The low-voltage detector (if working properly) will stop the siren and prevent further activation when the voltage drops below 40 VDCJim Z wrote:see, I'm wondering what the low-voltage cutoff is for the Federal DC sirens. that thing only ran for 20 seconds. If, say, the batteries weren't recharged after the last use, then that could be an explanation.
Also, with the 2-way controller, the EMA or city will receive notification of the problem. It also warns of charger problems, intrusion, and there may be several other message alerts
Here are the specs on the DCFCTB (2001 2-way controller):
