NONEL® EZTL™ 1.1
|
NONEL nonelectric delay detonator EZTL units consist of a length of yellow shock tube, with a surface detonator attached to one end and the other end sealed. The detonator is housed in a plastic EZ Connector block which facilitates easy connection to shock tube. A white J-hook is affixed near the sealed end. Easyto-read, color-coded delay tags display the delay number and nominal firing time prominently.

EZTL detonators are designed for use with NONEL MS and EZ DET® units to provide effective and accurate surface timing between blast holes and/or rows of blast holes in surface and underground blasting designs.
APPLICATION RECOMMENDATIONS
• For detailed application recommendations, ALWAYS request a copy of Dyno Nobel’s Product Manual: NONEL® and PRIMACORD® from your Dyno Nobel representative.
• ALWAYS be sure that the shock tube(s) are securely inserted, one at a time, into the plastic EZ connector. The head of the connector block should rise to accept the tube, and return to a closed position with an audible click
• ALWAYS ensure that the individual shock tubes remain aligned side by side in the EZ connector channel and do not cross over one another during insertion.
• ALWAYS protect the plastic EZ connector and all shock tube leads from impact or damage. Use care when placing blasting mats and cover material on top of the blasting circuit. The EZ connector contains a detonator and is subject to detonation caused by abuse such as impact. Shock tube which has been cut, ruptured or damaged may cause misfires
• NEVER use NONEL EZTL detonators with detonating cord. The low strength surface detonator will not initiate detonating cord
• NEVER attempt to disassemble the delay detonator from the EZ connector block or use the detonator without the connector
• NEVER place more than 6 shock tube leads into an EZ connector block, misfires may result
• NEVER tie-in NONEL EZTL units to the blast initiation system until all blasthole surface connections have been made and inspected. Ensure the blast site has been cleared. It is important to remove nonessential personnel and equipment prior to the hole-tohole connection process.
