Class A Notification Wiring; 2: Auxiliary Power Installation; Door Holder Power; Constant Power - Honeywell 6808 Installation And Operation Manual

Class A Notification Wiring

You must use an appliance from the list of compatible appliances in Appendix A.
To install a Class A notification appliance circuit:
1. Wire the Class A notification appliances as shown in Figure 4.41.
CAUTION: For proper system supervision do not use looped wire under terminals marked + and – of the NAC connectors. Break wire runs to
! provide supervision of connections
2. Configure the circuit for Class A in programming (see Section 9.5).
4.13.2 Auxiliary Power Installation
NAC Circuits 1-4 on the control panel can be used as auxiliary power circuits. The four types of auxiliary power available are:
• Door Holder
• Constant
•

Resettable Power

•

Sounder Sync Power

Auxiliary power circuits are power limited. Each circuit can source up to 3A (total current for all NAC circuits must not exceed 3A).
To install an auxiliary power circuit:
1. Wire the NAC circuit(s) that will be used for auxiliary power. See Figure 3.2 for location of NAC circuits.
2. Configure the auxiliary power output through programming (see Section 9.5).

Door Holder Power

Door holder power is intended for fire door applications. When there are no alarms in the system and the panel has AC power, door
holder circuits have 24-volt power present at their terminals. Any alarm will cause power to disconnect. Power will be re-applied when
the system is reset. If AC power is off for more than 15 seconds, 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.

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 system reset occurs. If a system reset occurs, power is
disconnected from the terminals for 30 seconds, then re-applied.
Sounder Sync Power
Sounder Sync Power continuously outputs the System Sensor synchronization pattern and is intended for use with B200S sounder bases.
