WARNING
TO PREVENT DETECTOR CONTAMINATION AND SUBSEQUENT
WARRANTY CANCELLATION, THE SMOKE DETECTOR MUST
REMAIN COVERED UNTIL THE AREA IS CLEAN AND DUST FREE.
INSTALLING THE BASE
1)
To in sure proper in stal la tion of the de tec tor head to the base, all the
wires should be prop erly ad dressed at in stal la tion:
(A) Po si tion all the wires flat against ter mi nals.
(B) Fas ten the wires away from con nec tor ter mi nals.
2)
If you use a jumper wire to con nect the poles of ter mi nals 2 and 5 when
test ing the de tec tor loop con ti nu ity, be sure to re move the jumper wire
prior to the in stal la tion of the de tec tor head.
3)
The end-of-line de vice shown in Fig. 1.A and Fig. 1.B should be com pat i -
ble with the con trol and in di cat ing equipment. The end-of-line su per vi -
sory re lay used should be rated for the DC power volt age used.
4)
Open area smoke de tec tors are in tended for mount ing on a ceil ing or a
wall in ac cor dance with the fire stan dard in your coun try.
5)
The base of the smoke de tec tor can be mounted di rectly onto an elec tri cal junc -
tion box such as an oc tag o nal (75 mm, 90 mm or 100 mm), a round (75 mm), or
a square (100 mm) box with out us ing any type of me chan i cal adapter.
INSTALLING THE HEAD
1)
Align the com po nents as shown in Fig. 2.
2)
Mate the de tec tor head onto the base and twist clock wise to se cure it.
3)
Do not in stall the de tec tor head un til the area is thor oughly cleaned of
con struc tion de bris, dusts, etc. The max i mum num ber of smoke de tec -
tor in stalled in the same cir cuit is 30 units.
ADJUSTING THE RELAY FOR NO/NC
The nor mal con di tion for the re lay is "nor mally open" (NO).
1)
To ad just the nor mal con di tion of the re lay to "nor mally closed" (NC), in -
sert a screw driver into the rect an gu lar hole lo cated on the side be tween
the front cover and base and ro tate to re move the front cover.
2)
Re fer to Fig. 3. There is a jumper head next to the re lay on the PCB. Re -
move the jumper head and re in sert it in the NC po si tion.
3)
Care fully re place the front cover.
Re lay con tact rat ing:
1 A @ 30 VDC, 0.5 A @ 125 VAC.
