Manual fire alarm IPR535 HORIZON

The IPR535 Gorizont MK fire alarm is designed for manual activation of fire alarms in hazardous areas. The IPR 535 Gorizont "Pusk" MK manual actuation device is designed to activate actuators of fire extinguishing systems, smoke exhaust systems, and other systems. It has an explosion protection rating of 1Ex d IIB T6 Gb. Full compliance with the 2012 edition of GOST 53325.

The detector can be used as a stand-alone element or in alarm loops (AL) with either a shorted (parallel connection) or open (series connection) connection. Two-color status indicator: standby mode indication – green flashes with a period of 5-7 seconds; alarm mode indication – red flickering with a frequency exceeding 5 Hz.

Class according to GOST 53325-2012: manual alarm – class A (activation by one action); manual start devices – class B (activation by two actions).

The IPR 535 Gorizont detector is designed for manual activation of a fire alarm in a hazardous area. The detector is intended for installation in hazardous areas of class 0 and below.

The IPR535 Gorizont MK detector is supplied with cable entries of various designs:

for open installation of the connected cable (index in the designation - K );
for laying the connecting cable in a G1/2 ( T-1/2 ) pipe;
for laying the connecting cable in a G3/4 ( T-3/4 ) pipe;
for connecting armoured cable ( B );
for connecting a cable in a metal sleeve RZTSKH-15mm or 20mm ( KM15, KM20 ).

The IPR535 Horizon detector is supplied with two cable entries, which allow the detector to be installed in an alarm circuit with a round cable with a diameter of 6-10 mm.
