STEP 1: Connect Siren to Alarm System via Wi-Fi

• Move switch from off to on position. Then go into the OSI Smart Wireless Alarm System display menu and select "Parts".
• Then on the Alarm Siren and press the "SET" button until you hear 3 Beeps then let go immediately and the light on the siren should be flashing quickly. (if you heard 4 beeps you waited too long. In this case start this step over again)
• Then go back again to the alarm display and select "Siren Learn" button. Once you see "Learn Signal Sent" on the display, programming is complete.
• Note: if you need to RESET the siren (unpair), hold the Siren Learn Button until you hear 4 Beeps.

STEP 2: Screw base onto wall

Screw base on to the wall. Ensure you use the plastic wall anchors if placing on drywall and there is no stud behind it. You do not need anchors if you are screwing into a hard surface. Once it is securely fastened to the wall place the siren over the base until notches align (you should feel the siren go in a bit. Then turn clockwise until it locks in place. If you need to remove for any reason, just twist counter clockwise and pull out.

STEP 3: Place on Window or Door

Plug in the included micro usb charging port into the siren and plug into the wall. If there is a power failure the back-up battery will last between 8 to 10 hours. Once power resumes it will automatically recharge the internal lithium back-up battery.
