4.5.7 Wiring the Alarm Output Contact
The location of the Alarm Output Connections (TB1) is shown in Figure 4-1. A magnified view of this area on
the motherboard is shown in Figure 4-11.
• Wire gauge selection of the Alarm Status output contact wiring involves consideration of all factors
including, wire loop length, maximum current capacity, and maximum voltage drop allowable.
• The Alarm Status output contact is Form C, rated for 2.0 amps at 24VDC, resistive load.
• For terminal connection details of the Alarm Status output contact (shown in the non-alarm mode), see
Figure 4-11.
• Contacts are duplicated for ease of IN and OUT wiring.
• An external 24VDC or the internal 24VDC connection (TB1) can be used to power non-supervised
Alarm appliances.
