VA and VZ inputs in standby mode (the valve enabled
–disabled) are connected with
CA and CZ outputs, which makes it possible, among other things, to carry out the damper
ventilation function without any interruption. Option with venting:
CA and CZ outputs in standby mode are vented by means of an integrated drain
(vent) valves. After pressurising the VA or VZ input (from the alarm or ventilation box), a
connection between the VA input and CA output or between VZ input and CZ output is set
up.
Installation:
1. Make the following connections:
CA
– OPEN side of the actuator / VA – OPEN ventilation or smoke extraction
circuit
CZ
– CLOSED side of the actuator / VZ – CLOSED ventilation or smoke extraction
circuit
2. TAVE 3 should be mounted so that it is placed in the fire gas stream, and the
socket for the cylinder screwing is located at the top.
3. Seal the threaded connections with Teflon tape or Loctite 243 liquid sealing, which
should only be applied on the outer thread of the connector.
4. Use only cylinders provided by Smay Sp. z o.o., because this determines the
validity of the Certificate.
Setting and operation:
1. Unscrew the pin tensioning bolt home.
2. Install the ampoule so that the sharp end of the ampoule is pointed towards the
nut in the ampoule fixture.
3. Tighten the nut home until resistance is felt, then additionally tighten the nut half a
turn, pressing the ampoule.
4. Tighten the pin tensioning bolt home.
5. Examine visually if the pin is placed below the thread level in the hole for the CO
2
cylinder.
6. Slightly lubricate the gasket (o-ring) in the hole for the CO
2
cylinder.
7. Screw the CO
2
cylinder in.
8. After launching/triggering remove the empty CO
2
cylinder (attention: there may still
be high pressure in the valve) and repeat the operations in order to set the thermal
trip again.
After emergency triggering reset the valve manually.
