are: Security and Parking 2 to 20 fc, for Signage 20 to 200 fc. function to determine when sunset and sunrise occur. It does not compensate for rainy or overcast days. Data required by the Network Clock:** A Building location (nearest city/state or province) B Time in minutes before or after sunset that the lights should turn on (They will turn off symmetrically relative to sunrise example: 30 minutes after sunset / 30 minutes before sunrise) Scenario 4: Astro (Dark) ON/Sched OFF (Exterior Lighting Parking Lots/Signs) this scenario will turn on whenever it is dark outside and the building is occupied. It will turn off when the building is scheduled to be unoccupied. Data required by the Network Clock:** A Building location (nearest city/state or province) B Occupancy time by day of week C Time in minutes before or after sunset that the lights should turn on Installing and Commissioning the Network Clock Step 1 Define the Global Channel Scenarios The Smartwired Switching System Network Clock Automation Scenarios form provides a simple method for documenting the different global lighting scenarios and the operating data associated with each. Simply look at the different lighting loads in the building and group them by common function. (Figure 5) Step 2 Assign Relays to the Appropriate Channels With the above form in hand, it s easy to walk through the Smartwired Switching System Relay Schedule form (Figure 6) and select and document which channel a particular relay should follow. (If a relay doesn t follow a channel, it won t be automated.) Step 3 Smartwire Each Relay to its Associated Channel Smartwiring a relay to a channel is similar to smartwiring it to a switch. (Figure 7) Step 4 Install the Network Clock The HCLK8SS simply snaps onto the DIN rail in any panel and plugs into the global dataline as shown at right. Step 5 Enter the Network Clock Operating Data Refer to the Network Clock Installation Instructions INHCLK-S. Step 6 Test the Automatic Operation Set the Network Clock to two minutes before a scheduled action and confirm the operation. 4

BMS Interface Module The HBMS8SS Building Management System Interface Module provides an intelligent interface to other building systems, such as HVAC or Security. It is used instead of the Network Clock (HCLK8SS) to provide smart control scenarios for up to 8 global lighting groups (channels) in the network, and mounts to any panel s DIN rail. Only one BMS Interface Module or one Network Clock may be used in a system. Rather than schedule channels, as the Clock does, the BMS Interface accepts input from an external system to indicate the Occupied or Unoccupied status of a lighting group. For example, in some retail applications, it may be more convenient to turn on lighting when the security system is disabled, just as staff arrives. From a simple contact closure, the BMS Interface automatically applies the proven control scenarios selected for each channel. The same scenarios described for the Clock on page 4 apply to the BMS Interface Module. However, there are a few differences between the two units. Dark scenarios: Because the BMS Interface Module does not provide scheduling information, it has no Astronomical timeclock function. The Dark scenarios for exterior lighting automatically become available when an HPCU8SS Photocell Control Module is connected to the dataline. Egress Delay: Because the BMS Interface Module relies on another system for Occupied/Unoccupied information, it provides an egress delay. The user can set a time up to 4 hours after the channel becomes Unoccupied that allows occupants to exit the area safely before the lights are turned off. Contact Definition: Each channel has an associated Input Contact and Status Output Contact. The user can set parameters for these contacts based on interface requirements. Scenario 1: Scheduled ON/OFF Data required by the BMS Interface Module: A Override time delay (in 10-minute increments, up to 4 hours) B Blink Warn? Yes/No C Egress Time (0, 1, 10 240 minute in 10-minute increments) D Define Occupied for Input Contact (Occupied = Open or Closed contact) E Define Status Contact (Closed contact = Any ON, All ON, All OFF, Any OFF) Scenario 2: Manual ON/Sched OFF The BMS Interface Module requires the same data as in Scenario 1. Scenario 3: Dark ON/OFF For channels with this scenario, no input contact is required, since it depends completely on the exterior light level, provided by the Photocell Control Module. Data required by the BMS Interface Module: A Define Dark for each channel as any value from 2 to 200 fc. B Define Status Contact (Closed contact = Any ON, All ON, All OFF, Any OFF) Scenario 4: Dark ON/Scheduled OFF Data required by the BMS Interface Module: A Egress Time (0, 1, 10 240 minute in 10-minute increments) B Define Dark for each channel as any value from 2 to 200 fc. C Define Occupied for Input Contact (Occupied = Open or Closed contact) D Define Status Contact (Closed contact = Any ON, All ON, All OFF, Any OFF) Photocell Control Module The Photocell Control Module is another intelligent dataline module for the Smartwired switching system. It mounts on the DIN rail in any relay panel, and connects to the panel s dataline. A single photocell (HPSA), mounted on the building s roof, provides light level data to the unit. The Photocell Control Module compares the actual outdoor light level with the set point selected by the user for each of up to eight (8) channels in the system. It interacts automatically with either the HCLK8SS Network Clock, or the HBMS8SS BMS Interface Module, one of which must be present in the system. Set points for each channel are programmed through the Clock or BMS Interface Module, which provides scheduling, occupancy information and the smart scenarios that tell the relay panels how to respond to a Dark or Not Dark signal from the Photocell Control Module. An automatic deadband and 5-minute time delay avoid nuisance switching. An OPERATE/TEST switch on the unit makes it easy to simulate light levels for testing the system setup under different light level and occupied/unoccupied conditions. The unit provides quick visible indication of Dark or Not Dark status with bi-color LEDs for each channel. Panel Division 888-852-2778 INSS-SUM 020701
