AMP-4 prot.R3

Fire Address Mark AMP-4 prot. R3 is designed to be connected to address system of non-addressable fire and security alarm detectors, reader Wiegand, to control announcing system, engineering systems and to communicate information on the state of alarm loop to receiving and controlling device. It is designed to operate as a part of address system controlled by receive-control alarm device Rubezh-2OP prot. R3.

Address mark AMP-4 prot.R3 provides:

  • connection with non-address safety, heat, fume, manual or linear fire detectors;
  • safety reset of the loop to prevent from false alarm;
  • functional check of alarm loops and output control lines of indicator for break and short circuit;
  • control of annunciators - indicator panels and audible alarms;
  • different modes of power outputs operation;
  • activation/deactivation of save areas using Proximity-card reader operating in Wiegand format or by means of commands sent from Rubexh-2OP prot. R3
  • control of external devices, for example EM lock using clapper relay of dry contact type by commands sent from fire alarm control and indicating equipment or using Proximity cards.

Module power supply is realized from external power source of 12 or 24V.

Address communication lines are electrically isolated from address mark power lines.

In the system, the address mark represents eight individual logical devices with corresponding number of addresses allocated:

  • 4 alarm loops;
  • 2 outputs with circuit break control;
  • 1 output of dry contact type;
  • 1 Wiegand interface. AM-4 prot.R3 address mark may be installed in DIN rail using special securing bar (not in the scope of supply;
  • may be provided by separate order).

Types of control loops of heat and fumes fire detectors, security detectors:

Type 1 - fume alarm loop with control of short circuit and break to connect with stand alone fume detectors, manual detectors, linear detectors. When one of the alarms in the loops triggers, address mark switches to "Fire 1" state (when safety reset is activated, switching is done after repeated triggering of one alarm  after safety reset). The address mark switches to "Fire 2" state only when two fume detectors or one manual detector are activated.

Type 3 - heat alarm loop with control of short circuit and break to connect with stand alone heat detectors. When one of the heat detectors triggers, address mark switches to "Fire 1" state; switching to "Fire 2" state is initiated only when two heat detectors are activated.

Type 6 - safety loop to connect with security detectors with output of dry contact, NC or NO type. Address mark switches to "Alarm" state when any detector is activated or loop break or short circuit takes place providing that security mode of the loop is activated.

In the diagram, the following connections are depicted:

  • with AL1 of security alarms (AL1 has security type of loop - type 6);
  • with AL2 of fume and manual detectors (AL2 has fume type of loop - type 1).
