D .
The primary winding of the transformer is already connected to
the terminal block, as shown in Fig. 3.3. Connect the
transformer's 16 VAC winding (the 2 free wires) across the
control module's 16 VAC terminals.
E .
Connect AC mains input – Phase
(~),
Neutral
(0)
and Ground
(
) to terminal block (see Fig. 3.3). Make sure your
installation complies with the following safety requirements list:
•
Conductors carrying the AC mains voltage should be
physically separated from other conductors used to wire
the alarm system.
•
The cross section of the mains input conductors must be
not less than 1.0 mm
2
(17 AWG).
•
The diameter of the plastic conduit for the mains cable
should be at least 16 mm (5/8 in.)
•
Insert the plastic conduit as far as 3 cm (1-1/8 in.) into the
metal case, to protect the mains conductors from the sharp
edges of the entry hole.
•
All 3 AC power supply leads must be tied together firmly
with a plastic tie wrap close as close as possible to the
terminal block to which these leads are connected.
•
The phase (~) input wire must be routed via a single-pole, 3A
exclusively dedicated circuit breaker.

Two optional kits are offered for enhancing the alarm control system:
LK-1: key-operated lock for the front lid of the metal cabinet (see A
below)
TK-1: tamper switch kit (see B below)
A . Assembling the Front Lid Lock Kit (LK-1)
The LK-1 lock kit includes the lock itself and mounting hardware as
shown in Fig. 3.4. To assemble the lock, proceed as follows:
( 1 ) Align the lock with the pre-punched hole in the lid, insert it into
the hole and use the nut to fasten it to the front lid. Tighten the
nut with a spanner wrench.
( 2 ) Mount the rotation limiter over the rotating part of the lock,
making sure that the small cam on the lock body is positioned
between the two teeth that limit the rotation angle.
( 3 ) Mount the lock bar over the rotation limiter.
( 4 ) Use spacer and the screw to tighten the entire lock assembly.
( 5 ) Insert the key into the lock and check whether the rotation
limiter allows the lock to be rotated in the desired direction.
B. Assembling the Tamper Switch Kit (TK-1)
The TK-1 kit includes the tamper switch with two wires soldered to
its terminals and two sheet metal screws. To mount the switch on
the tamper bracket, proceed as follows:
(1) Align the tamper switch with the bracket as shown in Fig. 3.5.
