505-12 Power Supply

Description

The DMP 505-12 Series Power Supplies are regulated, power limited, switching power supplies. The 505 Series are rated for 12VDC @ 5 Amps maximum. Each power supply includes a transformer, battery leads and is mounted in an enclosure. Each power supply provides connections for AC input, DC output, and a standby battery. Also included are a low AC input LED indicator, a low standby battery LED indicator, AC trouble and battery trouble relays, and on-board transient protection for the AC input and the DC output. The 505-12LX includes two Model 867 Style W

Notication Modules.

Mounting the Enclosure

Mount the power supply metal enclosure in a secure, dry location to protect the unit from damage due to tampering or the elements. It is not necessary to remove the PC board or transformer when installing the enclosure.

Enclosure 505-12/505-12LX

Material 20-gauge, cold-rolled steel Colors Gray (G) or Red (R) Dimensions 15.75” H x 12.5” W x 4.75” D

Enclosure 505-12A

Material 18-gauge with 16-gauge door Colors Gray (G)

Dimensions 17.5” W x 13.5” H x 3.75” D

Mounting Optional NAC Modules

The power supply enclosure can accommodate the addition of two NAC modules for powering various listed

notication appliances. Use either the DMP Model 865 conventional Class A NAC module, the Model 866 conventional

Class B NAC module, or the Model 867 LX-Bus NAC module. Install any of the modules inside the enclosure using the

three hole mounting conguration. Plastic standoffs are provided with each module that attach to the enclosure.

See Figures 1 and 2.

Wiring

AC Connection

Connect the transformer to an unswitched 120VAC 60 Hz power source with at least 1.5 Amps of available current.

In Figure 1, connect AC power to the transformer Black and White ying leads. In Figure 2, connect AC power to the

terminal block. Always secure the green wire lead to earth ground.

Note: Use 18 AWG or larger for all power connections. Ensure there is a minimum 0.25" space to keep power limited

wiring separate from non-power limited wiring (120VAC/60 Hz input, battery wires). The power supplies must be properly grounded before connecting any devices or applying power to the unit. Proper grounding protects against electrostatic discharge (ESD) that can damage components.

Battery Connection (J3)

Connect the black battery lead to the battery negative terminal. Connect the red battery lead to the positive battery terminal. Only use sealed lead-acid batteries and replace every 3 to 5 years.

Note: Observe polarity when connecting the battery. Only use sealed lead-acid batteries and replace every 3 to 5 years.

AC and Battery Trouble Relay Connections (J4)

Connect AC TRBL and BATT TRBL supervisory relay outputs marked NC (normally closed) and C (common) to a control panel or an 867 NAC zone. Relays are form C with the contacts rated at 30VDC. When an AC trouble or Battery trouble occurs, the relay contacts switch from the NC (normally closed) to the NO (normally open) position. When connected to a panel, an alarm sounds. When connected to an 867 NAC the LEDs turn off as listed in the table below.

DC Output (J6)

Connect devices that require power to output terminals marked — DC +. Note: Measure and verify output voltage before connecting devices to ensure proper equipment operation.

Standby Battery Power Calculations

The following calculation denes the total number of Amp-hours required. From this calculation, assemble the

appropriate number of batteries to slightly exceed the calculated total Amp-hour requirement.

1. Add all standby current values including the power supply operating current.

2. Multiply the total standby current by the number of standby hours needed.

3. Add all alarm current values and multiply by 0.25.

4. Add the total alarm mA-hour with the total standby mA-hour and then multiply this number by 0.001.

1. Total Standby Current = _____ mA Number of Standby Hours Required x _____ hr

2. Total Standby mA-Hours Required = _____ mA-hr

3. Total alarm current x .25 = _____ mA

4. Total Required Amp-hours = _____
