The <br />pressure switch shall be actuated when the alarm line pressure reaches <br />4 -8 PSI (0,27. 0,55 BAR). <br />Pressure type waterflow switches shall have a maximum service <br />pressure rating of 300 PSI (20.68 BAR) and shall be factory adjusted <br />to operate on a pressure increase of 4 - 8 PSI (0,27. 0,55 BAR) <br />PS10 SERIES <br />PRESSURE SWITCH <br />Itrnu>sinp Knockouts <br />Inc 9 <br />W <br />-Do not tighten by grasping the switch enclosure. Use wrenching <br />nats on the bushing only. Failure to install properly could damage <br />the switch and cause improper operation resulting in damage to <br />equipment and property. <br />-To seal threads, apply Teflon tape to male threads only. Using <br />joint compounds or cement can obstruct the pressure port inlet <br />and result in improper device operation and damage to equipment. <br />-Do not over tighten the device, standard piping practices apply. <br />Pressure switch shall have one or two form C contacts, switch contact <br />rating 10.1 Amps at 125/250 VAC, 2.0 Amps at 30 VDC. <br />Pressure type waterflow switches shall have two conduit entrances <br />one for each individual switch compartment to facilitate the use of <br />dissimilar voltages for each individual switch. <br />The cover of the pressure type waterflow switch shall be Zinc die-cast <br />with rain lip and shall attach with one tamper resistant screw. The <br />Pressure type waterflow switch shall be suitable for indoor or outdoor <br />service with a NEMA 4lIP66 rating. <br />The pressure type waterflow switch shall be UL Ulc and CSFM listed, <br />FM and LPC approved and NYMEA accepted. <br />PRINTED IN USA '*G [`+C✓rlF.
