CHECKFIRE 110
Detection and Actuation System
TABLE 6-4: OPERATIONAL TEST
The following tests verify system operation for:
1. Circuit Supervision: Confirm supervisory function of each
circuit.
2. Detection Input: Receive electrical signal from a detection
device (simulated fire condition).
3. Time Delay: Verify accuracy of time delay setting.
4. Spot Thermal Detectors: Verify contact closure.
5. Electric Manual Activation: Receive electrical signal from
an EMA.
If noted results are not attained, refer to Section 9 -
Troubleshooting for corrective action.
NOTICE
If the system is connected to a vehicle shut-
down device through the pressure switch,
verification needs to be made at the pres-
sure switch.
NOTICE
During testing, verify any devices connected
to the Alarm Circuit Lead function as
intended.
Detection Circuit - Supervision Test
Set DCT switch to “Fault” position. The CHECKFIRE 110
Control Module indicates the following:
1. Detection Fault LED pulses AMBER 1 x 10 seconds.
2. Sounder pulses 1 x 10 seconds.
Test silence function: push the “DELAY/Reset/Silence”
button.
3. Sounder silences and Detection Fault LED continues to
pulse AMBER 1 x 10 seconds.
Reset the DCT to the “Normal” position.
4. CHECKFIRE 110 Control Module returns to Normal
status; Power LED is GREEN steady-on.
CAUTION
Before performing any operational test(s), protect the fire
suppression system from unintentional actuation. Verify
Electric-Pneumatic Actuators are not connected to Release
Circuit Drop Cables and any pneumatic manual actuators are
ring-pinned for safety and/or actuation cartridges removed.
CAUTION
When performing any operational testing, make certain the
RCT (Part No. 441021) and Release Circuit Test Plug(s) (Part
No. 440912) are attached to the release circuit.
