Model Il-C provides automatic-pneumatic actuation of fixed nozzle fire suppression systems. DescrIPtIon The Model Il-C is comprised of a metal enclosure which contains a spring-loaded puncture pin release mechanism, an actuation cartridge, and an explosion-proof electrical solenoid. Knockouts for the connection of conduit are provided in the top, bottom and sides of the steel enclosure. The enclosure also contains four surface mounting holes. operation When energized by a fire condition, a solenoid mounted on the actuator trips the release mechanism puncturing the cartridge. The solenoid operates approximately 50 milli - seconds after energized. Then actuation gas from the cartridge is directed through piping to pneumatically activate the fire suppression system. Manual actuation is provided by means of an integral STRIKE button at the release enclosure which may be supplemented by use of a remote manual cable pull station.

InstallatIon InstructIons E 62842 6-1-11 Page 2 MountInG ansul automan Il-c release The reliability of an ANSUL fixed nozzle fire suppression system depends greatly upon proper installation of the releasing device, associated equipment and wiring. For example, the ANSUL AUTOMAN Il-C utilizes a special pressure cartridge activating a fire suppression system that must be located in an area where the air temperature will not fall below 32 F (0 C) nor exceed 120 F (49 C). This requirement and other instructions to follow are critical to reliable operation. Install release 1. Select a shock and vibration free surface in a clean dry area for mounting the ANSUL AUTOMAN release. The mounted release should be completely visible and accessible for maintenance. note: The bottom of the release must be located no higher than 50 in. (127 cm) from the floor to enable manual actuation of STRIKE button. If the release cannot be mounted in this manner, a remote manual pull station (cable type or electric) should be installed to facilitate manual actuation. 2. Open the release cover and secure the enclosure at location utilizing the four mounting holes. Use lag screws or toggle bolts depending on the mounting surface. Figure 2 provides detailed mounting data. MountInG Data 3. DO NOT INSTALL CARTRIDGE AT THIS TIME. 4.
