4010ES IDNAC Fire Alarm System Installation Guide
Note: Output of AUX or NAC is 24V nominal. Minimum voltage is 19.5 @ full load and minimum battery; maximum is 31.5V at light load,
high AC line. Aux Loads include 4602-9101 Annunciator, 4100-94xx series Annunciators, 4090 series of IDNet ZAMs and IAMs and any
Listed device operating within the output limits of the AUX. Calculate wiring loss for actual devices used. Compatible appliances include
4904 series of free-run strobes, 4901 series non-smartsync horns, 4098 series TrueAlarm Sounder Base, 4090-9005 & 4090-9006 SRP and
4009 NAC extenders, used in reverse-polarity activation mode.
7.4     ESS Auxiliary relay wiring Guidelines
The ESS includes one on-board, programmable relay.
• All wiring must be between 18 AWG (0.8231 mm
2
) and 12 AWG (3.309 mm
2
).
• When power through auxiliary contacts is provided by the ESS, wiring is power-limited.
• When power through auxiliary contacts is not provided by the ESS, use an in-line fuse (208-165). If the 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.
• The relay circuit is not supervised.
• The relay circuit is rated to switch 2 A at 30VAC or 30VDC, resistive load.
• Relay contacts are Form C dry contacts. Suppression is provided to earth. Do not switch voltages greater than rating, or damage may
result.
