Installation

Input Channels

When the panel is ready to have power applied, connect the battery cable plug to connector J3 on
the 411UDAC main circuit board. The battery charger is capable of recharging sealed lead acid
type batteries. Refer to the battery calculations table to determine the correct battery rating.

2.4 Input Channels

The 411UDAC has four channel inputs. Channel/input field wiring is supervised for opens (trou-
ble), shorts (alarm) and ground faults (zero ohms impedance between panel and earth ground) by
the 411UDAC. All conditions are visually and audibly annunciated and, if programmed, communi-
cated to a Central Station.

Each channel is a Style B (Class B) Initiating Device Circuit with the exception of channel/input 3
which can be configured for Style B or Style D (Class A). All inputs can be connected to normally-
open contact type devices. In addition, inputs 1 and 3 can be connected to conventional 4-wire
smoke detectors. Figure 2.5, “Wiring Initiating Device Circuits” on page 23 for information on
wiring Style B and Style D circuits.
