Altronix AL175ULB Installation Instructions Bedienungsanleitung PDF herunterladen

Overview:

AL175ULB is a power-limited power supply/charger that converts a 28VAC input, into two (2) individual PTC

protected 12VDC or 24VDC output, (see speciﬁcations). They are intended for use in applications requiring UL Listing

for Access Control (UL 294) and applications requiring an interface with Fire Alarm Control Panels.

Specifications:

Power Supply Output Specifications:

Output VDC Switch Position Max. Stand-by Load DC Max. Alarm Load DC Battery (optional)

12VDC SW1 OPEN 1.75 amp 1.75 amp 12VDC

24VDC SW1 CLOSED 1.75 amp 1.75 amp 24VDC

Stand-by Specifications:

Output 4 hr. of Stand-by & 5 Minutes of Alarm

12VDC / 7AH Battery Stand-by = 1.25 amp

Alarm = 1.25 amp

24VDC / 7AH Battery

Installation Instructions:

The AL175ULB should be installed in accordance with article 760 of The National Electrical Code or NFPA 72 as well as

all applicable Local Codes.

See Terminal Identification Chart on page 3 for a description of each terminal function.

1. Mount the AL175ULB in the desired location/enclosure.

2. Connect 28VAC, 56VA transformer to the terminals marked [AC, AC].

Use 18 AWG or larger for all power connections (Battery, DC output).

Use 22 AWG to 18 AWG for power-limited circuits (trigger inputs, dry outputs).

Keep power-limited wiring separate from non power-limited wiring (115VAC / 60Hz Input, Battery Wires).

Minimum 0.25” spacing must be provided.

3. Set the AL175ULB to the desired DC output voltage by setting switch SW1 to the appropriate position

(see Power Supply Output Speciﬁcation Chart, pg. 1).

4. Measure output voltage before connecting devices. This helps avoiding potential damage.

5. Connect battery to the terminals marked [+ BAT -] on the unit (battery leads included). Use two (2) 12VDC batteries

connected in series for 24VDC operation.

Note: For Access Control applications batteries are optional. When batteries are not used, a loss of AC will result in the

loss of output voltage. When the use of stand-by batteries is desired, they must be lead acid or gel type.

6. Connect appropriate signaling notiﬁcation devices to AC Fail supervisory relay outputs.

Note: To meet UL requirements, AC Supervisory outputs must be connected to the zone of Alarm Control Panel

or to visual AC trouble indicator.

7. For Access Control Device & Fire Alarm Interface connections see Application Diagrams, pg. 4

and Terminal Identiﬁcation Chart, pg. 3.
