Has any one run across a stand alone door prop alarm similar to the detex pg 21 that has an alarm delay longer than 45 seconds? I have made such an alarm with an altronix timer but it would be simpler to use a stand alone unit such as the detex. Thanks in advance.
A timer is probably the cheapest way out. You probably ought to check with IEI, they may make a similar device without getting involved with a keypad.
Can't be too hard to mod an EA-500 to do longer than 45 seconds... Have you asked Detex?
