Figure 7 - Connecting the DIS2000 Remote Indicator Plate
NOTE: If connecting a DIS240 Remote Test/Indicator Plate, consult the DIS240 Installation Instructions (P/N: 24171).
7.0SET-UP
Before starting this section, confirm that all connections have been made and are secure, then apply power to both units.
•Press the Aim Mode button (directly above the green LED) on the transmitter (see Figure 8). This allows the transmitter to power up while its cover is off.
AIM MODE
NOTE: Resetting from a fire alarm requires power to the receiver to be interrupted for at least one second. If not provided by the fire panel, it can be accomplished by installing a switch in series with Terminal 9.
Remote Indicator Plate
The DIS2000 Remote Indicator Plate is shipped with the DS240/ DS241 as a standard accessory. Although the Remote Indicator Plate is not required, the manufacturer recommends its installation to provide a means of checking the condition of the detector from ground level.
If a DIS2000 or DIS240 Remote Indicator Plate will be used, install the Remote Indicator Connector to the receiver now (see Figure 7).
NOTE: The DIS240 remote indicator should be located no further than 100 ft (31 m) from the receiver and wired with 18 AWG (1.2 mm) or larger wire. The DIS2000 may be wired up to 500 ft (152 m) from the receiver.
