terminals, and supports up to 500mA, and 80VDC.
The detection circuit is connected in Zn+ and Zn- terminals. This circuit must always be
terminated by a resistor of 3300Ω, 1/4W.
In each zone can be connected up to 32 detectors and any number of callpoints. When
mounting callpoints, it should be used a zener diode, in series, of 5V1, 1/4W.
Figure 3 shows a circuit only with detectors. The termination resistor (R: 3300Ω, 1/4W)
should be connected at the end-of-line, in parallel with the detectors.
A zone can also have only callpoints in its circuit.
Figure 4 shows how to make the connections between callpoints, zener
diodes (Z: 5V1, 1/4W) and termination resistor (R: 3300Ω, 1/4W). In such case,
delays will be ignored and the alarm is immediately activated.
In the example shown in Figure 5, it is possible to see how to connect
detectors and callpoints in the same zone. Such zone, when configured as
'intelligent', will distinguish if an actuation comes from a detector or from a
callpoint. If delay mode is activated, the delay will only be applied to detectors.
Auxiliary outputs that are available for each zone can be used as switches
that close a connection when actuated. Figure 6 represents a circuit with a
lamp (L), using an external power-supply (P). (Maximum specifications: 80
VDC, 500mA).
4.3 Relays:
For each relay there are 3 terminals, as shown in Figure 7. Terminal C is the common. Terminals NC
and NO are, respectively, normally-closed and normally-opened.
The relays in the FIREWALL are capable of controlling voltages up to 250VAC and currents up to 10A.
The cables to use with these circuits should be in accordance with the current to use. As an example, for
10A@250VAC it should be used a cable similar to the one of main power supply (A05VV-F with 3 wires of
section of 1,5 mm
2
).
Note
: Relays are programmable so they can be used to signal alarms and/or fails. When programmed to signal
at least a fail, a relay will have a complementary behavior, i.e., in standby, the internal coil of the relay remains
activated, and, in case of fail, it is deactivated.
4.4 Sounders:
This output allows to control one or more sounders in parallel (maximum specifications 500mA @ 24VDC).
It is protected by a fuse and it is monitored for detection of fails due to short-circuit or open-circuit.
It should be used a termination resistor of 3300Ω, 1/4W, at the end-of-line and in parallel with the sounder(s).
4.5 Auxiliary power:
It is available an auxiliary output to power external equipments up to: 500mA @ 24VDC.
4.6 Battery:
It is mandatory to use a battery (lead-acid), not included with the equipment, of 12VDC, 7Ah; or two batteries of 6VDC,
12Ah (connected in series) that allows a greater autonomy in the event of main-power shutdown.
Note
: Pay attention to the polarity. When using 2 batteries, the voltage of each one must be 6VDC and not
12VDC. Do not use other type of batteries to avoid explosion!
4.7 Maintenance:
To ensure the correct operation of the control panel, periodically test the functions of all systems.
With a minimum periodicity of 6 months, verify if the battery level is above 12VDC (with 1 battery) or 6VDC (with 2 batteries).
When exchanging fuses use only the same reference.
Note
: Before any maintenance take place, the control panel should be turned off.
5 - Testing the system:
Once all connections are made, the entire system should be tested.
When powered on, the control panel should not be signaling any fault (unused zones must be deactivated).
Disconnect the battery and check if the battery fault is signaled. Connect it again and then check if the control panel returns to its initial state.
Break a zone circuit (removing a detector) and verify that the open-circuit condition is detected. Establish a short circuit between the terminals of
the zone and verify that the fault is signaled. Repeat for all zones in use.
Follow similar procedures for the circuit of the Sounder (remove the sounder and establish a short circuit). Verify that the sounder is off.
Using appropriate mechanisms to simulate a fire situation by activating a detector. Check that the control panel signals the alarm, activating the
sounder (may have a delay if the delay mode is active). Since version FW 3.20, the FIREWALL has an autotest mode, which resets the system when
an alarm occurs, see 7.6.
Also check if the relay(s) switch properly according to your programming.
