• Spectron-512-Exd-N-UDP-03 "EMERGENCY EXIT" - green housing.

Explosion protection marking allows the devices to be used in hazardous areas zones 1 and 2 of enclosed facilities and outdoor installations, as well as in underground mines, mining plants and their above-ground facilities.

• Housing of Spectron-512-Exd-A-UDP is made of aluminum alloy;
• Housing of Spectron-512-Exd-N-UDP is made of stainless steel.

Spectron-512-Exd-A-UDP-01 (set 8.3) – special version of UDP supplied with SZK-14 sun visor, cable glands for cable in a metal hose with nominal diameter of 20 mm (4 pcs), stopper plugs (3 pcs), resistors for connecting to an addressable expander (S2000-AP2), explosion-proof junction box Relion-KKV-A.

Call point in stainless steel housing is recommended for use in facilities exposed to acidic, alkaline and other chemically aggressive environments, sea water and salt fog.

• Call points with "Modbus" index for data exchange are equipped with a digital RS485 interface supporting the Modbus RTU protocol;
• Call points with "HART" index for data exchange are equipped with a 4÷20 mA current loop interface with support for HART technology.

Call point remains operational at temperatures from -70 to +85 ºС.

Environmental Standards in accordance with GOST 15150: UHL1, OM1

The absence of magnets in the device increases its reliability and allows the call point to be installed in areas with a high magnetic field.

The call point is reset to Normal mode using a special key.

Self-testing function increases the reliability of the fire alarm system.

ATTENTION. The model of cable glands must be specified when adding to the specification and ordering the equipment. Cable glands are not included in the price of the equipment. Full information on cable glands is available on the CABLE GLAND page of our website . If you have any questions about the correct selection of the type of cable gland, you can contact the technical support service by phone.
