Installation
3.5 Connecting the Power Cables
3.5.1 Overview
Complete all mounting procedures and check all wiring before applying power. Electrical
connections include the following:
•
Primary AC power source – 120 VAC, 50/60 Hz, 5.0 A from line voltage source (with IQ-
318E use 220-240 VAC, 50/60 Hz, 2.5 A). Overcurrent protection for this circuit must comply
with Article 760 of the National Electrical Code (NEC) and/or local codes. Use 12 AWG (3.31
mm
2
) wire (maximum) with a 600-volt rating.
•
Secondary power source – 24 VDC from batteries, installed in the control panel (or in an
optional battery cabinet). Secondary (battery) power is required to support the system during
loss of primary power.
•
External power sources – 24 VDC power for Smoke Detectors (4 wire), NACs, and
Annunciators.
•
Auxiliary power source – 24 VDC power @ 0.5 A and 5 VDC power @ 0.15 A from TB2 on
the CPS-24/E.
See Appendix 7 “Electrical Specifications” for details and overall installation guidelines.
3.5.2 Connecting the Control Panel to AC Power
Connect primary power as follows (see
Figure 3.4):
1. Turn off the circuit breaker at the main
power distribution panel.
2. Open the hinged insulating cover on TB1.
3. Connect the service ground to terminal
marked Ground (Earth).
4. Connect the primary neutral line to terminal
marked NEUTRAL and the primary Hot line
to terminal marked HOT.
5. Close the hinged insulating cover over TB1.
3.5.3 Checking AC Power
Table 3.2 contains a checklist for checking the system with AC power applied:
!
WARNING:
Remove all power sources to equipment while connecting electrical components. Leave the
external, main power breaker OFF until installation of the entire system is complete.
!
WARNING:
Several sources of power can be connected to the control panel. Before servicing the control panel,
disconnect all sources of input power
including the battery
. While energized, the control panel and
associated equipment can be damaged by removing and/or inserting cards, modules, or
interconnecting cables.
