Wiring & Powering The System; Grounding The System - ADEMCO via30 Installation Instructions Manual

(See Summary of ConnectIons Diagram on Page 47)
IMPORTANT:
Grounding the System
Terminals and
Connections
Do not connect the battery, or plug In the AC transformer,
until all other wiring connections have been completed.
Terminal 21 is the earth ground connection point. In order for the protective
devices in this product to be effective, the designated terminal must be
terminated in a good earth ground. The following are examples of good eatth
grounds available at most installations:
Metal cold water pipe: Use a non-corrosive metal strap firmly secured to the
pipe to which the lead is electrically connected and secured.
AC power outlet ground: Available from 3-prong, 120 VAC power outlets
only. To test the integrity of the ground terminal, use a 3-wire circuit tester with
neon lamp indicators, such as the UL Listed Ideal Model 61-035, or equivalent,
available at most electrical supply stores.
1 & 2: AC Input (16.5VAC, 25VA) from No. 1321/TF2 plug-in transformer
(in U.S.A.).
Note: For Canadian installations, a No. 1321CN transformer must be
used.
3:
Alarm relay output(+), 12VDC, 2.OA maximum
(600mA max Alarm plus Aux Power for UL usage).
4: Alarm Output/Auxiliary Power/Wired Fire/Console(s)/ Optional 4281,5881,
4219, 4229, or 4204 (BLACK lead). Ground (-) Returnt.
5:
Auxiliary/Wired Fire/Console(s)/Optional 4281, 5881, 4219, 4229, or 4204
(RED lead) Power:
+12VDC at 500mA max ~.
6: Data In from Console(s) /Optional 4281, 5881, 4219, 4229, or 4204
(GREEN)t.
7: Data Out to Console(s)/Optional 4281, 5881, 4219, 4229, or 4204
(YELLOW)t.
8–1 3: not used
14: Zone 5. (When Zones 5 and/or 6 are used, a
wired between the farthest sensor connected
low side of the zone.)
15: Zones 5 and 6 Return.
16: Zone6
17: Handset (TIP).
18: Handset (RING).
19:
Incoming Phone Line (TIP).
20:
Incoming Phone Line (RING).
1,000
Ohm EOLR should be
to the zone terminal and the
21: EARTH GROUND (a proper earth ground must be provided to protect the
system from lightning and electrostatic discharge damage).
Warning: To prevent the risk of electrical shock, disconnect the telephone line
at the Te/cojack before servicing the unit.
RED LEAD: Battery (+). When AC is present, 13.8VDC is being developed to
recharge a gel lead acid battery and when AC is absent, 12VDC current is
drawn from the battery. Battery lead reversal will blow the battery fuse.
BLACK LEAD: Battery (-).
t
Up to 4 consoles may be used (check total auxiliary current, per SPEC/F/-
CAVONS). Consoles need not necessarily be on individual home runs, but
no more than 220 of #22 wire or 550' of #18 wire should be used for each
run.
Addressable consoles (e.g., 4137AD and 5137AD) may be used, if they
are set to their non-addressable mode (device ID 31...all DIP switch posi-
tions UP).
