Mircom BPS-802 NAC Power Extender Installation Guide

Mircom BPS-802 NAC Power Extender

Overview

Mircom BPS-802 is an extremely cost effective 8 amp remote power supply/battery charger. It may be connected to any 12 or 24 volt Fire Alarm Control Panel (FACP). Primary applications include Notification Appliance Circuit (NAC such as strobes and horns) expansion support to meet ADA requirements. It also provides auxiliary power to support system accessories. The unit delivers electronically regulated and filtered 24 volt power to Class B, Style W, X, Y or Class A, Style Z NAC loop circuits. Additionally, a separate 1.0A auxiliary output for four (4)-wire smoke detectors is available. The 8 amp max. alarm current can be divided between the four (4) outputs for powering NAC devices. Each output is rated at 2.5 amp max., and can be independently programmed for Steady, Temporal Code 3 or Strobe Synchronization. All outputs may be programmed for Input to Output Follower Mode (output will follow input). An individual output of 4 amp is achieved by paralleling 2 outputs. In non-alarm condition independent loop supervision for Class A, Style Z and/or Class B, Style W, X, Y FACP NAC circuits is provided. In the event of a loop trouble, the FACP will be notified via the steered input (input 1 or input 2). In addition, there are common trouble output terminals (NC, C, NO) which are used to indicate general loop/ system trouble. A common trouble input is provided for optional NC (normally closed) devices to report trouble to the FACP. Two (2) FACP signaling outputs can be employed and directed to control supervision and power delivery to any combination of the four (4) outputs.

| These terminals connect to the 12VDC or 24VDC FACP notification appliance circuit outputs. (Class A, Style Z or Class B, Style W, X, Y) Input trigger voltage is 8-33VDC @ 5mA min.

Terminal polarity is shown in alarm condition. During an alarm condition these inputs will cause the selected outputs chosen to drive notification appliances. The designated outputs are set by output

switches [OUT1 through OUT4] (Output Programming Selection Table, pg. 4). A trouble condition on an output loop will cause the corresponding input to trip the FACP by opening the FACP loop. An alarm condition will always override trouble to drive notification appliances.

RET1+, RET1- RET2+, RET2-

(Supervised)

| For (Class A, Style Z hookups these terminal pairs return to FACP NAC1 and/or NAC2. For Class B, Style W, X, Y hookups the FACP EOL resistor from the NAC1 and/or NAC2 outputs are terminated at these terminals.

| An open across these inputs, will cause the selected outputs chosen to drive notification appliances. The designated outputs are set by output switches [OUT1 through OUT4] (Output Programming Selection Table, pg. 4). Note these inputs are unidirectional and will not report a trouble condition to the FACP.

| Notification appliances are connected to these regulated outputs (see Application Guide pg. 2-4). Each power-limited output will supply 2.5 amp. Two (2) outputs may be connected in parallel for a maximum NAC output capability of 4 amp. Total supply current is 8 amp (see note below). Outputs are controlled by designated input 1 [IN1] or input 2 [IN2] (Output Programming Selection

Table, pg. 4). Maximum line loss or voltage drop (tested with 2.5V).

| An open circuit across this pair of terminals will cause [IN1 and IN2] to simultaneously signal a trouble condition back to the FACP (Typically used to report AC or BAT Fail). (form “C” contact 1 amp / 28VDC) (Fig. 2, pg. 7).
NC, C, NO

(Common trouble output)

| These are dry contact trouble outputs that follow any general loop/system trouble conditions. (Typically used to trigger a digital communicator or other reporting device).

Note: Unit is equipped with 1 amp max. auxiliary output: “AUX” will remain battery backed up during power outage. For loads connected to “AUX” please refer to battery “Stand-by Specifications” above for ratings. When loads are connected to “AUX” output during alarm condition, the remaining outputs may not exceed 8 amp total alarm current (example: AUX = 1 amp, outputs up to 7 amp).

loss AC to local annunciation devices, with AC present terminals marked NO and C are open, NC and C are closed. When loss of AC occurs terminals marked NO and C are closed, NC and C are open.
AC LOCAL NC, NO, C| Form “C” dry contacts used to instantaneously signal the loss AC to local annunciation devices, with AC present terminals marked NO and C are open, NC and C are closed. When loss of AC occurs terminals marked NO and C are closed, NC and C are open.
BAT FAIL NO, C, NC| Form “C” dry contacts used to signal low battery voltage or loss of battery voltage. Under normal conditions terminals marked NO and C are open, NC and C are closed. During a trouble condition terminals marked NO and C are closed, and NC and C are open (Fig. 2, pg. 7).
+ BAT –| Stand-by battery input (leads provided) (Fig. 2, pg. 7).

*Power Board Parameter Specifications:

• AC Fail condition will report approximately 30 seconds after loss of AC. To delay report for 2.5 to 3 hours cut jumper AC DELAY on the Power Supply Board (AC trouble output delay option). If this mode is selected the Power Supply Board must be reset by removing all power to it for 30 seconds.
• Low battery condition will report at approximately 21VDC.
• Battery presence detection will report within 180 seconds after battery remains undetected (missing or removed).
  A restored battery will report within 30 seconds.

LED Diagnostics:

Power Supply Board

AL800LGK9E – Logic Board

• Indicates current trouble condition. When trouble (open, short or ground) occurs on a specific output, the corresponding red output LED, [OUT1-OUT4] will blink. The corresponding green input LED will blink as well. Loop trouble will report within 30 seconds.
  Indicates trouble condition memory. When a trouble condition restores, the unit’s red output LED [OUT1-OUT4] will blink with a shorter and distinctly a different duration. The green input LEDs will be off (normal condition).
  To reset the memory depress the reset button (Fig. 2c, pg. 7). The LED(s) will extinguish.
  Note:** If indicating circuits have been restored, memory reset is not required for normal operation of the unit.

Optional Hookup Diagram

Optional Hookups:

1. Battery and AC monitoring: AC or Battery Fail condition will cause the common trouble input [C “FAULT” NC] to report back to the FACP via input 1 and input 2. The common trouble input may also be used for other optional supervisory monitoring.
   To report AC and Battery Trouble connect the battery and AC Fail relay output shown in (Fig. 2a) to the common trouble input.

2. Dry contact input (C “DRY1” NC) (C “DRY2” NC) can be used to alarm output from an addressable module (these inputs are unidirection and cannot report back to trigger module).
   Connection to triggering devices must be made within 20ft of distance and using conduit for wiring.

3. Auxiliary output (-AUX+) 24VDC at 1 amp max.

4. AC Local [NC, C, NO] should connect to the host control panel for local annunciation of the trouble condition.
   Note: If common trouble input, terminals marked [C “FAULT” NC] are not used, these terminals must be shorted (connect jumper) to remain inactive. For optional hookups see Fig. 2b.

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 (26.2-26.4VDC recommended range).
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.
Fuses: Check fuse on the power supply board, replace if necessary. Input fuse rating is 5 amp @ 250V.
Note: Maximum charging current is 3.2 amp.
Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.
