N/O
Detector
Trouble
Yellow
(LED 6)
If lit, indicates a trouble condition (open) within the N/O 2-wire (or 4-wire) smoke detector loop (emanating from terminal
board positions 3 and 4), resulting from either incorrect wiring or incorrect placement of the end-of-line resistor, and the
smoke detector loop is inactive. Refer to the Smoke Detector Installation section of this manual for correct wiring
instructions (Figures 3-5).
N/O
Detector
Alarm
Red
(LED 5)
If lit, indicates that the N/O 2-wire (or 4-wire) smoke detector loop (emanating from terminal board positions 3 and 4)
is in alarm. When lit during testing, press the Auxiliary Reset Button at the bottom of the release device to reset the loop
(Figures 3-5).
N/C
Detector
Trouble
Red
(LED 4)
If lit, indicates an open circuit within the N/C 4-wire smoke detector loop (emanating from terminal board positions 5 and
6), resulting from either incorrect wiring or incorrect placement of the end-of-line relay or the detector(s) are in alarm.
If in alarm, cycle power off and then on to the smoke detectors to reset, then depress the auxiliary reset button to reset
the release device. Refer to the Smoke Detector Installation section of this manual for correct wiring instructions
(Figures 6 and 7).
Close Door
Detection
Green
(LED 2)
If lit, indicates that the fire door or shutter is closed and activating the proximity switch. If not lit, refer to the Close Door
Detection section of this manual for correct wiring instructions (Figure 8).
Annunciator
Trouble
Yellow
(LED 9)
If lit, indicates a trouble condition (open) within the annunciator loop (emanating from terminal board positions
9 and 10), resulting from either incorrect wiring or incorrect placement of the end-of-line resistor. Refer to the Annunciator
section of this manual for correct wiring instructions (Figure 10).
Ground Fault
Yellow
(LED 3)
If lit, indicates that one of the ancillary devices/loops (smoke detector, annunciator, etc.) is not grounded properly, and a
short to earth ground exists.

OPERATIONAL CHECKLIST
POWER
Is the red LED, labeled “Power,” located on the bottom of the
enclosure lit?
CHECK THE ALARM
Are the alarm (smoke detection) inputs correct? If not, the
release device will not release the fusible link assembly in a fire
condition. Conversely, the release device will always release the
fusible link assembly when powered or reset.
CIRCUIT BOARD DIAGNOSTIC LEDS
View diagnostic LEDs present on the circuit board located behind
the terminal block (See Wiring Diagram). Refer to the table below
for the status LED indications.
Is the Red LED Lit?
Yes
Move on.
No
Check power connections per Wiring Diagram.
Check voltage; voltage should be 120Vac, 24Vac or 24Vdc
connected as part of the wiring diagram.
Are the Alarm Inputs correct?
Yes
Move on.
No
Check that it is a dry contact input. There should not be any
voltage on the alarm lines when they are disconnected from the
unit.
Verify that all wiring is per manufacturers’ instructions.
CHECK THE CLOSE DOOR DETECTION
Is the Yellow LED on the bottom of the enclosure lit? If lit, the
close limit detection input is active, the devise is disabled and will
not perform a mechanical release.
CHECK THE BATTERY CONNECTIONS
Is the Green LED on the bottom of the enclosure lit? If so, the
battery is connected properly. If the LED does not light, the
battery is not functioning properly and a trouble sounder will
annunciate. Check the following:
1. Are the battery leads properly connected or do the leads
have a defective connector?
2. Do the battery connections observe correct polarity —
Red (+) and Black (–)?
3. Is the battery discharged? If so, allow 10 minutes for the
battery management system to recharge the battery. If the
sounder does not stop after this time, then the battery needs
to be replaced. Refer to the “Replacement Parts and
Accessories” section of this manual for ordering instructions.
Battery Performance Inconsistencies
- Does the unit go into
alarm and release the fusible link as soon as power is applied? If
so, then check the wiring and connections on the smoke detector
loop, focusing especially on the presence and the correct
placement of the end-of-line resistor. Also, if N/O smoke
detectors are being used, make certain that the Wire Jumper
between positions 5 and 6 on the release device’s terminal strip
is in place.
