The PS-4-DB2-7240 Power Supply Units (PSUs) provide the monitoring and standby capabilities required by AS7240.4 - offering 2A or 4A alarm output.

The units feature an input that can disable battery charging during a fire condition, allowing the full output capacity to be directed to connected equipment. This maximises available output current while maintaining monitoring and protection of the outputs. This flexibility allows the appropriate standby duration (eg 24 or 72hours) to be selected to suit system requirements.

Each unit is housed in a surface-mounted steel enclosure, complete with knockouts for top, bottom or rear cable entry.
