Alarm Fan Guard
Alarm Fan Guard for SubFloor Ventilation
Install the hose connector at the bottom edge of the fan’s side or end panel; drill a 6 mm hole and secure the connector with a dab of silicone or flexible sealant (This applies to fan kits 50 and 100; fan kit 150 has a pre-installed connector at the bottom of the fan housing. On fan package 70, attach the connection nipple somewhere on the exhaust duct).
Install the pressure switch on the fan and connect the hose from the pressure switch's negative (-) outlet to the fan's connection nipple. Also, remove the protective cap from the positive (+) outlet.
Install the alarm light/operating light in the desired location and have a qualified electrician connect it to a 230V power source via the pressure switch, which functions as a power switch. Note that the alarm function must not be connected to the same fuse as the fan; otherwise, the alarm will not sound if the fuse blows.
The alarm kit can also be connected to an existing alarm system for installations (such as DUC).
