Yellow LED (Release Disabled)
Red LED (Line Power Present)
Green LED (Battery Backup Power Present)
Battery Green If the Green LED is lit, then the battery is connected
properly and charged above the minimum acceptable
level. If the LED does not light, check that the leads are
connected to the battery as shown on the wiring diagram.
Disable Yellow The Yellow LED will light when the door reaches the close
limit and activates a proximity switch attached to terminal
positions 7 and 8 on the release device. This configuration
results in the device not releasing the fusible link
assembly in alarm or power loss situations and should
only be used when the fire door is kept in a constant
closed position. If the LED does not light when the door reaches the close
door detection and activates the proximity switch, then
check that the proximity switch has been activated and
that the switch is set to normally open (N.O.). Check to
make certain that the switch is attached to terminal
positions 7 and 8 on the release device.
Power Red If the Red LED is lit, then the line power is connected and
switched “on.” If the LED does not light when power is applied, check
that power is connected as described in the installation
manual electrical connections.

MAINTENANCE REQUIREMENTS
The release device has no scheduled maintenance requirements.
The unit has been designed and tested for use in dry, indoor
locations. Testing of the unit at least once every 90 days is
recommended, but test intervals shall ultimately be subject to
criteria established by the Authority Having Jurisdiction (AHJ).
FUSE REPLACEMENT PROCEDURE AND REPAIR PARTS
One serviceable fuse, a 3 Amp, 3AG, slo-blo fuse, is required for
proper operation and protection of the circuit board. The release
device is shipped with the fuse in place and two replacement
fuses are provided in a separate parts bag. The fuse is located on
the circuit board near the battery cable connection.
For replacement parts refer to Accessory and Replacement
Parts page.
BATTERY MAINTENANCE/TESTING
No maintenance or testing is required for the battery. An audible
warning tone, generated by the trouble annunciator mounted to
the side of the release device, will sound when the battery is
approaching the minimum operating threshold. This indicates the
need to replace the battery.
For replacement parts refer to Accessory and Replacement
Parts page.
BATTERY DISPOSAL
Spent batteries must be treated as hazardous waste and disposed
of in accordance with State, Local and Federal Regulations.
