Required Maintenance and Testing
Keep the detector calibrated for proper operation. NFPA 72, The National Fire Alarm Code, recommends performing calibration tests at installation, then every other year. Depending on local regulations, calibration testing might be required more than once a year. Perform functional testing yearly.

NOTE! Notify all concerned parties before any maintenance or testing of the fire alarm system and upon completion of these activities.

Test the calibration (to meet NFPA 72) using either the magnet test or measuring the calibration with a calibrated product from No Climb Products Ltd. Quickly determine the calibration by a visual inspection of the detector’s LED (refer to Section 4.4 Flash Rate and Trouble Indication on page 22). These tests confirm whether or not the detector is within its factory marked calibration range. At least once a year vacuum or wipe the external part of the detector clean. Pay particular attention to the detector screens in areas of heavy insect activity or dust. To clean the chamber, use a can of clean, dry compressed air (such as TECHSPRAY ENVI-RO-TECH Duster) which is available at office and alarm supply stores. Shorten the plastic tube that comes with the compressed air to about 2 in. (5 cm). Place the tube or needle valve through the Chambermaid valve in the bottom of the detector (refer to Figure 2.2 on page 7).

NOTE! Do not paint the detectors. Paint or other foreign matter covering the detector can prevent smoke detection.

F220 Series Heat Detector Heads

The F220 Heat Detector Heads can be identified by color coding (refer to Table 2.2).

WARNING! The F220-135, F220-135F and F220-190F are not life safety devices. Use them with F220-B6 Series bases to provide general property protection.

F220 Series Smoke Detector Heads

The F220 Series Smoke Detector Heads are UL Listed, openarea photoelectric smoke detectors that work with commercial fire protective signaling systems and household fire warning systems. Select the appropriate mounting base to configure the detectors for two-wire or four-wire versions (refer to Section 2.1.2 Base Comparisons on page 4).

To verify power to the detector and a functioning smoke sampling circuitry, a dual color LED indicator flashes green every eight seconds when operating normally. It flashes once every four seconds when a trouble condition exists. If the detector determines an alarm condition exists, the LED changes from flashing green to steady red. The detector returns to normal when power is interrupted and the alarm condition clears.

Throughout its normal life cycle, the smoke detector monitors and periodically adjusts itself to keep the sensitivity at its factory calibrated level. When excessively dirty, the detector’s LED flash rate changes from an eight second flash rate to a four second rate. If CleanMe is selected, the detector sends a CleanMe signal to the compatible control panel to indicate a dirty smoke detector. Refer to Section 4.3 Set CleanMe Feature on page 22

Electrical Supervision

When the F220-B6 Series Bases are wired according to the instructions in this document, the control panel initiates a trouble signal when a detector is removed from its base, providing tamper protection. An EOL power supervision module, such as a D275 or an F220-B6E Power Supervision Base and an EOL resistor as specified by the control panel manufacturer, supervises power.

Install the Bases

Mount the Bases

With the exception of the F220-B6E base, all four-wire bases can be used in any combination within a loop. One F220-B6E  Power Supervision Base can be used as the last base on a loop in four-wire systems to provide power supervision.

NOTE! Follow NFPA 72 guidelines for mounting locations. For commercial and industrial installations, 30 ft (9 m) spacing between smoke detectors is recommended.

1. Release the mounting skirt from the mounting base. Use a screwdriver at the location of the snap locks (refer to Figure 2.1, item 12, page 5) to release the mounting skirt.

2. Run all system wiring (refer to Section 3.2 Wire the Bases).

3. Mount the base using the two oblong mounting holes. Fits 4 in. square, octagon, AB, and single-gang back boxes.
   NOTE! Depending on local regulations, you can surface mount the bases using anchors, mollies, or wing nuts, or you can mount directly on back boxes.
   NOTE! The electrical box must be large enough to accommodate the number and size of conductors specified by the National Electrical Code or any local authorities having jurisdiction (AHJ).

4. Tighten the base to the mounting surface. Tighten until snug, but not distorted.

Wire the Bases

CAUTION! When wiring bases, all terminal screws including those not wired must be tightened to prevent loose screw heads from making intermittent electrical contact with the detector head.

Terminal Connections

WARNING! Do not twist or loop the wires around the terminals. In and out wires for terminal connection must be cut, stripped, and inserted as individual ends.

NOTE! Bring the positive (+) wires in on terminal b2 and out from terminal b1. Use a consistent pattern, inputting on b2 and outputting from b1. The negative (-) wires input and output from the same terminal (a1/a2).

EOL Resistors
Use the EOL resistors supplied or specified by the control panel manufacturer. This applies to all loop terminations including the D275 Module and the F220-B6E Power Supervision Base.

Loop Wiring Specifications
In a two-wire system, the maximum loop length depends on the number of F220-B6 bases on the loop, the wire size, and the control panel specifications. Refer to the control panel’s installation instructions for specific wiring information. In a four-wire system, the maximum loop length and number of bases that can be placed on a loop depend on the voltage drop on the power circuit. Use standard voltage drop calculations to ensure that the last detector on the loop meets the minimum voltage requirement of at least 10 V.

Four-wire Loop Termination
One D275 End-of-Line Module (refer to Figure 3.6 on page 17) or F220-B6E Power Supervision Base (refer to Figure 3.4 on page 15) is required for each loop when using four-wire bases.

Wire Optional Remote Annunciators
If using the optional DRA-5 Remote Alarm Indicator, connect the positive (red) wire to terminal b1 and the negative wire (white) to terminal c (refer to Figure 3.1).

1. Red wire to Terminal b1 on base
2. White wire to Terminal c on base

CAUTION! The mounting skirts and detector heads are keyed. Do not force them onto the mounting bases

Install:
Install the detector head by lining up the LED on the detector head (refer to Figure 4.2, Item 6 on page 19) with the bar on the mounting skirt (refer to Figure 4.2, Item 7). Turn the detector head clockwise until the LED aligns with the T mark on the mounting skirt (refer to Figure 4.2, Item 8).

Remove:
Remove the detector head by turning it counter-clockwise. If the optional locking bar is used, refer to Figure 4.3.

1. Insert screwdriver through the locking port and depress the locking bar.
2. Hold the locking bar down while turning the head counter-clockwise until disengaged.

Set Detector Modes

The F220 Series Smoke Detectors feature a unique magnet-operated sensitivity mode and detector test mode.

Test Mode
Test the detector by placing the magnet next to the T mark on the mounting skirt (refer to Figure 4.2, Item 8 on page 19) for three consecutive flashes to cause an alarm.

Sensitivity Mode
If the magnet is next to the T mark for less than three flashes but more than one flash, the detector enters Sensitivity Mode.

1. Place the detector into Sensitivity Mode.
2. Wait for the first single green LED flash.
3. Count the number of red LED flashes that follow and refer
   Number ofRed Flashes| Sensitivity Definition (% Obscuration)
   ---|---
   1| Malfunctioning smoke or heat detector
   3| Normally operating smoke or heat detector withlittle or no dirt contamination
   4 to 6| Progressively more contamination
   7 to 10| Trouble condition, very dirty but stillcompensated to 3%/ft (3%/ft = 0.433 db/m); Sensitivity < 3%/ft at 10 flashes.
   11| Sensitivity < 2.5%/ft (2.5%/ft = 0.36 db/m)
   12| Sensitivity < 2.0%/ft (2.0%/ft = 0.287 db/m),chance of false alarm increases
   13| Sensitivity < 1.5%/ft (1.5%/ft = 0.214 db/m)
   14| Sensitivity < 1.0%/ft (1.0%/ft = 0.143 db/m),chance of false alarm greatly increases
   15| Sensitivity < 0.5%/ft (0.5%/ft = 0.071 db/m),false alarm likely
4. The detector exits sensitivity mode and returns to one green LED flash every eight seconds.

Set CleanMe Feature

The Clean Me feature monitors the smoke chamber’s sensitivity and sends a trouble signal to the control panel when the sensitivity degrades to a preset level.

NOTE! When a CleanMe signal is sent to a control panel that is not CleanMe compatible, the signal may be misinterpreted as an alarm.

To activate the CleanMe feature:

1. Put the detector into sensitivity mode by placing a magnet next to the T mark on the mounting skirt (refer to Figure 4.2, Item 8 on page 19). Remove the magnet after the first red LED flash and before the third red LED flash.
2. When the magnet is removed, the LED flashes green once and shows the first of two sensitivity displays.
3. When the LED next flashes red, replace the magnet near the T mark(refer to Figure 4.2, Item 8 on page 19).
4. Hold the magnet against the T mark on the mounting skirt (refer to Figure 4.2, Item 8 on page 19) until the green LED flashes twice and the red LED repeats the sensitivity indication.
5. The detector exits sensitivity mode. If CleanMe has been successfully enabled, the green LED flashes twice in rapid succession every eight seconds indicating that CleanMe is activated.

To disable CleanMe, repeat this process and verify the double flash returns to a single flash.

Flash Rate and Trouble Indication

These detectors include the Chamber Check Automatic Trouble Indicator that verifies the detector’s calibration is within the factory listed range. NFPA guidelines for sensitivity testing can be met by visually inspecting the detector and checking the flash rate of the LED.

NOTE! Perform the visual check before resetting power. After a reset the trouble indicators clear for 70 seconds. After 70 seconds, if the detector is in a trouble condition, trouble indications begin again.

A unit with CleanMe activated double flashes (two flashes within a half second of each other) every eight seconds. A normally operating unit flashes once every eight seconds. If a detector is in a trouble condition due to a dirty lens or a sensor malfunction, it single or double flashes every four seconds. If enabled, the CleanMe trouble signal is sent.

Test the Installation

Inspect the Installation

1. Check the wiring from the control panel to the last head on each run for proper polarity and continuity.
2. Terminate each run with an EOL resistor as specified by the control panel manufacturer.
3. Terminate four-wire runs with EOL power supervision modules or F220-B6E bases.
4. Apply power to the system. Check for alarms and troubles.
5. Note which detectors alarmed (if any), shut down the system, remove alarmed detectors from their bases, and recheck the bases for proper wiring.
6. If the problem persists, determine if the problem is caused by the detector or the base. Replace the affected detectors or bases with known good units.
7. If a system alarm occurs with no detector alarms present, remove all detectors and check the wiring at each base.
8. Check the wiring of each EOL resistor and EOL module.
9. When the system is alarm free, check each detector to ensure that the green LED indicator flashes approximately every eight seconds. This verifies the detector is receiving power and operating properly.

NOTE! If a heat detector LED flashes at a rate of 4 flashes/sec, the detector is either cold (below +32°F [0°C]), out of sensitivity range, or defective. If a smoke detector flashes at a rate of 4 flashes/sec, it is either out of sensitivity range or defective.

Test Each Detector
Test each detector to ensure it causes a control panel alarm. Reset the control panel after each test.

Activate an Alarm at Each Detector

To cause heat detectors to alarm either:

• Activate the internal reed switch by placing a magnet horizontally against the T mark on the mounting skirt (refer to Figure 4.2, Item 8 on page 19) and holding it there for three consecutive LED flashes, or
• Expose the thermistor (refer to Figure 2.2, Item 3 on page 7)to a heat source such as a hair dryer or a shielded heat lamp until the detector alarms and the alarm LED lights .

To cause smoke detectors to alarm either:

• Activate the internal reed switch by placing a magnet horizontally against the T mark on the mounting skirt (refer to Figure 4.2, Item 8 on page 19) and holding it there for three consecutive LED flashes, or
• Use a UL Listed aerosol smoke detector tester to simulate an alarm. Follow the instructions provided with the aerosol smoke detector tester.

Reset the Control Panel
When a detector alarms, the red LED indicator activates and latches into the ON position. Clear the alarm by momentarily removing power before proceeding to the next detector.

Test the Alarm Loop

Checkthe voltage across the EOL resistor of each alarm loop to verify wiring losses do not exceed control panel manufacturer’s specifications.

Test CO Sensors

Removing the detector head or resetting the detector’s power places the detector in a special test mode for 15 minutes. If over 35 ppm of CO is applied to the detector within this 15-minute period, the detector must alarm or it is defective.

WARNING! The F220-PTHC detects carbon monoxide (CO) as a component of a fire. Do not use the F220-PTHC as a stand-alone CO detector.

Perform NFPA 72 Required Testing
