GE 2 Amp Supervised Power Supply For The Concord 4
Installation Instructions
Description
The power supply provides an additional 12 VDC, 2 amps (current limited) for Concord 4 system devices and is supervised via the SuperBus® 2000 digital data bus.
Note: For 24 hour backup, external power drain is limited to 95mA (during normal standby conditions) using a 4.5 Ah battery, or 190mA continuous using a 7.0 Ah battery.
The power supply uses a 24 VAC, 50 VA power transformer. In case of an AC power failure, a 12 VDC, 4.5 or 7 Ah backup battery (not included) provides power to connected devices. The battery is tested by the power supply on power up, every two minutes afterward, and whenever the panel tests its own backup battery.
The power supply also includes a hardwire zone input that accepts normally open (NO) or normally closed (NC) intrusion detection devices. The power supply can be located inside the Concord 4/Concord Express V4 cabinet or it can be mounted in a separate Concord Residential Enclosure (444-1700 and 444-1711 ordered as a separate kit) or Concord Commercial Expansion Enclosure (444-1391 ordered as 60-816). See Mounting inside panel cabinet on page 2, Mounting inside Concord residential enclosure on page 2, and Mounting inside Concord Commercial enclosure on page 3 for more information on mounting in a separate enclosure.
Figure 1 describes the power supply main components. by the wire runs needed to provide power to devices with minimal loss on the +12V OUT wire. Table 1 shows the maximum wire runs between the power supply +12V OUT terminal and the devices it will power.
For UL installations, the +12V OUT is not fully supervised for open circuits. Therefore, sirens cannot be connected directly to the output. • For large installations with long wire runs, power supply location is important. The total system wiring length (all partitions) for all bus devices connected to a Concord 4/ Concord Express V4 panel must not exceed 4,000 feet. This not only includes the power supply bus and power connections to the panel, but also any bus devices you may connect to the power supply. For example, touchpads and other bus devices in a remote partition should be connected to the power supply rather than running the wires all the way to the panel (Figure 2). Table 1.
