Fire Alarm/Access Control Interface
- Normally Open (NO), Normally closed (NC) input from the FACP or ACP is available to trigger the DKPS-2A operation. Connect the NO or NC from the FACP or ACP output to the FIRE/ACP TRIGGER terminals. Install the 2K2 Ohm end of line resistor (EOLR) provided at the FACP or ACP as shown on the diagram. Fig. 1
REX/Engineering Reset Input
This option is available when the Jumper JL is removed (JL OFF). This will cause the DKPS-2A to latch upon receiving an alarm from the FACP-2A or ACP with this option in place when the FIRE/ACP TRIGGER resets, DKPS-2A will only reset by activating the RESET/REX input.
JL ON will cause the unit to follow the FIRE/ACP TRIGGER. Install the 2.2 Ohms RESISTOR, Part #EOLR-PWX2K2 provided at the Key Switch or push Button to perform this operation.
Reset Output on Power Up
To unlock Maglock on Power Up or total Power Loss, set the programming as follow:
(1) Remove power from the DKPS-2A.
(2) Remove Jumper JL.
(3) Power up the DKPS-2A.
(4) Insert the JL in and out 2 times 1 second apart, and notice the Green LED switching ON.
(5) To reset power to the Maglock Switch ON/OFF the Reset Key Switch for 2 seconds.
To lock the Maglock on Power Up set programming as follow:
(1) Remove power from the DKPS-2A and remove the Jumper JL.
(2) Insert the JL 3 times ON/OFF 1 second apart. Notice the Green LED switching OFF.
Cascade Connection
Two(2) or more DKPS-2A units can be connected together as follows:
Connect the STATUS OUTPUT relay C and NC terminals from the 1st unit to the RESET/REX input of the 2nd unit (not polarity sensitive) and remove jumper JR of the 1st unit. Install 2.2KOHM RESISTOR, PART #EOLR-PWX2K2 on 2nd unit FIRE/ACP TRIGGER. If a 3rd unit is used, JR must be removed from the 2nd unit and so on for any additional unit. Also, 2K2 EOLR must be installed on the 3rd unit and so on. Note: Maximum 20 units allowed.
NOTE: If Latch Mode is used, only JL jumper on the first unit must be removed. Engineering Reset will be performed from the 1st unit.
Installation Instructions
This power supply should be installed in compliance with the National Electrical Code(NFPA 70), CSA C22.1, Canadian Electrical Code, Part 1 and all applicable Local Codes. Installation to be performed by suitably qualified technical personnel.
- Mount the power supply in the desired location using the 4 mounting holes. NOTE: For use in an Indoor Protected Area with Controlled Environment only. Do not install the Power Supply in Exterior Conditions.
- With the Mains power disconnected, connect the leads to the AC Input Terminal Block, respecting the wiring phase and polarity :
Ground/Earth=Green/Yellow, Neutral = Blue (White), Live =Black (Brown). This equipment must be connected to the 100-240 Volt Mains via a readily dedicated accessible external disconnect device with maximum 15 Amp branch protection. Select the operating output DC voltage 12/24 wih the jumper. Jumper ON=12VDC, Jumper OFF=24VDC. - Do not connect the battery at this time.
- Switch ON the AC. The green LED will come ON, indicating AC is present, and the AC Fault Relay will be energized “ON” (closed). When the AC is off, the AC Fault Relay will drop open within 60 seconds (Factory set), activating the CMOS output contact “AC Fail”. Connect this output to relevant monitoring devices.
- Verify the DC output voltage is correct = 13.80VDC or 27.60VDC max. Blue DC LED will be ON to indicate DC output is OK.
- The yellow LED will be on and the BAT FAULT CMOS relay open, indicating the Battery is not present.
- Connect the Battery or Batteries, respecting the polarity. The battery shall not be connected if AC is not present first.
- If the battery is connected with the correct polarities, the Yellow LED will turn OFF (See Table Fault). Within one minute, the Battery Fault Relay will restore (Normally closed). Connect this output to relevant monitoring devices.
- If the battery is connected in reverse polarity, the Yellow LED will be ON. (See the Table Fault). The CMOS relay will open, indicating Battery Fault.
- Connect the devices to be powered to the output terminals +DC LOCK or +DC STRIKE and NEGATIVE(4 outputs). Connect the device to the auxiliary output terminal block -DC+.
- If a Tamper Switch is required, use part # TSW1-02 or TSW2-02, see Fig 3.
- Use EOLR (end of line resistor) Part #EOLR-PWX2K2
- Connect the fault relays to FACP or ACP for trouble indication.
- Secure the enclosure with the provided key lock
