December 6, 201015 yr Hi, i bought a powermax plus alarm, and have just attached the external sounder to complete the system (risco novagard6), however, upon arming and disarming using the keyfob, the external sounder sounds for 1 second. this doesnt happen if i use the keypad on the pm+ though. Please could you point me in the right direction.
