Xtralis VPS-215-E Installation And Commissioning Instructions

VPS-215-E & VPS-220-E are power supply units (PSU) for Xtralis Aspirating Smoke Detectors (ASD).
They are compliant with EN54-4:1997+A1:2002+A2:2006.
Location: Site the PSU indoors on a dry, flat surface in an area that is well ventilated. Where possible the panel's indicators (internal and
1
external) should be at eye level and the unit should be installed in the same location as the ASD it powers.
Knockouts: Before mounting, remove selected knockouts with a sharp light tap, using a flat broadsided screwdriver (shown right). Fill knockout
2
holes with good quality cable glands.
Mounting: Mount the metal base securely onto a wall using the four mounting holes provided. Assess the condition and construction of the wall
3
and use No.8-10, or 4-5mm screws. Use the fixing hole template overleaf as a guide.
Wiring: Connect all AC cables BEFORE applying power. Maintain segregation between AC and DC cabling. All wiring should be installed in

accordance with relevant national standards, e.g. IEE Wiring Regulations BS7671 in the UK. Connect the incoming AC to CONN1

overleaf and ensure that earth straps are connected to the earth tag (shown right).
5
Connect DC: Connect the DC output to the Xtralis detector. Examples for the VESDA VLC, VLP and VLF are shown below which may use the General Purpose Input (GPI) to transmit the PSU
fault signal. The VESDA detector must be configured to interpret the GPI input as a 'Mains OK' if this feature is used.

CAUTION: Only use good quality sealed Valve Regulated Lead Acid (VRLA) batteries. There is a risk of explosion if the batteries are replaced by incorrect types.
Commissioning: Switch on the AC supply to the PSU. The OK LED should stay lit and the Fault LED should turn off.

LEDs and relay – see table right.
Normal Operation/Fault Finding: The table in Step 7 provides a summary of the normal operation of the PSU when the battery and/or AC supply fails. When the AC supply fails, the DC output
8
is maintained for at least 24 hours as long as the batteries are in good condition. Damage to the batteries as a result of deep discharge is prevented by turning the DC output off (load shed mode)
when the battery voltage falls below approximately 21V. Should this happen the DC output will not be restored until the AC supply is re-established OR fully charged batteries have been installed.
However, the terminal voltage of the discharged batteries measured after the PSU has entered load shed mode may be greater than 21V because the voltage can recover when the battery is not
under load. Never leave the batteries connected for prolonged periods without an AC supply connected because, during load shed mode, there is a monitoring current Imin (<12mA) which, over
several days, will drain the batteries to the point they are damaged.
