Hello all,
I have a Motorola CDM1250 that I am trying to set up to an alarm box at a local fire station. The alarm is activated when voltage is applied to a certain pin on the alarm board. The problem I am having is Pin 4 on the CDM1250 (which is set for External Alarm output) has constant voltage and when the radio receives a selective call, the voltage drops a few mili-volts. Is there a way to make the radio pulse a voltage for a certain period of time when a selective call is received to activate the alarm box and then drop the voltage after the call has been received? Is there any way this can be done on the CDM1250? In an old setup, we had the Minitor amplified base which was able to perform this action but it doesn't appear the CDM1250 can do the same thing? Any thoughts?
Thanks,
Nick
