How do I reset my scantronic alarm?

To reset your Scantronic 9651 / 9751 alarm after an activation, enter your 4 digit code. This will show the alarm cause. Having read the alarm cause (e.g. ‘zone 3’ activated), re-enter your 4 digit code again followed by ‘X’.

Why are beam detectors not as sensitive as ion detectors?

Beam smoke detectors do however require visible smoke and therefore may not be as sensitive as ion detectors in some applications. Since the sudden and total obscuration of the light beam is not a typical smoke signature, the detector will normally see this as a fault condition, rather than an alarm.

How does a fire detection system detect a fault?

The panel detects the low voltage /high current and a fault is signalled. In order to detect an open circuit, or detector head removal, a device is connected across the end of the zone, which can be monitored. This device can take various forms dependant on the control panel. 5 0V +24V Contact Closed when detector inserted in baseResistor

What are the different types of beam detectors?

There are two basic types of beam detector: • End to End: Transmitter and receiver are mounted at either end of the protected area. • Reflective: Transmitter and receiver are mounted in the same housing, and the beam is directed at a specially designed reflector, mounted at the opposite end of the protected area.

Which is part of a smoke detector emits a beam?

The effect which occurs when smoke, which is hotter than the surrounding air, rises until equal to the temperature of the surrounding air, causing the smoke to stop rising. TRANSMITTER (PROJECTOR) The transmitter, or projector is the section of a Projected Beam Smoke Detector that emits the light beam.

Do you need technical support for scantronic intruder alarm?

Scantronic intruder alarm systems are designed to be installed by professional specialist security installers, there is no technical support available for the product for end users. We can also supply a full range of additional intruder alarm parts such as PIR’s, batteries, power supplies, sounders, diallers etc.

Why does my scantronic 9651 alarm keep beeping?

If your 9651 alarm is beeping constantly, then the most common reason for this is that you have a battery fault with your alarm system and the main alarm panel battery needs replacing. In the case of a battery fault you’ll likely see a ‘low batt’ message on your 9651 alarm keypad, along with your alarm making a beeping noise.

What does a checking bus on a scantronic alarm mean?

If your Scantronic alarm system is showing a ‘checking bus’ message, basically what this means is that the system is doing a ‘system check’. Because the chips in Scantronic alarms are fairly rudimental, the system takes quite a while (c.20 / 30 seconds) to do a check.

What does engineer reset do on scantronic 9651?

The main reason that the 9651 has engineer reset programmed is to prevent someone tampering with your alarm system, so in the case that you open your main alarm panel (for example to replace the alarm battery) then an ‘engineer reset’ message will appear on your alarm.
