5: Auxiliary Power Installation - Honeywell 6820 Manual

Control Panel Installation
3. Smoke power is supplied to the Class A loop as shown below.
NOTE: In programming, any point that uses multiple Flexput circuits are always referred to as the lowest Flexput circuit number used. In this
example, Figure 4.51 uses Flexput circuits 5, 6 together with NAC 4. In programming (4, 5, 6) would be referred to as point 5.
4.17.5 Auxiliary Power Installation
Flexput Circuits 1-6 on the control panel can be used as auxiliary power circuits. The four types of auxiliary power available are:
• Door Holder Power
• Constant Power
• Resettable Power
• Sounder Sync Power
Auxiliary power circuits are power limited. Each circuit can source up to 3A (total current for all Flexput circuits must not exceed 6.0 A).
To install an auxiliary power circuit:
1. Wire the Flexput circuit(s) that will be used for auxiliary power. See Figure 4.2 for location of Flexput circuits. When used as auxiliary
power, terminals labeled "O" are negative, terminals labeled "X" are positive.
2. Configure the auxiliary power output through programming (see Section 8.5).
Door Holder Power
Door holder power is intended for fire door applications. When there are no fire system alarms in the system and the panel has AC power,
door holder circuits have 24 volt power present at their terminals. Any fire system alarm will cause power to disconnect. Power will be re-
applied when the fire system is reset. If AC power is not present, the auxiliary door holder power will be disconnected to conserve the battery
backup. When AC power is restored, power is immediately restored to the door holder circuits.
Use a UL-listed door holder for this application. Refer to the Device Compatibility Document for compatible door holder list.
Constant Power
Use constant power for applications that require a constant auxiliary power source. Power is always present at constant circuits.
Resettable Power
Resettable power is typically used to power beam detectors, flame detectors and conventional 4-wire smoke detectors. For circuits selected
as Resettable, 24-volt power is always present at the terminals unless a fire system reset occurs. If a fire system reset occurs, power is discon-
nected from the terminals for 30 seconds, then re-applied. Refer to the Device Compatibility Document for compatible four wire smoke
detectors.
Sounder Sync Power
Sounder Sync Power continuously outputs the System Sensor synchronization pattern and is intended for use with B200S sounder bases.
