• Transmitter Terminals 1 & 2:
Input power terminals. See Section 2.0 Specifications on page 1
for the operating voltages of the DS240 and DS241.
• Receiver Terminals 1, 2 & 3:
Form "C" Auxiliary relay contacts. Terminals 1 & 2 will open on fire
alarm; Terminals 2 & 3 will close (short) on fire alarm.
• Receiver Terminals 4 & 5:
Normally Open Fire alarm contacts will close (short) on fire
alarm.
• Receiver Terminals 6 & 7:
Normally Closed Trouble contacts will open for trouble alarm.
• Receiver Terminals 8 & 9:
Input power terminals. See Section 2.0 Specifications on page 1
for the operating voltages of the DS240 and DS241.
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.
