4.0 Operating Guide

For additional information on operating this system, see

the DS7400Xi (Ver. 4+) User's Guide (P/N: 43851) and

the front cover of this Reference Guide.

4.1 Emergency Procedures

4.1.1 Identifying Alarm Sounds

Your alarm system might be programmed for a steady

alarm sound or a pulsed alarm sound. It is important to

learn the difference between a fire alarm sound and an

intrusion alarm sound before you are confronted with

an actual emergency.

4.1.2 Silencing Alarms

All alarms can be silenced with any PIN that has disarm

privileges. Entering your [PIN][Off] silences the alarm

and turns off (disarm) the control panel.

4.1.3 Fire Alarms

Fire alarms are silenced using the same procedure as

intrusion alarms: a [PIN] (with disarm privileges) plus

the [Off] key.

The Fire alarm system is not reset until alarms at smoke

detectors are cleared by using the [System Reset]

command. The Fire alarm system is not functional until

this procedure has been followed. See Section 4.2 Fire

Reset/Fire Trouble.

4.2 Fire Reset/Fire Trouble

4.2.1 Fire Reset

During a fire alarm, exit the premises immediately.

When you have determined there is no fire, you can

silence the bells/sirens before you initiate the [System

Reset] command: [PIN][System Reset].

Before the [System Reset] command is used, determine

which smoke detector has alarmed so the monitoring

company can verify its operation.

To use the System Reset command

sequence, your PIN must have disarm

privileges. The System Reset command

performs a fire reset, a battery test, and

clears all system troubles.

If the System Reset command is not

performed after 24 hours of the fire alarm,

the keypad sounds and it displays "Fire

Alarm Not Reset." If the sounders are

silenced and the system is reset properly,

this warning does not occur.

4.2.2 Fire Trouble

A Fire Trouble message with a zone number signifies a

problem with the fire system, such as a break in the

wiring that monitors smoke detectors. If the unit is in

the commercial fire mode, a Fire Trouble message

with no zone number indicates a ground fault.

A Fire Trouble is indicated by a short beep from the

keypad sounders every 10 seconds. The DS7447E/

DS7447V2 displays “Fire Trouble” followed by the

zones in a trouble condition. The DS7445i/DS7445V2

turns the Fire and Trouble Lights on steady and lights

the corresponding zone LEDs.

Notify your installing company immediately if the Fire

Trouble message is displayed.

The Fire Trouble beep can be silenced with any [PIN]

plus the [Off] key. After problems are remedied, a

[PIN] plus the [Off] key should again be entered to

clear the “Fire Trouble” display.

4.2.3 Dirty Smoke

A Dirty Smoke display, followed by a zone number

and accompanied by a beep every ten seconds

indicates that the smoke detector for that zone requires

cleaning or replacement. The smoke detector also

gives a Dirty indication by flashing its LED once per

second. The Dirty Smoke beep can be silenced by any

[PIN] plus the [Off] key.

Notify your installing company immediately if the

Dirty Smoke message is displayed.
