*NOTE: When a unit is powered at the 120VAC or 220/240VAC input, any combination of accessories may be used such that the given accessory loads are:

60 mA or less in the standby state; 110 mA or less in the alarm state.

[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 DH100ACDCP 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 9; wire runs must be limited to 25 ohms or less per interconnecting wire.

Please note that the magnetic coil supplied with the RTS451 and RTS451KEY is not required when these accessories are used with the DH100ACDCP detectors.

The functionality of the magnetic coil has been designed into the circuitry of the new Innovair™ duct smoke detec- tors.

[6.2.2.3] SSK451 Multi-Signaling Accessory

The System Sensor SSK451 Multi-Signaling accessory combines 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 12.

[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 Boards

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 loosen and blow out any remaining debris. Replacement screens (S08-39-01) are available.

3.Vacuum photo chamber, then use clean compressed air to blow area clean.

4.Replace the chamber by pressing it onto the base. Press the screen into place. It should fit tightly on the chamber.
