| CAUTION: Do not remove pull pin at this time. Refer to Page 14, FIGURE 22 for this step AFTER system check-out.
SYSTEM CHECK-OUT AFTER INSTALLATION
After aiming the spray nozzles and placement of the temperature sensors conduct final system check-out to include operation of the electric or gas shutoff by accomplishing the following:
1. Insure the 9V DC battery is installed in the central processing unit (CPU) board.
2. Observe the red LED beside the battery holder blinks approximately every 45 seconds. This indicates the unit is operating and the battery is good.
3. If the alarm sounds, remove the battery immediately and recheck the connections as shown in FIGURE 3 for one or more of the following:
-
Open or bad connection to the sensors
- Shorted sensor or frayed wires shorting.
- Open or bad connection to the electronic release valve.
4. In the event of a low battery, the alarm will "chirp" approximately once every 45 seconds. The unit is still operational, but the battery must be replaced to assure continued, uninterrupted operation.
SHUTOFF CHECK-OUT
1. Insure the electric or gas shutoff has been installed in accordance with the instruction contained in this manual. See FIGURE 9, Page 8 (Electric) and FIGURE 13, Page 9 (Gas).
2. Electric Stove: Turn on any burner to the high position until burner coil is hot.
Gas Stove: Light any burner and turn to the high position.
3. Locate and remove the positive (+) #2 heat sensor terminal wire connection (red lug) on the central processing unit control board terminal block. SEE FIGURE 3.
4. Once removed, the audible alarm on the CPU control board will activate.
NOTE: Though the audible alarm has activated, extinguisher cylinder release valve will not activate.
5. Allow CPU board audible alarm to sound for approximately 10-15 seconds, which will activate either the electric or gas shutoff.

6. Check that the electric or gas shutoff has activated by observing the following:
Electric Stove Shutoff Unit: Burner coil heat has decreased and all electrical power to the stove has been shut off, i.e. stove power light is off. Turn burner to OFF position. Reset the electric shutoff unit as outlined on Page 8.
Gas Stove Shutoff Unit: Burner is no longer lit and all gas to the stove has been shut off, i.e., other burners cannot be lit. Turn burner to OFF position. Reset the as shutoff unit as outlined on page 9.
7. Once the shutoff (electric or gas) has activated, reconnect the positive (+) #2 heat sensor terminal wire connection (red lug) to the CPU board terminal block. See FIGURE 3, Page 5. Once reconnected the CPU board audible alarm will cease to sound and the CPU board will automatically reset itself. Observe that the red LED light beside the battery holder blinks approximately every 45 seconds once again. This indicates the CPU board has reset itself and the unit is operating.
CAUTION: If the Guardian III Model
G300-A fails to operate as described in items 1 - 7, contact the company the unit was purchased from or Twenty First Century for an authorized Twenty First Century service center for assistance.
SOLENOID RELEASE VALVE AND AUXILIARY OUTPUT
1. Insure 9-volt battery is installed and the safety pull pin is still engaged.
2. Use a wire and create a short across one of the sensor terminals (P1 - 1 & 2 or 3 & 4). REMAIN SHORTED UNTIL STEP 5!
Note: DO NOT REMOVE a sensor wire. This enables the FAIL SAFE mode. Sensor must have a short across the terminals to simulate a FIRE DETECT MODE.
3. Verify that the release valve solenoid is activated. See FIGURE 22.
NOTE: While the CPU board audible alarm is activated, observe that the red LED light is blinking approximately once per second.
4. While the alarm is being activated, use a continuity checker and verify that approximately every 10 seconds the auxiliary contacts on P1-5 (COM) and P1-6 (N/C) switch. Verify P1-5 (COM) and P1-7 (N/O) switch.
5. Remove the short across the sensor terminals. System alarm stops (Fire Detect Mode Disabled).
6. Position valve handle and engage solenoid release latch. See "ARMING YOUR SYSTEM." See page 14 Figure 22. |
