NEX7250 - A fully Featured Hazardous Area Alarm Annunciator

A hazardous area Annunciator offering all the features and benefits of a safe area Annunciator from RTK Instruments

RTK Instruments’ NEX7250 Alarm Annunciator is a feature rich annunciator suitable for use in Zone 2 hazardous areas and designed to Type ‘n’ standards.

Designed to ATEX Directive 100a in accordance with EN50021:1999, the NEX7250 is based on the field-proven Series 725 Annunciator. Systems are available in a range of sizes and formats from 2 to 120 windows, in a choice of three different window sizes and six colours. Windows are illuminated by ultra-bright, ultra reliable LEDs.

As with all RTK’s range of Annunciators, ASIC technology is used in the NEX7250 to maximise reliability. This multi-redundant design ensures no single point can cause failure.

The standard unit comprises a wall mounting steel enclosure with hinged plexiglass viewing window sealed to IP54. Options include panel mounting versions or stainless steel enclosures.

The NEX7250 is fully field-programmable for all standard ISA sequences plus a range of options. Units are equipped with dual common alarm and dual horn relays as standard. Options for RS485 serial interface and individual repeat relays per channel are also available.

RTK Instruments, as major suppliers of industrial alarm systems and components for safe and hazardous area, can also supply complete alarm systems and help with all industrial alarm applications.
