SMOKE DETECTION SENSOR
Installation Instruction
The E-SDS(-CE) is a smoke detection sensor intended for connection to an NTI
for use in detecting smoke in a server cabinet environment.
SYSTEM that with proper configuration will result in alert messages being sent to the administrator of the SYSTEM. The E-SDS(-CE)
has screw terminals for easy user connections.
Options:
 E-SDS-PA also includes a 12VDC (regulated) AC adapter with country-specific line cord (add "-PA" to the model
number).
 E-SDS-CE(PA): CE certified (add "CE" to the
model number
 E-SDS-CE-E7: CE certified model with pre-wired
7 foot cable and coupler (can be extended 1000 ft with 24AWG
CATx cable) for plug-in to RJ45 Sensor port or wired pigtail to a
Digital Input.
Disconnect the Base
Remove the base from the detector head. To remove the base, locate the long and short alignment marks on the side of the base.
When the detector head is locked to the base, the alignment mark on the detector head lines up with the long alignment mark on the
base (see image below). To release the base, rotate the base to align the shorter alignment mark on the base with the mark on the
detector head. Once they are aligned, pull the detector head apart from the base.
Install the Base
Mount the base of the E-SDS(-CE) where smoke detection is desired.

Summary of Contents for NTI E-SDS

  • Page 1 When properly connected, this sensor will provide signals to the SYSTEM that with proper configuration will result in alert messages being sent to the administrator of the SYSTEM. The E-SDS(-CE) has screw terminals for easy user connections.
  • Page 2 Power Connection For Model E-SDS(-CE): Connect two 18-22awg wires (not supplied) between the E-16D and the E-SDS(-CE) as shown below. (Wiring for E-2D and E-5D also shown.) a. Connect one wire between “12V” on the SYSTEM and terminal 2 on the smoke detector.
  • Page 3 When a 12VDC power supply is not available on the SYSTEM (for example, E-MINI and E-MINI-LXO do not include terminals to provide 12VDC power to sensors), model E-SDS-(CE)PA can be used. Connect the AC adapter wire labeled “PLUS 12” to terminal 2 on the smoke detection sensor.
  • Page 4 For Model E-SDS-CE-E7: The E-SDS-CE-E7 includes a 7 foot pre-wired cable with RJ45 connector (wiring shown below) for plug in to either an available RJ45 Sensor port in an E-2D/5D/16D or into a pigtail wired to a Digital Input on an E-2D/5D/16D.
  • Page 5 Sensor port, a smoke detector in alarm must be manually disconnected and reconnected in order to reset it. The E-SDS(-CE) draws 30mA @ 12VDC To wire your own CATx patch cable to an E-SDS(-CE) sensor, follow the wiring instruction below.
  • Page 6: Operation

    LONG ALIGNMENT MARK SHORT ALIGNMENT MARK Operation 1. Connect the AC adapter to a 100-240VAC power source. The LEDs on the E-SDS(-CE) will blink red to indicate the sensor is functioning and in status-ready condition. The LEDs will illuminate solid red when smoke is detected.
  • Page 7 Application Note: A smoke detector connected to an RJ45 Sensor Port does not have “Cycle Sensor Power” button and must be manually disconnected (unplugged) and reconnected in order to reset it. To use this feature, make sure the smoke detector is wired to a Digital Input. Cycle Sensor Power on E-MINI-LXO The power to the smoke detector can also be power-cycled on the E-MINI-LXO when wired as shown on the lower image on page 3.
