Page 3: General Description
General Description The SRM (Solenoid Releasing Module) is a module that controls the operation of the Solenoid valve(s) in a Suppression system. The typical applications where the SRM can be implemented for are – Pre-action sprinkler, Deluge, CO2, Water mist and Foam. The SRM can be used to monitor a Discharge Pressure switch to provide feedback to the Control Panel that the Releasing agent has been dumped into the protected space. -
Page 4: Before Installation
Before Installation The Twinflex SRM 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 – The SRM 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 a system from responding correctly in the event of a fire.

Page 6: Connections
Connections In order to carry out high voltage testing and resistance measurements, temporarily connect the incoming and outgoing zone cables to each other using a 3-way connector block. Once all testing has been carried out on the cabling, and ‘continuity & integrity’ has been proven, the SRM may be connected and assembled. -
Page 7: Zone Connections (J1)
Zone Connections (J1) Figure 3 shows how to make the zone positive, zone negative and screen connections between the SRP panel and the SRM(s). Figure 3 – Zone Connections Please note that the “SCREEN” terminals on the SRM should only be connected to the zone cable screen and NOT to the building earth or the back box earth terminal. -
Page 8: Solenoid Connections (J2)
Solenoid connections are power limited and supervised. The Solenoid connection (12 or 24 volt) requires an EOL circuit supervision assembly (Part# 17-0144), provided by Fike, to be installed between the SRM and the solenoid coil. The assembly provides a means to monitor the solenoid wiring for open and short faults. -
Page 9: External Power For Solenoid (J3)
External Power for Solenoid (J3) A 24V DC 2A External Battery Backed Up power supply is required to power the solenoid to dump the Releasing agent. The 24V DC power can be supplied by the SRP panel AUX PWR 1 & AUX PWR 2 terminals. -
Page 10: Input Connections (J4, J5, J6)
Input Connections (J4, J5, J6) Input connections on Terminals J4, J5 and J6 are all contact closure inputs. The inputs can be individually configured (via DIL switch SW2) to be normally open or normally closed. Figures 6 and 7 show how to make input connections. -

Page 12: Acceptance Testing
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 Solenoid must not be connected to the suppression container. -
Page 13: Hardware Connections
Hardware Connections After the acceptance tests connect the solenoid valve (Figure 8) according to the valve manufacturer’s instructions. A Supervision Assembly must be used between the solenoid and the SRM, see Figures 4 & 5. The maximum cable length between the solenoid and the SRM must not exceed 3 metres. -
Page 14: Dil Switch Sw2 Settings
DIL Switch SW2 Settings The SRM can be configured via an on board DIL switch SW2 as per the table below. The last device on the zone circuit must have the EOL signal enabled (switch number 1 in the ‘ON’ position). Switch Configuration position... -

Page 16: Operation
Operation Fault Monitoring – The SRM monitors all field wiring circuits for open and short faults. A fault is indicated via on-board LEDs at the SRM. 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 panel for indication at the panel. -
