Spectron-512-Exd-A/N-IPR Explosion-proof Manual Fire Alarm Call Point

Designed for manual activation of the Alarm signal in fire alarm and fire extinguishing systems 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-IPR-A/B, Spectron-512-Exd-A-IPR-A/B-HART/Modbus is made of aluminum alloy;
• Housing of Spectron-512-Exd-N-IPR, Spectron-512-Exd-N-IPR-A/B-HART/Modbus is made of stainless steel.

• Spectron-512-Exd-A-IPR-A, Spectron-512-Exd-N-IPR-A, Spectron-512-Exd-A-IPR-A-HART/Modbus, Spectron-512-Exd-N-IPR -A-HART/Modbus detectors are manufactured by class А;
• Spectron-512-Exd-A-IPR-V, Spectron-512-Exd-N-IPR-V, Spectron-512-Exd-A-IPR-B-HART/Modbus, Spectron-512-Exd-N-IPR -B-HART/Modbus detectors manufactured by class B.

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.

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