4. Wiring
The terminals are shown in fig. 3 and on the wiring
diagram glued to the inside of the cover.
4.1 E-Bus (fi g. 6)
Cable type 24 AWG 7 x Ø 0,2 mm is recommended.
The to tal length of the E-Bus cable must not exceed
500 m. The E-Bus must be connected to the cen tral
control unit (B1-, B2, B3, B4+). It may be routed in
parallel to other accessories. If shielded cable is used,
all the shields must be connected at one point, e.g. at
an NC terminal.
4.2 Tamper contact
If the SMT 12 circuit board is not fitted in the SAT
12 housing, the plug connector (fig. 3
W
) must be
connected to an external tamper contact or be short-
circuited. Use the socket connector provided to connect
to an external tamper con tact.
4.3 Inputs (fi g. 7)
All inputs can be operated in modes 1 to 4 and 6 to
7 (fig. 7). Inputs Z1 to Z2 can also be operated with
glass break alarms. To do this, the relevant switches
SW1 to SW2 must be closed and one terminal of each
glass break sensor connected to one of outputs O1 to
O2, which must be programmed for «Latching sensor
reset». When wiring fire detectors, any trou ble out put
present can be looped directly into the line. For fire
detectors where the power has to be disconnected
to reset the alarm, the negative can be connected
via an output which is programmed as a «Latching
sensor reset» output.
The emergency exit has to be wired like mode 6. A
short circuit of the input will reset the corresponding
output.
5. Close and seal the housing
1 - Engage the cover in the retainer at the top (fig. 1).
2 - Close the cover and tighten the retaining screw
(fig. 1).
3 - Use eye (fig. 2
R
) for sealing.
