FIRE DETECTION COMPONENT TESTING

1. Activate an ionization smoke detector or a thermal fire detector (WP 0017 00).

2. Refer to figure 1 for the fire detection system equipment location diagram while verifying that the following

indications occur after activating the detector:

a. The proper ZONE Light Emitting Diode (LED) indicator (figure 2, item 1) illuminates on the dual zone

module (figure 2, item 2).

b. On the CP-35 control panel (figure 2, item 3), ensure that the system POWER indicator (figure 2, item 4)

is illuminated while the system ALARM (figure 2, item 5), system TROUBLE (figure 2, item 6), GROUND

FAULT (figure 2, item 7), and AUDIBLE CIRCUIT (figure 2, item 8) trouble LED indicators are off.

3. Deactivate the ionization smoke detector or thermal heat detector (WP 0017 00) and ensure that the ZONE

LED indicator that illuminated in step 2 extinguishes.

4. Open the fire and smoke detection panel door (figure 2, item 9).

5. Set the RESET LAMP TEST switch (figure 3, item 1) on the CP-35 control panel (figure 3, item 2) to the

RESET position.

6. Ensure that all the visual indicators (figure 2, items 4, 5, 6, 7, and 8) on the CP-35 control panel (figure 2,

item 3) illuminate, and the trouble horn sounds when the RESET LAMP TEST switch (figure 3, item 1) is

moved momentarily to the RESET position.

7. Return the RESET LAMP TEST switch to the normal position and verify that the indicators and horn that were

activated in step 6 are now OFF.

8. Return the equipment to the desired readiness condition.
