SZ-IO Control Interface
PELV (Class 2: USA) Device
15 – 24 V
200 mA
Stanza
TM
Features
• Integrates a
Stanza
lighting control system with equipment
that has contact closure I/O, including:
- Occupant and vacancy sensors
- Motorized window treatments
- AV equipment
- Security systems
- Thermostats
• Provides five inputs and five outputs.
• Provides both normally open (NO) and normally closed
(NC) dry contacts.
• Using the inputs, contact closures outputs from other
equipment can operate
Stanza
devices to:
- Select scenes.
- Turn lights on or off.
• Using the outputs, other
Stanza
devices can:
- Trigger outputs to control other equipment.
- Provide status feedback to other equipment.
• Supports an external device drawing up to 100 mA. Note
that the power is supplied directly from the external low-
voltage PELV.
Mounting
1. Mount the interface directly on a wall, as shown in the
Mounting Diagram, using two #6 (M3) screws (not
included).
2. When mounting, provide sufficient space for the antenna
and connecting cables.
3. Mount in an accessible location for convenient access to
DIP switches, LEDs, and terminal blocks.
4. The unit cannot be mounted in a full metal enclosure. If
mounting in a metal enclosure is necessary, antenna must
protrude out of a knockout or other hole. The antenna
may not be removed or mounted remotely.
5. Connect wiring as shown in the Wiring Diagram. Use wire
sizes as specified in the Wiring Diagram.
6. The SZ-IO should be mounted no less than 3 ft (1 m) from
motorized window treatments for proper RF performance.
7. The SZ-IO must remain accessible after commissioning.
8. The SZ-IO must be connected to Earth/Ground or
Chassis Ground for ESD protection (see wiring diagram).
