5.4 Wiring Relay General guidelines
Adhere to the following guidelines when wiring base panel relay modules. These guidelines and specifications apply only to the standard,
on-board relays. Information regarding the specifications and wiring of the optional auxiliary relays is located in Simplex document
579-359, Simplex Auxiliary Relay Module, Installation Instructions.
• All wiring must be 18 AWG minimum to 12 AWG maximum.
• Conductors must test free of all grounds.
• Relay circuits are rated for 2A (max.) at 30 VDC (max.), pilot duty (0.35 power factor).
• Circuit is not supervised.
• When setting jumpers to select Normally Open or Normally Closed contacts, position jumpers as follows:
Normally Closed, position jumper to the left.
Normally Open, position jumper to the right
• All relays are single pole, double throw.
• If power source is not power limited to the requirements of UL864, wiring is to be segregated to the non-power limited spaces of the
cabinet. See Field wiring AC power and battery wiring for the location of the non-power limited cabinet area.
• When SPM wiring is routed outside the building, use Listed Secondary Protector 2081-9044 or 2081-9028. A protector must be
installed at the building entrance such that protected wiring is segregated from unprotected outdoor wiring.

5.5 Wiring notification appliance circuits guidelines
Adhere to the following guidelines when wiring Notification Appliance Circuits (NACs).
• All wiring is to be 18 AWG minimum to 12 AWG maximum.
• Conductors must test free of all grounds.
• All wiring is supervised and power limited.
• Leave a 10K, 1/2 W (378-030) resistor across all unused NAC terminals. See item 4 in Figure 24.
• Terminate Style Y (Class B) circuits with a listed 10K, 1/2 W (Simplex Part Number 733-894) end-of-line resistor. See item 5 in Figure 24.
• For Canadian applications, use ULC-listed end-of-line resistors 2081-9038C, 2081-9123C, or 2081-0002.
• Terminate Style Z (Class A) circuits with a listed 10K, 1/2 W (Simplex Part Number 733-894) end-of-line resistor. See item 6 in Figure 24.
• Voltage rating – nominal 24 VDC, 0.5 V peak-to-peak ripple maximum.
• The total available current from main power supply is 3 A. If auxiliary power is used, available signal power is reduced accordingly.
• Terminal designations "+" and "-" are for the alarm state.
• Compatible appliances: 4901 series horn, 4903, 4904, and some 4906 series A/V and V/O. Maximum 70 appliances on a circuit, see
Appendix C Compatible notification appliances, accessories and releasing devices.
