The SpectrAlert Advance series of notification appliances is designed to simplify installations, with features such as plug in designs, instant feedback messages to ensure correct installation of individual devices, and field-selectable candela settings. When installing the P2RHK-120, first attach the 120V mounting plate to the outdoor back box provided with each unit. Next, connect the notification appliance circuit wiring to the SEMS terminals on the mounting plate. Finally, attach the horn strobe to the mounting plate by inserting the product's tabs in the mounting plate's grooves. The device will rotate into position, locking the product's pins into the mounting plate's terminals. The device will temporarily hold in place with a catch until it is secured with a captured mounting screw. The SpectrAlert Advance series outdoor notification appliances are rated between minus 40 deg F and 151 deg F in wet or dry applications.
