DSC PK5508 keypad trouble

The builders of my house hardwired the security system but I dont want to pay for monitoring service. I hooked up power and battery to the control box, now my keypad is beeping every 10 seconds and has the yellow triangle trouble light. Anytime I press a button it gives a long beep, stops, then continues beeping every 10 seconds. My online searching just brings up how to look up the error codes to see what the problem is, but I can’t get to that without the long beeps and nothing happening. Help!
