Fire Alarm

This is a two zone conventional fire alarm control panel. It has been designed and constructed around reliable and proven technology. It has controls for testing, resetting and acknowledge the system. In case of fire it gives audio alarm and visual indication for that particular zone. Hooter output of 24V DC and relay contacts also comes ON. In case of fault it gives audio alarm and visual indication for open and short for that particular zone. Battery backup is also provided. Battery charger is built in. When mains fail, the system changes over the battery. It has the following specifications:

• Mains input : 230V AC + 10%, 50Hz
• Battery : 24V SMF
• Charger (Internal) : 24V, 0.5 Amps
• Supply output : 24V, 1.0 amps

For hooter:

• Number of zones : 4 Expandable up to 32
• Devices per zone : Smoke - 20
• Heat - 20
• MCP - No limit
• Hooter circuits : 2
• Fire relay : 5Amps @ 230V AC
• Indications : System on - 1 green LED
• Fire - 2 red LEDs
• Open - 1 amber LED
• Short - 1 amber LED
• Controls : System on

Optical smoke detectors incorporate a pulsing LED located in a chamber within the housing of the detector. The chamber is designed to exclude light from any external source. At an angle to the LED is a photo-diode which normally does not register the column of light emitted by the LED. In the event of smoke from a fire entering the chamber, the light pulse from the LED will be scattered and hence registered by the photo-diode. If the photo-diode “sees” smoke on the two following pulses, the detector changes into the alarm state and the indicator LED lights up. The detector housing is identical to that of the ionization detector but has an indicator LED which is clear in quiescent state but produces red light in alarm. It has the following features:

• Wide operating voltage
• Advanced electronic technology
• Flashing LED option
• Magnetic test switch option
• Can be used on security systems
• Electrically compatible with Series 60
• Mechanically compatible with Series 60
• Proven detection performance
• Designed to meet approvals worldwide
• Range of bases available

The thermal detector forms part of the Series 300 range of conventional detectors. This range of detectors has been produced using the latest in manufacturing and design techniques, pushing out the boundaries of existing conventional detector technology. With its multitude of innovative features, the Series 300 is a detector which ‘acts conventionally, thinks intelligently’. The thermal detector incorporates an optical chamber and a thermal element, which in turn are continually monitored by an on board processor by using algorithms developed specifically for the unit. An alarm signal is only enabled in the detector once the processor is satisfied that an incipient fire has been detected. By using a combination of inputs, the incidence of nuisance alarms is reduced while at the same time, the response time to an actual fire is also improved. It has the following features:

• Low profile design
• Low current draw
• Backward compatible with Series 100
• Detector range of bases
• Wide operating voltage 8 to 30V
• Bi-color LED detector status indicator
• Automatic drift compensation
• Programmable sensitivity
• Addressable feature
• Advanced maintenance features via remote
• Hand-held test unit
• Range of detector bases available
