H0160-00

Trouble — If the detector LED does not flash, then the detector lacks power (check wiring, panel, or power supply), the detector board is miss- ing (replace), the cover has been missing or not secured properly for more than 7 minutes (secure cover properly), or the unit is defective (return for repair).

Test — The trouble condition can be caused intentionally to verify correct operation of the system. Remove the detector board to cause a trouble condition locally and at the system control panel.

Cover

Tamper — If the cover is removed or not properly secured for a period longer than 7 minutes, a trouble signal is generated to indicate the cover is missing.

[6.2.2] Alarm Tests

[6.2.2.1] M02-04-00 Magnet Test

1.Place the painted surface of the magnet onto the TEST locator on the bottom of the housing (Figure 14).

2.The red alarm LED on the detector should latch on, as should any accessories (i.e. RA400Z, RTS451). Verify system control panel alarm status and control panel execution of all intended auxiliary functions (i.e. fan shutdown, damper control, etc.).

3.The detector must be reset by system control panel, front cover reset button, or remote accessory.

[6.2.2.2] RTS451/RTS451KEY Remote Test Station The RTS451/RTS451KEY Remote Test Station facilitates test of the alarm capability of the duct smoke detec- tor as indicated in the RTS451/RTS451KEY manual. The DH100ACDCLP duct smoke detector can be reset by the RTS451/RTS451KEY. If a system control panel is used, the panel itself may also require testing.

To install the RTS451/RTS451KEY, connect the device as shown in Figure 10; wire runs must be limited to 25 ohms or less per interconnecting wire.

NOTE: Wiring diagram shown is for DH100ACDCLP 4-wire duct smoke detector system equipped without a control panel.

Please note that the magnetic coil supplied with the RTS451 and RTS451KEY is not required when these accessories are used with the DH100 Series detectors. The functionality of the magnetic coil has been designed into the circuitry of the new Innovair™ duct smoke detectors.

[6.2.2.3] SSK451 Multi-Signaling Accessory

The System Sensor SSK451 Multi-Signaling accessory com- bines a sounder feature with a key activated test and reset function. Green, amber and red LEDs provide a visual indication of power, trouble, and alarm respectively. An optional strobe (PS24LO) with a smoke lens can be added to conform to the codes of certain jurisdictions.

To install the SSK451, connect the device as shown in Figure 13.

[6.2.3] Sensitivity Tests

[6.2.3.1] MOD400 or MOD400R Test

After verification of alarm capability, use the MOD400R test module with a voltmeter to check detector sensitivity as indicated in the test module’s manual. The housing cover must be removed to perform this test.

If test module readings indicate that the detector head is outside of the acceptable range that is printed on the label of the detector, the detector chamber requires cleaning per Section [7] of this manual.

[7] Detector Cleaning Procedures

Notify the proper authorities that the smoke detector sys- tem is undergoing maintenance, and that the system will temporarily be out of service. Disable the zone or system undergoing maintenance to prevent unwanted alarms and possible dispatch of the fire department.

[7.1] Air Filters

1.Turn off power to the system.

2.Remove and inspect sampling tube filters.

3.If filters are heavily coated with dirt, replace them with new filters. If they are not heavily coated, use a vacuum cleaner or compressed air nozzle to remove dust, then reinstall the filters.

[7.2] Photo Detector Board

1.Remove the screen by gently grasping on each side and pulling straight off.

2.Lift the photo chamber in the same fashion. Vacuum the screen and cover. Use clean, compressed air to

DH100ACDCLP specifications

The System Sensor DH100ACDCLP is a cutting-edge addressable heat detector renowned for its advanced features and reliability in fire safety systems. Designed to meet various application requirements, this device excels in environments prone to false alarms while ensuring efficient fire detection.

One of the DH100ACDCLP’s main features is its advanced thermal sensing technology. This device utilizes a combination of fixed temperature and rate-of-rise sensing methods, allowing it to accurately detect abnormal heat levels in its surroundings. The fixed temperature feature triggers an alarm when the ambient temperature exceeds a predetermined threshold. Meanwhile, the rate-of-rise detection monitors rapid temperature increases, making it ideal for applications like kitchens, attics, and mechanical rooms where combustibles may not be immediately visible.

The DH100ACDCLP also incorporates an innovative addressable technology. This allows the device to communicate directly with the fire alarm control panel, providing precise location information and reducing response times during emergencies. By having each detector uniquely identified, facility managers can easily pinpoint which unit has triggered an alarm, streamlining response and ensuring the right areas are addressed swiftly.

Another notable characteristic of the DH100ACDCLP is its robust design, capable of operating in a variety of challenging environments. The unit is built to withstand temperatures ranging from -40°F to 150°F (-40°C to 66°C), making it suitable for both indoor and outdoor installations. Its resilient construction ensures longevity and durability, which is crucial for maintaining reliable fire safety measures over time.

Moreover, the DH100ACDCLP is compliant with various safety and performance standards. It obtained listings from UL and other recognized certification bodies, ensuring it meets strict criteria for fire detection capabilities. This compliance reinforces its credibility and effectiveness in safeguarding lives and property.

In addition to its technical features, the DH100ACDCLP is designed for straightforward installation and maintenance. Its user-friendly interface allows both installers and end-users to navigate settings and conduct routine checks with ease, ensuring that the system remains functional and reliable.

In summary, the System Sensor DH100ACDCLP stands out as a sophisticated heat detector, combining innovative thermal sensing technologies with an addressable communication system. This ensures precise detection, rapid response, and adaptability to various environments, all while maintaining compliance with safety standards. It is an indispensable component of modern fire detection systems, providing peace of mind to property owners and facility managers alike.
