Your LEXUS fire alarm panel comes with its internal robust
Power unit, changer change over circuit mains fail to batt ery & vice versa.
Card less motherboard & express board. Panel has spaced of 2No. 17AH battery,
8 to 40 flexible zones facility with the individuals Hooter lines and a common
point which gives continuous output voltage . Also has provision of extra relay
contact.
1– Micro controller based & fault monitoring system.
2– Separate LED display for individuals zones.
3– Zones wise/common hooter facility
4– Zone wise repeaters fire & fault(optioninal).
5– Tactile type switch building evacuation, lamp test zone test walk reset the system.
6– Visual indication of common fire, common fault mains, charging low battery etc.
7– In built auto charging.
8– Audio visual indication for fire/fault(zone wise).
9– Common silence switch for accept of fire/fault/ zone/ power) and respective common relay.
10–If multiple condition appear in same time press salience switch again & again till the
streaming of condition .In that condition sounder & buzzer will activate again .After
rectification of fault press reset switch.
11–System is fully detachable card by card such as power unit, mother board, switch
pad, express board etc. Thus servicing is simple, cost effective and time saving also.
This process does not need very experienced person, thus you can easily change
the defective part
Before the installation of any device it is necessary to choose the right place.
In the case of fire alarm system it is necessary to see the following points.
1) Do not install system in high radioactive, magnetic field and moisture area.
2) Where the heavy Electric cables junction and shock hazard area.
3) In restricted area enclosed area.
4) For the installations of a panel make sure the back box assemble is held
accurately against the wall, and mark the position of the four fixing holes .
Fix it by hole.
SYSTEM COMMISSIONING
Before connection field wire is must to check them by a low voltage millimeter.
It is must be satisfied hooter or other control circuit are giving right symptom.
If found dough full please check them again. Before the system commissioning
all the detection zone lines circuit must be check the resistance between each line
& negative must be check and certified to be 4.7 Ohm +- 10%.
After the line have been found satisfactory then the detection & sounder circuit
connected as per wiring with diagram. Now connected battery supply first, power
fault & system on lamps glow(wrong connection reverse Battery lamps glow).
Now connected mains 230V mains lamps & system on glow system will silent.
Please note that
NEVER USE SPEAKER WITHOUT LINE MATCHING TRANSFORMER (LMT)
