Fire-lite alarms Honeywell mmf-302-6 User manual

BEFORE INSTALLING

This information is included as a quick reference installation guide. Refer to

the appropriate Fire•Lite control panel installation manual for detailed sys-

tem information. If the modules will be installed in an existing operational

system, inform the operator and local authority that the system will be tempo-

rarily out of service. Disconnect the power to the control panel before install-

ing the modules. This system contains static sensitive components. Always

ground yourself with a proper wrist strap before handling any circuits so that

static charges are removed from the body. The module housing should also

be grounded.

GENERAL DESCRIPTION

The MMF-302-6 Six Zone Interface Module is intended for use in an intelli-

gent alarm system. Each module provides an interface between the intelligent

alarm system and a conventional alarm system loop. A common SLC input is

used for all modules, and the initiating device loops share a common super-

visory supply and ground. Otherwise, each monitor operates independently

from the others. Each module has its own unique address.

A pair of rotary code switches is used to set the address of the first module

from 01 to 154. The remaining modules are automatically assigned to the next

five higher addresses. Provisions are included for disabling a maximum of two

unused modules to release the addresses to be used elsewhere. Each mod-

ule also has panel controlled bicolor LED indicators. The panel can cause the

LEDs to blink, latch on, or latch off.

A list of compatible two-wire System Sensor Smoke detectors for use with the

MMF-302-6 is available on the System Sensor website at systemsensor.com.

MMF-302-6 Six Zone Interface Module

COMPONENTS

Following are descriptions of the MMF-302-6 mounting frameworks. There are

two mounting options for MMF-302-6 modules:

• Up to six MMF-302-6 modules can be installed on a CH-6 in a BB-6F

cabinet

• One or two MMF-302-6 modules can be installed in a BB-2F cabinet

Chassis

The CH-6 chassis is used to mount MMF-302-6 modules in a BB-6F cabinet.

It accommodates up to six MMF-302-6 modules in a single cabinet row three

modules wide and two modules deep.

INSTALLATION STEPS

1. Cabinet Mounting

In a clean, dry area, mount the backbox using the four holes provided in the

back surface of the cabinet (Figure 3).

2. Chassis Installation

The CH-6 chassis is mounted in the BB-6F cabinet. It is attached to the two

PEM studs on the back wall of the cabinet with two 8-32 hex nuts. The hex

nuts are included with the chassis (Figure 4).

C0239-00

The BB-2F cabinet comes with the chassis already installed, so no mounting

is necessary.

3. Module Installation

There are two methods for installing a module in the rear position of a chas-

sis. Method one is for installation of a rear module only, when no module will

be installed in front of it. Refer to Figure 5 for instructions. Method two is for

installation of a rear module when another module will be installed in the

chassis position in front of it. Refer to Figures 6a and 6b for method two. All

necessary screws and standoffs are supplied with the modules.

FIGURE 5. INSTALLATION OF REAR MODULE ONLY, METHOD ONE

C0237-00

Step 1: Insert the bottom of the MMF-302-6 module down into a

rear slot on the chassis.

Step 2: Carefully swing the upper edge of the board back towards the back of

the chassis until it touches the two standoffs.

Step 3: Align two 4-40 screws with the two standoffs and tighten.

Step 4: Address and wire the modules according to the instructions in this

manual.

The steps in Figures 6a and 6b describe and illustrate module installation

when the rear chassis position and the position in front of it will be filled.

Front position installation is possible only if the rear position is filled with

another module.

CHASSIS POSITION, METHOD TWO

C0225-00

Step 1: Insert the bottom edge of the MMF-302-6 module down into a rear

slot of the chassis.

Step 2: Carefully swing the upper edge of the board towards the back of the

chassis until it touches the short standoff attached to the chassis.

Step 3: Align the long standoff with the short standoff and tighten.

FIGURE 6B. INSTALLATION OF MMF-302-6 MODULE IN FRONT CHASSIS

POSITION

C0226-00

Step 1: Insert the bottom edge of the MMF-302-6 module down into a front

slot of the chassis.

Step 2: Carefully swing the upper edge of the board towards the back of the

chassis until it touches the 1.25˝ (32 mm) standoffs installed on the

rear module.

Step 3: Align two 4-40 screws with the two standoffs and tighten.

Step 4: Address and wire the modules according to the instructions in this

manual.

WIRING

NOTE: All wiring must conform to applicable local codes, ordinances, and

regulations.

1. Install module wiring in accordance with the job drawings and appropri-

ate wiring diagrams.

2. All wiring to the MMF-302-6 is done via terminal blocks. In order to

properly make electrical connections strip approximately 0.25˝ of insu-

lation from the end of wire, sliding the bare end of the wire under the

clamping plate screw.

3. Set the address on the modules per the job drawing. Use the rotary code

switches to set the address of the first module (between 01 and 154).

In Class B operation, the remaining modules are automatically assigned to the

next five higher addresses. For example, if the base address switch is set to 28,

the next five modules will be addressed to 29, 30, 31, 32 and 33.

The module is shipped in Class B position, remove shunts for Class A. When

operating in Class A, alternate modules are paired together (+0/+1, +2/+3,

+4/+5), resulting in a total of three modules. For example, if the base ad-

dress switch is set to 28, then 30 and 32 will be automatically assigned to the

modules while 29, 31 and 33 are available to be used for other modules on the

SLC. For Class A and B operation, DO NOT set the lowest address above 154,

as the other modules will be assigned to nonexistent addresses.

NOTE: Some panels support extended addressing. In order to set the module

above address 99 on compatible systems, carefully remove the stop on the

upper rotary switch (see Figure 7). If the panel does not support extended ad-

dressing, do not set the lowest address above 94.

WIRING NOTES

• Power-limited circuits must employ type FPL, FPLR, or FPLP cable as

required by Article 760 of the NEC.

• All wiring must be in accordance with the NEC, NFPA 72 and all other

applicable codes and standards. All external power supplies must be

power limited with battery back-up. All external power supplies and

detectors must be UL listed for fire protection signaling applications.

PROGRAMMING

Connect the module to listed-compatible control panels only. Refer to panel

installation documentation to confirm compatibility.

The modules are programmed as devices in each system according to the pro-

gramming instructions in the appropriate FACP manual.

3 I56-1900-023

4. A shunt is provided to disable a maximum of

two unused modules in Class B operation and

Class A operation. Modules are disabled from

the highest address and work downward. If

two modules are disabled, the lowest four ad-

dresses will be functional, while the highest

two will be disabled. For example, in Class B

operation, if the shunt for Address Disable is

placed on “two” and the base switch is set to 28,

the modules will be assigned to 28, 29, 30 and 31 while disabling the

highest two positions.

NOTE: Place unused shunts on single pin to store on board for future use.

NOTE: Power must not be applied to the unit when changing functionality of

the shunts.
