3.2.3.4 Zone Humidity Sensor (ZHS) (Optional)

The Zone Humidity Sensor (ZHS) is supplied as part of the TCS22 package (Optional). The Zone Humidity Sensor (ZHS) is a bulk polymer type device. If so equipped, the sensor is premounted to the front door of the TCS22. No wiring is required.

3.2.4 WIRING – INPUTS & OUTPUTS

A shielded cable with 20 gauge copper conductors, such as National Wire & Cable Corporation NQP series cable or equivalent, is recommended for connection to the inputs and outputs of the TCS22 for distances up to 45 feet. See Table 1 for distances more than 45 feet.

3.2.4.1 Shelter Alarm Output

The Shelter Alarm Output (SA) is a

normally open set of contacts that closes whenever an alarm condition exists as sensed by the TCS22 controller. See the alarm section of this manual for an explanation of the various conditions that will send a shelter alarm.

The Form "A" contacts are SPST N.O. rated at 24 VAC, 5 A Resistive, or 24 VAC, 2 A Inductive. These rating should not be exceeded under any conditions.

These contacts may be used to trigger an alarm in the shelter or a remote alarm.

3.2.4.2 Power Transfer Switch Output (PTS)

The Power Transfer Switch Output is a normally open set of contacts that closes two (2) minutes after a power failure is sensed by the TCS22 controller. See the alarm section of this manual for an explanation of the power failure alarm.

The Form "A" contacts are SPST N.O. rated at 24 VAC, 5 A Resistive, or 24 VAC, 2 A Inductive. These rating should not be exceeded under any conditions.

These contacts can be used to energize a power transfer switch when used in conjunction with an

inverter to provide emergency ventilation of the shelter during power failures. Consult the power failure management sequence, section 4.2.10 and section 1.3, for more details.

3.2.4.3 Power Failure Sense Input

The Power Failure Sense is an input into the Controller. A normally open set of contacts is connected across these inputs. When power is lost to the shelter these contacts should close indicating that the building has lost normal utility power.

These contacts can be used in conjunction with an inverter and power transfer switch to provide emergency ventilation of the shelter during power failures. Consult the power failure management sequence, section 4.2.10 and section 1.3, of this manual for more details..

This is a dry contact input only. Do not connect any voltage source to these terminals. Do not connect utility power to these terminals.

3.2.4.4 Fire Alarm Input

The Fire Alarm is an input into the Controller. A set of normally open contacts is connected across these inputs. These contacts should close when fire alarm system has sensed a fire.

This is a dry contact input only. Do not connect any voltage source to these terminals. Do not connect utility power to these terminals.

3.2.4.5 Fire Trouble Input

The Fire Trouble is an input into the Controller. A set of normally open contacts is connected across these inputs. These contacts should close when the fire alarm system senses a problem with the fire alarm system.

This is a dry contact input only. Do not connect any voltage source to these terminals. Do not connect utility power to these terminals.

3.2.4.6 Door Alarm Input

The Door Alarm is an input into the Controller. A set of normally open contacts is connected across these inputs. These contacts
