Secware Posted February 8, 2013 Share Posted February 8, 2013 These PIRs require a power supply of min. 9V which I intend to draw from the Powermaster Central 12V auxiliary output, as it is backed up by a battery. The PIRs consume 19mA max, so 38 mA in total, which exceeds the Powermaster specs of 36 mA max for this auxiliary output. Can you suggest an alternative power output please, or do you think it's no problem to connect the PIRs as planned to the Central. Quote Link to comment Share on other sites More sharing options...
Secware Posted February 8, 2013 Author Share Posted February 8, 2013 I would recommend using the expander board 9-100775 and fitting that to your PowerMaster 30. Once fitted that should give you 450mA to work with. http://www.securitywarehouse.co.uk/catalog/index.php?main_page=product_info&products_id=2199 Quote Link to comment Share on other sites More sharing options...
Secware_Tech6 Posted February 16, 2013 Share Posted February 16, 2013 Or power the devices from a 12v PSU ie http://www.securitywarehouse.co.uk/catalog/index.php?main_page=product_info&products_id=3485 Quote Link to comment Share on other sites More sharing options...
