This fire alarm and security system is exclusively designed to meet the safety requirements and to protect the unmanned equipment rooms, microwave stations, exchanges etc. from unpredictable events such as fire, unauthorized intrusion, robbery etc. EX 324 comprises four independent sections which continuously monitor the protected premises and on generation of any alarm i.e. fire, door, temp high & mains fail alarm. This system offers four independent potential free contacts for extension of remote alarm for four separate operator.
System basic features
[a] Fire alarm
[b] Intruder alarm
[c] Temperature alarm
[d] Mains Fail alarm
[a] Fire alarm: The control panel generates audiovisual alarm on receipt of trigger commands from fire sensor. Special tones are used to indicate the fire condition. This will alert the local staff so as to activate the firefighting device or to take other appropriate measures.
[b] Intruder alarm: Unmanned equipment rooms such as microwave stations or exchanges are monitored and protected from unauthorized entry. For this purpose magnetic door sensors are used to trigger the control circuit that generates the audiovisual alarm.
[c] Temperature alarm: The room temperature is continuously monitored by control panel. For this purpose RTD sensor is used, that senses the room temperature and if it is exceeds the safe limit, system Triggers the visual and remote alarms.
[d] Mains fail alarm: System provides alarm for mains fail. Normally Closed (NC) type contact.
All above sections continuously monitor the protected premises and generates respective alarms and also provide the trigger signal for remote alarms through potential free relay contacts. Those individual alarms can be further sent to the central control station or switch room.
