Door Holder Application

In a typical door holder application, the door holder power must be interrupted to close all fire doors under the
following conditions:
• Any active alarm condition.
• AC power failure (to conserve battery power).
To close the fire doors in these situations, wire an N.C. programmable relay from the FACP in series with the
auxiliary power to the door holders as shown in Figure 5-7.
The circuit shown in Figure 5-7 will provide up to 3 amps of door holder power. (See Section 5.2 if you need
more than 3 amps of auxiliary power.) The power in this example is released when AC power is off for 30
seconds or more, or when the relay from the fire alarm control panel becomes open. You would have to use the
equivalent of a programmable relay from a fire alarm control panel that is programmed to open under alarm
conditions. See Section 4.8.4 for selecting auxiliary power options.

Troubleshooting

Light-emitting diodes (LEDs) indicate fault conditions. This section describes the LED states.
6.1

LEDs

The eight LEDs indicate a fault in one of the circuits (either NACs 1 through 4, auxiliary power, earth fault, low
AC, or battery). A fault in the LED's corresponding circuit will light the LED (labeled on the board). Their
functions are as follows:
LED Color
OUT1 Yellow
OUT2 Yellow
OUT3 Yellow
OUT4 Yellow
AUX Yellow
FLT Yellow
