Control Panel Installation
4.10.2 Auxiliary Power Installation
NAC Circuits 1and 2 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 2.5A in an alarm condition (total current for system must not
exceed 2.5A in alarm or 1.0A for all other conditions).
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 Section 7.5).
Door Holder Power
Use the Door holder power for fire door applications. When there are no alarms in the system and the panel has AC power, door holder
circuits have 27.4 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.
NOTE: Figure 4.25 uses UL listed door holder Model 1400 from Door Control International as an example.

4.11 On-Board Relays (Conventional)
The control panel has two built-in programmable relays and a built-in trouble relay. All relays are Form C rated at 2.5 A @ 27.4 VDC
Resistive.
NOTE: The N.C. contact is the relay contact that is closed when the panel has power and there are no alarm or trouble conditions
4.11.1 Common Trouble Relay
The control panel has a dedicated Form C trouble relay built into terminals labeled TROUBLE. The relay provides a normally open and
a normally closed contact. The trouble relay will deactivate under any trouble condition. Form C rated at 2.5 A @ 27.4 VDC Resistive.
4.11.2 Programmable Relays
The control panel has two Form C programmable relays built into terminals labeled RELAY 1 or RELAY 2. Each relay provides a nor-
mally open and a normally closed contact.
To install one or two programmable relays, follow these steps.
1.
Wire Relay 1 and/or Relay 2 as needed for your application. See Figure 4.26 for the location of the relay terminals.
2.
Configure the relay through programming (see section 7.2).

Figure 4.25 Example of an Auxiliary Power For Door Holder
Use AC power, the door holder circuits have 27.4 volt power present at their terminals.
Use constant power for applications that require a constant auxiliary power source. Power is always
present at Constant circuits.
Resettable power is typically used to power beam detectors, flame detectors and conventional 4-wire
smoke detectors. For circuits selected as Resettable, 27.4 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 continuously outputs the System Sensor synchronization pattern and is
intended for use with B200S sounder bases.
