The IVO is activated by the IRM to dump the Releasing agent from an impulse valve container during a Fire emergency. The IRM is equipped with three capacitors that receive a constant charging current from the releasing circuit of the control panel.

Page 4: Before Installation
Before Installation The Twinflex IRM must be installed in compliance with the SRP installation manual. The installation must also meet the requirements of any local authority and BS7273 Pt1 : 2006. Positioning The module should be mounted securely and care should be taken to ensure the device is accessible for future maintenance. - Page 5 Figure 1 – IRM Layout Stuffing glands should be used on all cables to prevent stress being applied to the PCB mounted terminals. Care should be taken when terminating devices to ensure all cables are correctly sleeved and connections are secure. Improper connections will prevent the system from responding correctly in the event of a fire.

Acceptance Testing Acceptance testing shall be performed in accordance with the requirements of BS7273 Pt1 : 2006, requirements of the Local Authority Having Jurisdiction (AHJ), and the following requirements: Note: before carrying out the following tests the impulse operator must not be connected to the suppression container. -
Page 12: Arming / Disarming The System
Arming / Disarming The System To Arm the system: 1. After the system has been fully tested and restored to Normal operation, reset the IVO following the instructions provided on the Impulse Valve Operator component sheet, P/N 06-492. 2. Connect the Impulse Valve Operator (Figure 7) to the suppression container as detailed on the Impulse Valve Operator component sheet, P/N 06-492. -
Page 13: To Disarm The System
To Disarm the system: Disconnect the Impulse Valve Operator from the suppression container as detailed on the Impulse Valve Operator component sheet, P/N 06-492. Inspections & Testing The suppression system(s) shall be inspected and tested in accordance with the requirements of BS7273 Pt1 : 2006 and the Local Authority Having Jurisdiction (AHJ). -

Page 15: Operation
Operation Fault Monitoring – The IRM monitors all field wiring circuits for open and short faults. A fault is indicated via on-board LEDs at the IRM. Fault type can be determined by observing the blink pattern of active LEDs as listed in the LED table. Fault status is communicated to the SRP for indication at the panel. Disablement –... -
