The One Time in Their Life... It's dark - there's a sound - then the siren blasts. Your customer is going to immediately enter their code. Every other system in the world will disarm, silence and send a cancel signal to your central station. The one time in their life that your customer really needs an alarm system, it gets turned off . Not with DMP. You can sell a system that allows the customer to leave it on and decide if this is a real emergency. Don't install anything less.
