1.0 Description

1.0 Description

These instructions cover the installation of Bosch FMM­462 (Single Action) and FMM-462-D (Dual Action)
Addressable Manual Fire Alarm Box in a fire system
supervised by a Bosch Fire Alarm Control Panel
(FACP).

Install, test and maintain the FMM-462/FMM-462-D
Addressable Manual Fire Alarm Box according to these
instructions, NFPA 72, Local Codes and the Authority
Having Jurisdiction (AHJ). Failure to follow these
instructions can result in failure of the device to operate
properly. Bosch is not responsible for improperly
installed, tested or maintained devices.

Before installing the FMM-462/FMM-462-D, read
through the D9124 Operation and Installation Guide
(P/N: 39352). The FMM-462/FMM-462-D uses Bosch’s
Addressable Expansion System for interfacing with a
control panel. You should be familiar with this system
and the associated equipment prior to installing any
devices. You should also be familiar with all applicable
local and state codes, ADA requirements and the
requirements of the AHJ.

These instructions contain procedures to
follow in order to avoid personal injury and
damage to equipment.

NFPA 72 requires a complete system-wide
functional test be performed following any
modifications, repair, upgrades or
adjustments made to the system’s
components, hardware, wiring, programming
and software/firmware.

The Bosch FMM-462/FMM-462-D Addressable Manual
Fire Alarm Box is a UL Listed fire alarm initiating
device. It can be installed along with other addressable
initiating devices on a D9124 data expansion loop.

Attached to the manual fire alarm box is a factory­installed POPIT (P/N: 37519). The POPIT module is
addressed using on-board slide switches and is then
connected to a D9124 data expansion loop. The POPIT
is polled every 150 to 300 ms and reports any opens,
shorts, or ground faults on the manual fire alarm box
wiring.

The FMM-462/FMM-462-D is generally installed at
building exits such as stairways or lobbies. Persons
evacuating the building during an emergency are able to
initiate an alarm by pulling down a lever. The latching
pull-down lever on the FMM-462/FMM-462-D requires
a key to reset. This allows the origin of the alarm to be
determined easily.

The FMM-462/FMM-462-D is a high quality, die cast
device constructed entirely of nontoxic materials. It has
a low profile and rounded edges to fit most design
requirements. All components are pre-painted or have
plated surfaces to inhibit corrosion.

The FMM-462/FMM-462-D is compatible with the
following Bosch Control Panels: D7212G, D7412G,
D9412G, D7112, D7412, D8112, D9412, D7212B, and
D9112B.

The FMM-462/FMM-462-D is also compatible with the
following Bosch accessories: FMM-BB-R Deep Surface
Mount Back Box and FMM-100GR Replacement Glass
Rod.

2.0 Installation

2.1 Wiring

The FMM-462/FMM-462-D Addressable Manual Fire
Alarm Box is a single action device with a white pull­down lever in its center. The lever is easily accessible to
persons either initiating an alarm or testing the fire
alarm system. It also has a built-in break glass rod
carrier that holds a standard glass rod. Pulling down the
lever latches it in place, breaks the glass rod, and causes
a short across the POPIT sensor loop. The alarm is then
detected by the D9124 Fire Alarm Control Panel
(FACP). The pull-down lever cannot be reset until the
correct key is inserted into the lock and the unit is
opened. The lever can then be restored to its normal
position.

Use the following instructions to install the FMM-462/
FMM-462-D Manual Fire Alarm Box correctly (refer to
Figure 1 on page 3).

1) Open the POPIT Module (P/N: 37519) using a
small slotted screwdriver.

2) Set the POPIT address using the on-board slide
switches. Refer to the D9124 Operation and

Installation Guide (P/N: 39352) and the D9124
Program Record Sheet (P/N: 50098) for POPIT

addressing information.

3) Strip off approximately 1/4 in. (6.4 mm) of
insulation from each data expansion loop wire
and insert under the appropriate data terminal.

There are four screw terminals on the
circuit board. One is marked positive and
another is marked negative. The wires from
the data expansion loop connect to these
two terminals. The other two terminals are
marked sensor loop. Do not remove the
wires connecting the manual fire alarm box
to the POPIT sensor loop.

4) Tighten each screw terminal down securely. Be
careful not to strip the terminals by
overtightening.

2.3 Installing the Glass Rod

When installing the glass rod, use the following
procedure:

1) Open the FMM-462/FMM-462-D using the key
supplied with the unit. Inside, below the pull­down lever, there is a narrow slot for the rod to
sit in.

2) Insert one end of the glass rod under the spring
tab.

3) With one finger, lift the other end of the spring
tab, allowing the glass rod to slip into place.

4) When replacing a broken glass rod, remove all
debris prior to installing a new rod to ensure the
manual fire alarm box is able to close and lock
securely.

2.2 Mounting

The FMM-462/FMM-462-D mounts to a standard single
gang switch box, plaster ring or other approved
electrical box. The POPIT module and all data
expansion loop wiring should easily fit inside. Insert two
screws through the slotted screw holes and tighten down
securely.

Ensure no wires are pinched between the
mounting box and the manual fire alarm
box. A sustained short on the data
expansion loop wiring can damage the
D9124 Fire Alarm Control Panel ZONEX
modules.
