Section One: LED-10 Series Annunciators

LED-10

The Fire•Lite LED-10 Series Annunciators consist of the LED-10, LED-10L and LED­10LS2. They are compact, attractive LED-type fire annunciators designed for use with
the MS-5210UD Fire Alarm Control Communicator. The LED-10L and LED-10LS2 are
models which do not have function switches or a key-switch. The LED-10LS2 is
intended primarily for Canadian installations since it provides zone 9 and 10 alarm LEDs
that are yellow for supervisory functions.

The LED-10 Series Annunciators are capable of displaying independent zone
process monitor alarm, trouble and supervisory status. They also provide system
status LEDs to display Power, Alarm, Trouble, Supervisory and Signals Silenced
conditions. The LED-10 model is also capable of performing system acknowledge,
silence, drill and reset remotely.

Communication between the control panel and the LED-10 Series Annunciators is
accomplished over a two-wire serial interface employing the EIA-485 communication
standard. Up to 32 LED-10 Series Annunciators may be connected to the two-wire EIA­485 circuit. The annunciators may be powered from the host FACP or remote, UL
listed, filtered, regulated power supplies.

Piezo Sounder

The LED-10 Series sounder, if enabled, will be activated
when any new alarm or trouble is received from the
panel. It is silenced by pressing an ACKNOWLEDGE or
SILENCE switch. Piezo must not be disabled without
approval of LAHJ (Local Authority Having Jurisdiction).

SW1 DIP Switch Settings

The OPEN position on SW1 is the OFF state. Refer to Figure 1-3 for an explanation of
DIP switch positions. SW1 switch settings are as follows:

1 through 6 - LED-10 Series annunciator address switches.

The first six switches are used to set the address of the annunciator. The OFF
(OPEN) up position equals a binary 1 and the ON down position equals a
binary 0. Refer to Table 1-1 for information on setting these switches for
specific addresses. Each LED-10 Series annunciator connected to the EIA­485 communication bus must have a unique address.

7 - Not used
8 - ON = Receive/Transmit, OFF (OPEN) = Receive Only

Switch 8 set to ON position enables Receive/Transmit mode for the LED-10
Series annunciator. This allows the annunciator to receive and display system
status information and to transmit supervision status. It also allows the LED-10
model to transmit system control data such as Acknowledge/Step, Reset,
Signal Silence and Drill. Switch 8 set to the OFF position enables Receive
Only mode which allows the annunciator to receive and display system status
information but prevents supervision status from being transmitted back to the
FACP. It also prevents function switch operation on the LED-10 model. To
ensure annunciator supervision for all LED-10 Series annunciators and
function switch capability for the LED-10 model, each annunciator connected to
the EIA-485 communication bus must have a unique address and should be
set to enable Receive/Transmit Mode.

DOWN POSITION = ON

NOTE - SW1 DIP switch settings as illustrated in Figure 1-3 are as follows:

1) DIP switches 1 - 6: Address 08 (see Table 1-1).

2) DIP switch 7: Not used.

3) DIP switch 8: ON = Receive/Transmit

UP (OPEN) POSITION = OFF

Figure 1-3: SW1 DIP Switch Settings Example

Document 50400 Rev B 10/27/97 P/N 50400:B

SW2 DIP Switch Settings

SW2 switch settings are as follows:

1 - LED-10 Only (not used on LED-10L and LED-10LS2)
ON = Key-switch Enable, OFF = Key-switch Disable.

Switch 1 set to the ON position enables the key-switch operation. The key­switch may now be used to enable LED-10 model membrane (control) switches,
allowing remote switch functions, or lockout the switches, preventing remote
switch functions. Switch 1 set to the OFF position disables the key-switch
operation. Refer to Operation Section for key-switch function description.

2 - ON = Piezo sounder enabled, OFF = Piezo sounder disabled.

CAUTION: Piezo sounder must not be disabled without prior approval of the
Local Authority Having Jurisdiction.

UP POSITION = OFF

DOWN POSITION = ON

Figure 1-4: SW2 DIP Switch Settings Example

LED-10 Series Addressing

SW1 DIP switches 1 through 6 are used for addressing the LED-10 Series annuncia­tors.

Each device connected to the EIA-485 communication bus must have a unique

address.

and for individual supervision of each annunciator by the FACP. Switch settings and
the corresponding addresses are shown in Table 1-1. (Address '00' is invalid).

Note: 1 = Switch in the UP (OPEN) position.

8

This allows specific data to be transmitted between the FACP and that device

0 = Switch in the DOWN position.

Table 1-1: LED-10 Series Annunciator Addressing

Typical Configuration

The LED-10 Series annunciators indicate the status of the MS-5210UD, display zone
status and require no programming. In addition, the LED-10 model offers multiple
annunciator locations with the capability of remote Acknowledge, Signal Silence, Drill
and Reset functions.

NOTES:

1) EIA-485: Maximum of 6,000 feet (1,800 m) total cable length from FACP to LED-10 Series
annunciators. Circuit is power-limited.

2) Up to 32 LED-10 Series annunciators may be used on the EIA-485 circuit. The MS-5210UD
can power a maximum of seven annunciators. If additional annunciators are connected, the
Fire•Lite FCPS-24F may be used to supply additional power. (Power supplies used for this
purpose must have their negative terminals commoned together).

3) Between each annunciator are four wires: A twisted-shielded pair for data communications and
a pair for 24 VDC power.

4) A mix of LED-10 Series annunciators can be connected to the same EIA-485 circuit.
