1. Introduction

rechargeable battery which will continue to ring the bell/siren if the wiring is

cut or the casing is tampered with. This type of module is used to power a

sounder or bell which will typically draw no more than 450mA. Opening the

bell tamper switch or damaging the wiring will cause a Full Alarm to occur.

The trigger provided by the panel is negative applied in alarm condition

(SAB).

The control panel uses an internal loudspeaker to give Entry, Exit and

Alarm tones. There is a volume adjuster within the panel which allows you to

change the volume of the Entry/Exit tones. An external 16 ohm loudspeaker

(for example a Type 9040) can also be connected to the panel.

The Installer can program the panel to sound the alarm for one of several set

times and then fall silent.

Re-Arm

The Installer can program the control panel to rearm itself after an alarm.

With this option selected, the panel silences the alarm at the end of its

programmed time and rearms ready for another activation. If the option is not

selected, the internal and external sounders will remain silent until the user

enters their access code. The panel can be programmed to rearm up to three

times, or always.

First to Alarm Indication and Shock Sensor Reset

The panel provides a Programmable Output (O/P) which can be used for

PIR Set Latch or Shock Sensor Reset.

If two or more PIR detectors are fitted to a zone then the panel cannot

identify which unit caused an alarm. Connecting O/P to the Latch input of the

detectors on the zone overcomes this problem. When O/P is programmed as

PIR Set Latch the panel activates the output when the exit time expires,

resetting the detectors. When an alarm occurs the panel deactivates the

output. This latches the indicator of the unit triggered and inhibits all other

units. The first detector to alarm will then have its activity LED glowing, while

the others will be dark. This output can also be used for break glass detec-

tors. (Note that the panel also deactivates the output when the system is

unset.)

Stand-alone shock sensors normally latch when they are triggered. To reset

the detectors automatically, connect the negative supply from the detectors

to O/P and program O/P as Shock Sensor Reset. At the start of the exit time

the panel deactivates the output for six seconds to clear the latched devices.

(Refer to the sensor manufacturer's instructions for more details on the reset

methods available.)

Communicator Outputs

The panel provides two output pins which can be used to trigger a Speech or

Digital Communicator. One pin is fixed as PA and the other as Intruder. The
