Could you just put a single head below the diffuser, on the side close to the return grill, and let that head serve as protection under both obstructions? Or drop a single head with a water shield right between the two?
It looks like the actual area would be small enough to be covered by one sprinkler. -Kyle M From: Luis Perea <[email protected]> Sent: Wednesday, October 5, 2022 2:19 PM To: 'Discussion list on issues relating to automatic fire sprinklers' <[email protected]> Subject: [EXTERNAL] [Sprinklerforum] ESFR Sprinkler Under Obstruction Hi everyone, Per NFPA-13 i can´t find if it's mandatory to install a sprinkler under the HVAC extraction Grill, the size of the duct it is clearly an obstruction and the option i have been thinking is to install the sprinkler with a baffle under the grill. Does anyone know if this is correct or have any other solution? [cid:[email protected]] Thank you. LRPF
