TII 325 NIZ MAXIMUM DUTY ONE PAIR STATION PROTECTOR WITH NETWORK INTERFACE
TII 326 NIZ HEAVY DUTY ONE PAIR STATION PROTECTOR WITH NETWORK INTERFACE
TII 126 NIZ HEAVY DUTY ONE PAIR STATION PROTECTOR WITH NETWORK INTERFACE
UL LISTED
The TII 325 NIZ, 326 NIZ and TII 126 NIZ Station Protectors with Network Interface consist of a mounting base optional encapsulated station protector module, and a network interface cover assembly.
The unit is molded from a resilient rugged plastic material. The cover assembly consists of an RJ11 plug and jack with weather resistant grommets, a customer wiring bridge, a provision for mounting an optional electronic circuit such as a TII 856 half-ringer or a 807 MTU circuit,
and a hinged top cover with customer wiring instructions. The lockable cover has a Telco override for service entrance and is available with a hex head or pin-in-head cover screw. The cover assembly attaches to the mounting base with a captive, nylon cover nut. The subscriber is
totally isolated from the telco wiring and station protector and is protected from accidental contact with the customer bridge terminals.

The TII 355 TFS Maximum Duty 3-Electrode protector module is used in the 325 NIZ. The TII 326 NIZ line utilizes the TII 356 TFS Heavy Duty protector module. The 355 and 356 protector modules consist of a 3-electrode gas tube with a failshort
mechanism which operates to permanently ground both sides of the line under a power cross condition and an integral device which provides air gap protection in the rare instance when the gas tube vents. The sealed module excludes moisture, providing protection against premature
shorting, corrosion and noisy circuits. This superiority makes these station protectors particularly suitable for use where heavy surges rae likely to occur, especially where aerial wire, rural distribution wire, or long drop runs are used.
The TII 126 NIZ utilizes the TII 126 TFS Heavy Duty 2-electrode protector module. The 126 protector module has two Heavy Duty gas tubes which provide an extra level of protection in both life and current handling capacity beyond that of most 2-electrode gas tubes
in common usage today. The 126 protector module also contains a failshort mechanism in case of a power cross condition, a backup airgap, an epoxy sealed shell with two #10 wiring studs and a ground strap. The encapsulation of the internal components of the module safeguards
against contamination and corrosion of the protection elements, a feature not found in screw-in type station protectors.
