MODEL E 31G
This fire, intruder & temperature alarm system is specially 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 and unsafe room temperature.
E 31G comprises three independent sections which continuously monitor the protected premises and on generation of any alarm i.e. fire, door & temperature alarm, this system offers audiovisual local alarms as well as potential free relay contacts for remote alarm.
FEATURES
System basic features
[a] Fire alarm
[b] Intruder alarm
[c] Temperature high alarm
[a] Fire alarm: The control panel generates audiovisual alarm on receipt of trigger commands from fire sensor. Beeper 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 LM 35 sensor is used, which is placed on main board inside the panel that senses the room temperature and if it is exceeds the safe limit, system triggers the visual and remote alarms.
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.
Optional feature: Fire II and Fire sensor Fail alarm
The control panel generates Fire II alarm as an optional alarm. Fire sensor and its connecting cable has a vital role in the circuit therefore those are continuously monitored electrically, if either of them get short or open by any means, the circuit triggers remote alarm, fault tone and glows corresponding indicator on front panel.
