Note: The Master - Slave application is used to save on popit addresses for a large systems. You can use one popit address for a long hall or one large room that would otherwise require several addresses to cover it. 1. The F220-B6PM is a 24 VDC 4-Wire Master Popited Base that supervises up to nineteen F220-B6 Two-Wire Slave Bases. The two-wire slave detectors then report as the master base address. 2. The F220-B6PS 4-Wire Popited Base operates on 12 or 24VDC that does not support 2-Wire Slave bases. 3. The F220-B6PS, F220-B6, and the F220-B6PM bases can use any of the following smoke or heat heads. F220-P - Photoelectric Smoke Detector F220-PTH - Photoelectric Smoke Detector with 135F/57C Heat Sensor F220-PTHC - Photoelectric Smoke Detector with 135F/57C Heat and Carbon Monoxide Sensors F220-135 - Electronic Rate of Rise/Fixed Temperature 135F/57C Heat Detector F220-135F - Electronic Fixed Temperature 135F/57C Heat Detector F220-190F - Electronic Fixed Temperature 190F/88C Heat Detector
The FLM-7024-ISO MUX bus isolator module is placed between devices on the MUX bus. A short on the bus causes activation of the isolators adjacent to either side of the short. This effectively separates all devices between the activated isolators from the rest of the bus. This prevents failure of the entire bus. When the short condition is removed, the isolators automatically restore the entire loop to normal operation.
One of the zones at the panel is in constant trouble.
Need to have proper wiring connections. Check the following:
1. Using 12 Volt Smokes, Terminal 1 goes to Terminal 8 on the panel Switched AUX Power.
2. Make sure D136 relay is installed for Relay C for non G-Series panels.
3. For 24 Volt Smokes, Terminal 1 goes to a D130, and a UL 24 Volt PSU is needed on Terminal 8 on the Panel. Switched AUX Power goes to the D130 to reset the 24 Volt power.
4. Measure the EOL across loop "A" Terminals 7 and 9 of the D125B card. Look for 1.8K Ohms for the D125B on a new install or when adding to an existing install. If replacing a D125 or D125A the EOL would be 1.5K Ohms.
5. Measure the EOL across loop "B" Terminals 6 and 8 of the D125B card. Look for 1.8K Ohms on the D125B card on a new install or when adding to an existing install. If replacing a D125 or D125A the EOL would be 1.5K Ohms.
6. Measure the Voltage across Loop "A" Terminal 3 and Terminal 4 on the D125B card. The meter should read 2.5VDC with everything connected. If the reading is 5VDC the loop is Open (not seeing the 1.8K EOL across the last Smoke. If the voltage reading is Less than 1VDC you have a Short on the loop. The short could be a smoke head latched in alarm, bad/dirty smoke head, wiring short, or reversed polarity to one of the smoke heads on the loop.
7. Measure the Voltage across Loop "B" Terminal 2 and Terminal 4 on the D125B card. The meter should read 2.5VDC with everything connected. If the reading is 5VDC the loop is Open (not seeing the 1.8K EOL across the last Smoke. If the voltage reading is Less than 1VDC you have a Short on the loop. The short could be a smoke head latched in alarm, bad/dirty smoke head, wiring short, or reversed polarity to one of the smoke heads on the loop.
To verify the D125B is working correct you can wire the 1.8K Ohm EOL accross termainals 7 & 9 and another 1.8K Ohm EOL accross termainals 6 & 8.
The Loop termainals 2 & 3 need to wire to the Positive Side of a 1K Ohm Zone. The EOL for the 1K Ohm zone is built in to the D125B.

What are the proper steps in cleaning a DS200HD smoke head?
Turn off all electrical power to the detector.
Depress the tab on the two sides of the detector adjacent to the LED, and pull the unit from its base.
Fill three (3) clean buckets each with 1-1/2 gallons normal tap water.
NOTE: De-ionized or distilled water is preferable in areas where hard water with large mineral content is prevalent.
Add one (1) teaspoon of dishwashing liquid (Ivory Dishwashing liquid only) to the first bucket and mix thoroughly, then place the dirty detector into the soapy water until it is completely submerged. Allow the unit to soak for approximately ten (10) minutes, then agitate to insure all dust and dirt is removed.
Remove the unit to the first clean water bucket, submerge detector and agitate for 5-10 seconds to remove all soap residue.
Finally, move unit to the second clean water bucket, and repeat the procedure in step #5. Remove from second bucket, then vigorously (not violently) shake unit to drain all water. Remove unit to dry area and allow to drain and dry by resting unit on its side. Allow unit to dry for a period of 72 hours before use.
Air Dry units only.
Do not use any hot air device or attempt to place unit in oven, as this will result in damage to the detector. Also wash and rinse water should be changed every 5-7 units to maximize the results.
My panel is displaying a trouble "Internal Fault" on a smoke detector
"Internal Fault" on a smoke means the device couldn't be calibrated by the panel.
Clean the device by following the instructions below.
Replace the head and send the defective head in for recalibration or replacement to the National Repair Center at 800-289-0096 x2220.
Cleaning the D323A or D324A
Remove and disassemble the sensor
Follow the steps in this section to prepare the sensor for cleaning:
Remove the sensor from its base.
Disassemble sensor by following the NSRT-A100 instructions found at the end of this page.
Note: The NSRT-A100 is a Hochiki part number and can be ordered by calling Hochiki sales support at 714-522-2246 or Hochiki technical support at 800-845-6692
Clean the sensor
CAUTION: Do not attempt to remove the insect screen. Follow the steps in this section to prepare the sensor for cleaning:
Remove the Outer Cover of the sensor as specified on page 5 and set aside.
Place the sensor in the palm of your left hand and grasp the Chamber Cover with your right hand. Twist the Chamber Cover counter clockwise until the Cover Tabs clear the Tab Catches. Lift and separate the Chamber Cover from the Optical Unit.
Swab the Optical Unit with denatured alcohol using a small soft bristled brush.
Use dry clean compressed air to dry the optical unit and to remove any remaining particles.
Clean the Chamber Cover and Outer Cover in the same manner.
Reassemble the sensor.
Follow the steps in this section to reassemble the sensor.
Locate the Alignment Arrows on both the Chamber Cover and the Optical Unit.
Set the Chamber Cover onto the Optical Unit while making sure the Alignment Arrow 1 and Alignment Arrow 2 are aligned with one another.
Holding the sensor in your left hand and grasping the Chamber Cover with your right hand, rotate the Chamber Cover clockwise until the Cover Tabs snap into the Tab Catches.
Place the Outer Cover of the sensor nose down on a flat surface.
Align the Outer Cover Keys with the Recess in the Outer Cover (two orientations are possible, only one will fit properly).
With the Outer Cover Keys aligned with the Cover Recessed, press down firmly on the back of the sensor. The sensor will snap into the Outer Cover. The sensor is now ready to be returned to the base from which it was removed.
The sensor should be re-tested by following the test procedure found in the control panel literature.
NOTE: If after testing, the sensor is not working within the prescribed range then return it to the manufacturer for servicing.
Sensor Cover Removal Instructions
This section explains how to remove the outer cover from the D323A and D324A by using the NSRT-A100.
Remove and disassemble the sensor
Follow the steps in this section for removal of the sensor cover:
Place the sensor to be disassembled on the NSRT-A100 tool making sure that the Locator on the sensor is aligned as shown on the diagram.
Using your thumb and index finger rotate the sensor back and forth until it drops into place on the NSRT-A100.
Grasp the sensor firmly and rotate the sensor clockwise (approximately 30 deg.) until the Locator on the sensor lines up with the Mounting Ears of the NSRT-A100. The contact blades on the sensor will engage on the NSRT-A100 and will prevent further rotation.
The sensor cover is now disengaged from the sensor body and can be removed by pulling the sensor cover away from the NSRT-A100.
After the cover has been removed, refer to the sensor cleaning instructions to clean and reassemble the sensor.
