DIP Switch Settings

4.0 DIP Switch Settings

Each annunciator needs to be assigned a unique, sequential address via DIP switches SW1-

1, SW1-2, and SW1-3. DIP switch SW1-4 is used to allow disabling of some front panel slide

switches.

Set the annunciator address (see the manual for the fire alarm control panel being used), as

follows in the table below

4.1 Jumper Selection

Jumper JP1 connects pins 1 and 2 and thus provides an eight bit checksum. The eight bit

checksum is used for the MR-2300 Series Panel.

JW4 (Orange Wire)

Jumper Intact = Buzzer silence & Lamp Test local function only. System Reset & Signal

Silence are disabled.

Cut Jumper (Orange Wire) to have all remote functions operate.

SW1-1 = Address A0

Three digit address of the annunciator (address

range 1 to 7 inclusive)

SW1-2 = Address A1

SW1-3 = Address A2

SW1-4 =

When SW1-4 is “off”, the System Reset and Signal Silence slide-switches are

always disabled, regardless of the operation of the keyswitch. The Buzzer

Silence and Lamp Test slide-switches will operate with the use of the

keyswitch.

When SW1-4 is “on”, all four slide -switches on the front panel will operate

with the use of the keyswitch.
