ARG-WL8Ex-CP
Wireless intrinsically safe manual call point

The wireless intrinsically safe manual call point is a fully intelligent device which is compatible with all Streletz Translator and Expander Modules. The unit has a resettable plastic element, which displays a drop down warning flag when operated. A key is supplied with the MCP for reset and case opening.

FEATURES: 
Bi-directional wireless communication
IEC classification: 0Ex ia IIС T6 Ga X / Eх ta ia IIIC T(200)50°C Da X
Self-optimizing wireless frequency and amplitude algorithms

ARG-WL8Ex-EXP
Wireless intrinsically safe expander module

The wireless intrinsically safe expander module compatible with ARG-WL8-TRV wireless translator module. The unit provides a convenient method to increase radiocommunication range beyond that possible from a single translator by relaying the radio communication to further expanders or directly to the wireless field devices. This functionality makes it possible to build large fully wireless systems or add wireless devices into areas where cabling for translators is difficult or impossible. All expanders are fully monitored ensuring the highest levels of life safety and reliability are maintained. Using well-proven wireless technology and an orthogonal antenna design ensures the highest levels of life safety and system reliability.

FEATURES: 
Dynamic routing for all expanders and field devices
Bi-directional wireless communication
IEC classification: 0 Ex ia IIC T6 Ga X / Ex ta ia IIIC T(200)80°C Da X
Compatible with up to 256 field devices
Supports full device intelligence
Ingress protection rating – IP65
5 years product warranty

ARG-WL8Ex-FL
Wireless intrinsically safe flame detector

The wireless intrinsically safe flame detector monitors the protected area and provides early detection of an open fire. An alarm message is sent to the control panel through its wire to wireless translator module and, eventually, one or more wireless expander modules.

FEATURES: 
Bi-directional wireless communication
IEC classification: 0Ex ia IIС T6 Ga X / Eх ta ia IIIC Т(200)80°С Da X 
Operation range 25 meters
Dual sensor
Self-optimizing wireless frequency and amplitude algorithms
5 years product warranty
