Step 6: QS Link Wiring
QS link communication uses IEC PELV / NEC
local and national electrical codes when installing IEC PELV / NEC
2 wiring with line voltage wiring.
• The total distance of the QS link wiring must not exceed 2000 ft (610 m).

* Alternate Data-Only Cable: Use approved data link cable (22 AWG [0.5 mm
twisted/shielded) from Belden, model #9461.
• Check for compatibility in your area.
• A QS system can have up to 100 zones and 100 devices. The ESN unit
counts as 1 device and up to 4 zones.
• See diagram on the right for QS link wiring.
1. Connect terminals 1, 3 and 4 to all ESN units.
2. Each ESN unit has its own built-in power supply.
3. The terminal 2 connection (24 V-) supplies power to QS devices
sharing that connection.
• Ensure that QS devices powered from terminal 2 of the ESN unit do not
consume a combined total of more than 14 PDUs.
• Refer to the documentation for each QS device to determine that device's
PDU consumption.
Note: To connect extra QS devices, use a separate power supply
(24 V-), and only connect COM, MUX, and MUX to the devices
connected to the ESN unit.
4. Wiring may be daisy chained or t-tapped.
Note: Power draw calculations are not needed for wireless sensors or
sensors connected directly to the ESN units.

WARNING! Danger of Shock. May result in serious injury or
Class
death. DO NOT WIRE WHEN LIVE! Switch off power to all power
feeds via circuit breaker before wiring or servicing the ESN unit.
Buttons and LEDs in the unit are used for programming and
troubleshooting. If line voltage shield is removed, the unit
must be accessed by a certified electrician, following local
codes.
