ALR 4+3PF Card Description (8402)
The ALR 4+3PF Card has four outbound switches and three inbound sensors. This card is
similar to the ALR 4+4 Card, except that its fourth alarm port can only be used as an outbound
alarm to show the system power unit has failed. The ALR 4+3PF Card is especially helpful in
locations where a loss of power to any system units is a critical problem. See Figure 1-2.
A -48 VDC power source is optional with this card. It may be provided by either an
AC-to-DC Converter or an external source.
