System Sensor DH200RPL Sampling tube filter installation, Wiring Instructions, Install The Cover

NOTE: Air currents inside the duct may cause excessive vibration, especially when the longer sampling tubes are used. In these cases a 3 inch (75mm) floor flange (available at most plumb- ing supply stores) may be used to fasten the sampling tube to the other side of the duct. When using the flange/connector mounting technique, drill a 1-inch to 11⁄4-inch (25 to 32mm) hole where the flange will be used.

[5] Install The Filters

To install the sampling tube filters, simply push the filters into the sam- pling and exhaust tube holes, as shown in Figure 6. If a metal sampling tube is used, install the filters into the tube end.

CAUTION

Filters require periodic cleaning or replacement, depending on the amount of dust and dirt accumulated. Visually inspect the filters at least quarterly; inspect them more often if the dust accumulation warrants it. See Section [9.1.2] for more information. Replacement filters can be ordered (filter P/N F36-09-11).

[6] Field Wiring Installation Guidelines

Two LEDs on each duct smoke detector may light, if programmed by the system control panel, to provide a local, visible indication. Remote LED annunciator capability is available as an option. Each duct smoke detector can only be wired to one remote accessory.

Different panel manufacturers offer different feature sets across their dif- ferent panel models. As a result, certain features of the DH200RPL may be available on some control panels, but not on others. The possible features available in the DH200RPL, if supported by the control panel are:

1.Panel controls the LED operation on sensor. Operational modes are RED blink, RED continuous, and off.

2.The remote output of the RA400Z does not follow the condition of the duct smoke detector LED while in standby. When in alarm, the LED output of the detector and remote will be identical.

Please refer to the operation manual for the UL

listed control panel for specific operation of the DH200RPL.

Wiring Instructions

Disconnect power from the communication line before installing the DH200RPL duct smoke detector.

Wire the DH200RPL duct smoke detector per the Control Panel Installation Manual and Figures 9, 10 or 11.
