Stand-by Specifications
Stand-by Battery | Current Draw | Stand-by Time | Alarm Time |
---|---|---|---|
12VDC / 4AH Battery | 750mA | 4 Hours | 15 mins. |
Installation Instructions
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, and with all local codes and authorities having jurisdiction. Product is intended for indoor use only.
- Mount the unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes in the enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place the enclosure’s upper keyholes over the two upper screws; level and secure. Mark the position of the lower two holes. Remove the enclosure. Drill the lower holes and install two fasteners. Place the enclosure’s upper keyholes over the two upper screws. Install the two lower screws and make sure to tighten all screws (Enclosure Dimensions, pg. 4). Secure enclosure to earth ground (Fig 1, pg. 2).
- Connect a 16.5VAC, 20VA Class 2, UL Listed plug-in transformer to the terminals marked [AC, AC] (Fig 1, pg. 2).
- Measure output voltage before connecting devices. This helps avoiding potential damage.
- Connect devices to be powered to the terminals marked [– DC +] (Fig 1, pg. 2).
- Connect the stand-by battery to the terminals marked [– BAT +] (Fig 1, pg. 2) (battery leads included).
- Connect appropriate signaling notification devices to the AC Fail and Low Bat supervisory relay outputs
terminals marked [LOW BAT – NC, C, NO, AC FAIL – NC, C, NO] (Fig 1, pg. 2).
Note: To meet UL requirements, AC Supervisory outputs must be connected to the zone of Alarm Control
Panel or to visual AC trouble indicator.
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.
LED Diagnostics
Red (DC) | Green (AC) | Power Supply Status |
---|---|---|
ON | ON | Normal operating condition. |
ON | OFF | Loss of AC. Stand-by battery supplying power. |
OFF | ON | No DC output. |
OFF | OFF | Loss of AC. Discharged or no stand-by battery. No DC output. |
Maintenance
Unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test: Under normal load conditions the DC output voltage
should be checked for proper voltage level (Stand-by Specifications Chart).
Battery Test: Under normal load conditions check that the battery is
fully charged, check specified voltage both at the battery terminal and at the
board terminals marked [– BAT +] to ensure that there is no break in the
battery connection wires.
Note: Maximum charging current under discharge is 500mA.
Note: Expected battery life is 5 years; however, it is recommended
changing batteries in 4 years or less if needed.
Terminal Identification
Terminal Legend | Function/Description |
---|---|
AC/AC | Low voltage AC input (16.5VAC/20VA). UL Listed. Class 2 plug-in |
transformer.
– DC +| 12VDC @ 750mA continuous power-limited output.
– BAT +| Stand-by battery connections. Maximum charge rate 500mA.
AC FAIL NC, C, NO| Indicates loss of AC, e.g. connect audible device or alarm
panel. Relay is normally energized when AC power is present. Contact rating 1A
@ 28VDC.
LOW BAT NC, C, NO| Indicates low battery condition e.g connect audible device
or alarm panel. Relay is normally energized. Contact rating 1A @ 28VDC.
The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of an insulated DANGEROUS VOLTAGE within the product’s enclosure that may be of sufficient magnitude to constitute an electric shock.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.
CAUTION: To reduce the risk of electric shock do not open enclosure.
There are no user serviceable parts inside. Refer servicing to qualified
service personnel.
