1. Introduction

The Alarm System

The 9751 alarm system comprises a control unit, one or more keypads, and

various detectors.

The control unit is a box that houses the main controller, power supply,

stand-by battery, and any remote communicator. The control unit is normally

fitted out of sight in a safe place (for example under the stairs).

The detectors are installed at various places, or zones, around the premises.

If something triggers a detector then the detector signals back to the control

unit. How the control unit reacts depends on whether the system is set or

unset.

When set the control unit raises an alarm whenever a detector is triggered.

The alarm might be a bell or strobe on the outside of your premises, or it

might be a silent signal from the communicator over the telephone line to an

Alarm Receiving Centre (ARC). When unset the system does not raise an

alarm if a detector is triggered.

The system provides different setting Levels, labelled A, B, and C. Level A

sets the whole system, protecting all of the premises covered by the alarm

system. Levels B and C set part of the system, protecting part of the

premises while the rest is in use. The system raises an alarm when a detec-

tor belonging to a set Level is triggered. The Installer allocates zones to

Levels B and C during installation. Ask your Installer to tell you which zone is

allocated to each Level.

Your premises may be fitted with 24 hour zones and panic alarm zones. If

these zones are triggered the system will raise an alarm whether or not any

Level is set.

The Keypad

Your alarm system is fitted with one or more 9930 liquid crystal display (LCD)

keypads. You can set and unset the system from the keypad, read the event

log and make minor changes to the way the system operates.

You must enter an access code before the system will accept commands

from the keypad. The system can store up to 16 different access codes,

providing secure access for 16 users.

Figure 1 on the next page shows the keypad in detail.
