Bosch | 7/05 | 31499J

Storage and Operating Temperature: +32° to +120°F (0° to +49°C)

Input Power: 120 V, 60 Hz, 1.5 A (maximum 2.0 fused supply circuit)

NAC Power: Each NAC has 24 VDC nominal, unfiltered (special application) power with up to

2.5 A capacity, but limited by overall 4.0 A capacity. Refer to the Technical Service Note

(P/N: 34950) for compatible NAC devices.

Auxiliary Power: 24 VDC nominal, unfiltered, 1 A (special application)

Initiating Circuit Power (Smoke): 24 VDC nominal, filtered, 1.0 A. Refer to the D7022 Series,

D7024 Smoke Detector Compatibility List (P/N: 34445) for compatible smoke detection devices.

Option Bus Power: 12 VDC nominal, 500 mA

Optional Standby Batteries: Two 12 V, in series, ranging from 7 Ah to 40 Ah

Two on-board notification circuits, NAC 1 and NAC 2. These are 24 V outputs for notification

devices with up to 2.5 A capacity, but limited by overall 4.0 A capacity on each circuit.

Wired for standard Class "B", Style Y operation. Use the D7015 Class "B" to Class "A" NAC Con-

verter to convert to Class "A", Style Z as needed.

Configurable for Patterns: Steady, pulsing, ANSI Code 3, synchronized Wheelock, synchronized

Gentex.

Local Relays: The main panel includes two Form "C" relays. The relay contacts are rated at 5 A,

28 VDC. No overcurrent limiting is performed on these relay contacts.The default selection for the

relays is to indicate general alarm and general system trouble. By programming the relays using

point and zone mapping, they can be programmed to activate on a variety of conditions.

D7035 Remote Relay Module: An Octal Relay Module that provides eight Form "C" relay outputs.

It connects to the D7024 through the option bus. The outputs are fully programmable, like the local

relays. Each output operates independently of the other seven to provide complete flexibility. Com-

munication with the D7035 is supervised.

Contact Rating: 5 A at 28 VDC

Number of Modules: 2 units maximum

Wiring Requirements: Refer to Section 4.2 Option Bus Wiring Requirements on page 19.
