Figure provides an example. Refer to Section 3. Figure shows the circuit board stack. If you should need to remove the control board for repair, remove the four mounting screws which hold the control board in the cabinet. Then lift the control board out of the cabinet. Read the environmental specifications in section 3. The SK cabinet dimensions are:. The SK panel should be located within a secured area, where it is accessible to main drop wiring runs and where it can be easily tested and serviced.
End-users responsible for maintaining the panel should be able to hear alarms and troubles. When selecting a location, keep in mind that the panel itself is the main source of alarm and trouble annunciation. When mounting on interior walls, use appropriate screw anchors in plaster. A piece of plywood, standoffs, or other equivalent material can be used to space the cabinet from the concrete surface and then attach the SK to that spacing surface.
Water damage to the fire system can be caused by moisture entering the cabinet through the conduits. Conduits that are installed to enter the top of the cabinet are most likely to cause water problems. Installers should take reasonable precautions to prevent water from entering the cabinet. Water damage is not covered under warranty.
The following steps must be taken when determining SK current draw and standby battery requirements. For the SK, the worst case current draw is listed for the panel and panel accessories. Fill in the number of devices that will be used in the system and compute the current draw requirements for alarm and standby.
Record this information in Table at Line A. Add up the current draw for all smoke detectors and record in the table at Line B.
Add up all notification appliance loads and record in the table at Line C. For notification appliances and auxiliary devices not mentioned in the manual, refer to the device manual for the current ratings. Make sure that the total alarm current you calculated, including current for the panel itself, does not exceed 6. This is the maximum alarm current for the SK control panel.
If the current is above 6. Refer to the current draw worksheets provided with the manuals so you do not exceed their power requirements. Complete the remaining instructions in Table for determining battery size requirements.
Copy the page if additional space is required. The SK alarm current includes. Table shows the maximum battery standby load for the SK based on 24 and 60 hours of standby. The standby load calculations of line D in the Current Draw Calculation Worksheet Table must be less than the number shown in Table for the battery size used and standby hours required.
See Section 3. Silent Knight does not support the use of batteries smaller than those listed in Table If you use a battery too small for the installation, the system could overload the battery resulting in the installation having less than the required 24 hours standby power.
Figure shows the AC connections to the SK control panel. To reduce the risk of electrical shock, make sure that all power has been turned off or disconnected before attempting to connect the Model SK control panel. Do NOT apply power to this panel until all accessories are properly connected. In all cases, the authority having jurisdiction takes precedence.
The control panel battery charge capacity is 7. Use 12V batteries of the same AH rating. Determine the correct AH rating as per your current load calculation see 3. Wire batteries in series to produce a volt equivalent. Do not parallel batteries to increase the AH rating.
It is recommended that you replace the batteries every five years. The following steps and diagram explain how to connect the batteries. Connect the black wire to the negative - side of battery 1. Apply AC power before connecting the batteries to the power supply to prevent arcing on battery terminals. Note: The total current draw on smoke power, accessory power, and notification device outputs must not exceed 6A.
The terminal strips on the PC board are non-removable. Table lists the functions of each terminal. The SK connects to two separate telephone lines to report data to the central station. An RJ31X jack should be installed by the telephone company for each line. Figure shows how to wire the telephone line interconnect cords not provided to the SK Note: To reduce the possibility of false alarms and transient damage, DO NOT bundle telephone wires together with initiation or notification device wires.
The letter designator on the phone input indicates whether it is the Telco or House side of the phone circuit. The SK has built-in dual phone line monitors. These circuits will detect any fault in the phone lines by monitoring the DC voltage present on the lines. If phone line voltage drops below 3 VDC and is not corrected within approximately 60 seconds, an audible trouble signal will sound and the panel will report a line fault trouble over the remaining phone line.
A situation could occur where both phone lines appear to be good, but the dialer cannot get through to the central station on the first line.
In this case, the SK will switch phone lines and attempt the call again using the second line. Make sure the phone lines are programmed properly see Section 4. Note: To comply with industry standards, this product is equipped with line seizure. Normally, this condition will last approximately one minute, but under adverse telephone circuit conditions, could last for as long as 15 minutes.
Each class A zone is a four-wire circuit that allows an alarm to be detected even after a single open or ground fault occurs. When a single open or ground fault occurs, the audible trouble signal will sound and the SK will report the trouble to the central station or remote station if programmed to report troubles.
If reporting to a remote station troubles may be transmitted to a secondary location. Figure shows how to wire a Class A Style D circuit. No end-of-line EOL resistors are needed for these.
Zones 3 through 10 are Class B Style B only fire zones. Each Class B zone consists of a two-wire circuit that will detect the occurrence of an open in the circuit, but may not be able to detect an alarm after such an occurrence. The detection of an open will cause the audible trouble signal to sound and the SK will report the trouble to the central or remote station if programmed to do so. Figure shows how to wire a Class B Style B circuit.
One side of each Class B circuit connects to a zone input terminal and the other side of each circuit connects to Smoke power.
For each circuit, use a 4. See also Section 3. Note: Mount the PAM-2 and the end-of-line resistor at the last device on the circuit. See Appendix A for a list of four-wire smoke detectors that may be used with the SK Figure shows how to connect two-wire smoke detectors to Class B Style B zones. See Appendix A for a list of two-wire smoke detectors that may be used with the SK Note: Two-wire detectors can be configured for Enhanced Mode.
Enhanced mode is smoke verification for zones with 2-wire detectors and contact type devices, such as pull stations, used on the same circuit. If the alarm current is greater than 78 mA, the smoke verification cycle will not occur.
See Section 4. Note: To reduce the possibility of false alarms and transient damage, DO NOT bundle telephone wires together with notification circuit wires. For proper operation, you must use polarized sounding devices with a 4. Figure shows how to connect the notification circuits to the SK Contact Silent Knight if you have any questions about compatible notification circuits. All circuit are regulated unless used for releasing service in which case they are considered special applications.
See Section 5. The SK provides four programmable auxiliary relay outputs. Relays can be programmed to activate for the following conditions, either for all zones or by individual zone: pre-alarm not acceptable for NFPA 72 Central Station , fire alarm, auxiliary alarm, alarm by zone, and system or circuit troubles loss of AC, low battery, failed to communicate, phone line troubles, fire drills, and notification circuit troubles.
Refer to the SK programming manual for more information. Figure shows the relay contact connections using a door holder application as an example. All circuits are 24 VDC regulated. Each device must be given its own identification code. On the back of each device is a small 4-position dip switch used to set the ID code. Use the chart below to. ID number 7 and 8 are not valid ID settings. The SK performs all system operation. It also provides trouble and alarm information and can be used for programming.
The control panel can support up to six SK Remote Annunciators. Annunciators with address 0 will not be supervised. The SK Remote Annunciators must be mounted on a dual gang electrical box. To mount the annunciator:. Remove the rear mounting plate by inserting a 4 flat blade screwdriver into the slots on the bottom edge of the annunciator.
See Figure Gently turn the screwdriver until the mounting plate pulls away from the frame. Secure it to the wall using 6 or 8 screws. The mounting plate should be oriented so that the word TOP is toward the top of the plate and facing you. A square hole is provided in the mounting plate to run the wiring to the annunciator. When all of the wires have been connected to the annunciator, set the top of the annunciator over the tabs on the top of the mounting plate.
Make sure the wires do not get pinched between the frame and the mounting plate. Press each corner of the bottom side onto the annunciator mounting plate until you hear it click. You may have to gently squeeze the annunciator top to bottom to align it while snapping the bottom edge into place.
Remove power from the control panel. Wire the SKs as shown in Figure Set the ID number. See Table Reapply power the control panel. When the annunciator powers up, it will display its ID code and current status of the panel. ID DIP switches. Note: Each touchpad can be individually supervised. The Model SK Status Display module provides outputs and control functions for remote annunciation of alarm, trouble, and supervisories for each zone. Note: The driver outputs are non-supervised. Relays must be connected to power limited sources only.
The SK has 1 connector which has 10 outputs for alarms and 10 outputs for trouble annunciation. These outputs are active low.
Each output can provide up to mA of current, with a total limitation of mA. The module has 4 normally open non-dedicated relays that can be wired to be active with any of the outputs. Resets the dialer and aborts the call to central station. Displays the panel history, which includes alarms, supervisories, troubles, reports, time and date changes, etc.
