SECURITRON LCP SERIES ELECTRIC LOCK CONTROL PANEL

INSTALLATION AND OPERATING INSTRUCTIONS

1. DESCRIPTION

1.1 GENERAL

The LCP series is a circuit board based family of control panels suitable for hard wired control and monitoring of electric locks. The unit can also be used for door monitoring only (no electric locks). See section 6. The circuit board operates 4 control/monitoring zones so the panel must be constructed in multiples of 4 zones. The locks must operate on 12 or 24 volts DC and may be fail safe (secure when powered) or fail secure (secure when unpowered). Lock current draw is limited to 1.5 Amps (steady) with 3 Amps inrush acceptable.

The LCP series includes several options which are generally supplied with the panel (when ordered) or in most cases may be added by the installer if the requirement for the option is discovered after the panel has been delivered.

The panel's part number expresses the complete description of the panel as follows: LCP-XX-YY-(OPTIONS) "XX" = The number of zones for control and monitoring

"YY" = The panel voltage (12 or 24 VDC) Options are expressed as letter suffixes as follows: "W" = Wall mount Nema 1 locked enclosure

"F" = Flush mount pull box cover with back box "R" = 19" Rack panel face. A slope front desk mount is the standard panel enclosure. "SL" = Silence Latch "PB" = Emergency all release (for fail safe locks only) "AM" = Additional set of monitoring lights "KP1" or "MK1" = Keyswitch control switch bypass (for fail safe locks only) "KP2" or "MK2" = Keyswitch control switch bypass (for fail secure locks only) "MOM" = Momentary control switches (alternate is standard) “HT” = Substitutes high volume push button switches for toggle switches

As an example, part # LCP-16-12-W-SL-MOM would be a 16 zone, 12 VDC, wall mount panel with the Silence Latch and momentary switch options installed.

The options are discussed in detail in section 2.

1.2 PANEL POWER

Panel (and lock) power must be from a single power supply of the same voltage required by the locks (12 or 24 VDC). The panel distributes this power to each lock through its control switches. Regulated DC is not necessary. A transformer + bridge rectifier is adequate. The rectifier

must however be full wave; a single diode will not work.

A power supply with integral battery backup (available from Securitron) is required if the system is expected to operate in a power failure.

In selecting the power supply, it naturally should be of sufficient capacity to operate all the locks. In addition the panel requires power for its internal electronics and indicators. The power

Rev. A.1, 10/99 Page- 2

requirements vary with the monitoring scheme and the voltage but figure a worst case of 60 mA per control zone for panel current draw. Since power supply cost is always a small percentage of the installation cost, we always recommend to not skimp on power supply capacity. We advise that the power supply be capable of driving 30% more current than the installation requires. This eliminates heat induced power supply failure and also allows for some future expansion of the job.

1.3 LOCK CONTROL

Each lock is controlled by a toggle switch on the panel face. Normally, the toggle switch is alternate action but the "MOM" option supplies spring loaded momentary toggle switches so that the lock will be released only so long as the switch is held down. It is, of course, possible to control multiple locks from a single switch (zone) if they are wired in parallel. This is most commonly done with two locks mounted on a double door. Be sure that if multiple locks are controlled by a single toggle, the 1.5 Amp current limit per zone is not exceeded. If higher current control is necessary, the panel should be made to control a relay which in turn will switch the high current lock or locks. Note that toggle switches are not suitable for high volume use. 50,000 cycles is a typical operating life for a toggle switch. If your expected use for each zone is on the order of a few dozen operations per day, toggle switches are fine. If the expected use is in the hundreds of operations per zone per day, you should purchase option HT which replaces the toggles with illuminated push buttons with a much longer operating life. The lamp within the “HT” push button, operates just as the toggle bat yellow indicator.

1.4 MONITORING

Each zone (toggle switch) has a bicolor LED with green and red internal elements behind a fresnel

YELLOW LED (AM OPTION ONLY)

lens. If a second indicator is present for each toggle, this is the "AM" option which is described in section 2.3. Returning to the bicolor indicator, the green element is driven by a separate input terminal on the board and it is intended to monitor the status of the lock or door. Green indication means that the lock is reporting secure if it has lock status sensing or it can mean that the door is closed from a door switch. If no lock or door monitoring is desired, the

BICOLOR LED (GREEN/RED)

LOCK SECURE TOGGLE POSITION TOGGLE BAT YELLOW LED

LOCK RELEASE TOGGLE POSITION

green indicator can be made to follow the powered/unpowered status of the lock although this does not utilize the full capabilities of the panel.

When the lock has been "legally" released from the panel toggle or from a local switch at the door such as a keyswitch, digital entry device or card reader, the bicolor indicator will be off.

Each toggle switch has a yellow LED in its actuator. This illuminates whenever the lock is legally released, either from the toggle switch itself being flipped down, or from a local release switch at the door. The yellow toggle indicator will always correspond to "bicolor indicator off".

If the panel has been supplied with spring loaded momentary switches (option "MOM"), the toggle switch will not have any indicator due to unavailability from the switch

manufacturer. The bicolor indicator will turn red in the "violation" condition. This is when the lock should be

secure but is not so reporting from its lock status or door status output.

Rev. A.1, 10/99 Page- 3

1.5 AUDIBLE ALARM AND ALARM RESET

The red indicator is always accompanied by a Sonalert sounding on the panel. The panel operator hears the alarm, and then consults the panel face to determine the zone that has gone into violation. The violation condition is latching. Once a red indicator goes on and the Sonalert sounds, it will continue even if the door is resecured, until manually reset by the momentary reset switch on the panel face. This reset switch serves for any violation event on the entire panel.

The panel's reporting of a violation event is automatically delayed by 2 seconds. To understand the purpose for this, consider a typical installation with lock status sensing locks. When a lock is legally released by the panel toggle or a local switch, the panel reports legal release (toggle bat LED yellow and bicolor LED off). When the lock is resecured by the same switch, some time (usually a half second) is required for the lock to report secure to the panel. This is the time necessary for a magnetic lock to pull in and generate full holding force or for a bolt to seat. Without the violation delay, a latching alarm event would occur every time a zone was relocked.

If the factory is informed, the delay time can be increased to up to 6 seconds (capacitor values on the boards are changed). An example of a longer delay being desired would be if entry was by a keyswitch. A person using the door would turn the momentary keyswitch and push the door open with his other hand. A 6 second violation delay would be appropriate to allow the person to release the keyswitch, move through the door, and then allow the door to reclose and resecure. Note that if the keyswitch activates a release hold timer as is commonly done, a long delay is not required. The timer will shunt the panel violation condition allowing the door to reclose. When the timer resecures the lock, it will drop out the violation shunt and only a short delay will be necessary to allow the lock to report secure again.

The effect of the bicolor LED in helping the panel operator correctly reset panel violations should be understood. In normal operation, the locks are secure and the indicators are green. Legal use of the door switches the bicolor LED off and it then turns green again when the door resecures. If the indicator turns red (accompanied by the Sonalert) a violation has occurred which means that the door is not secure. If reset is attempted at this point, the Sonalert will stop but after the alarm delay expires, (2 seconds) the violation condition will reoccur as the door is still not secure. If the panel toggle is switched to legally release the lock, the violation can now be reset (bicolor LED will be off) but the door is still not secure. The panel should be reset after the door has been resecured. At this point, the bicolor green element (door secure) and red element (violation) will both be lit which will make the LED appear orange. The orange color is

therefore the signal to the operator that the zone is secure after a violation and is ready to reset.

2. OPTIONS

If the panel has been supplied with any of the options listed in section 1.1, explanations of the options' functions are provided in the following sections. Section 5 explains wiring for all options including the addition in the field of certain options that may not have been ordered with the panel but have turned out to be needed at the time of installation.

2.1 SILENCE LATCH (OPTION "SL")

In the event of a violation condition which takes some time to resolve, the continuing Sonalert is irritating. If the "SL" option has been installed, the sound can be extinguished by momentarily pushing the "silence" button found next to the Sonalert. This works as follows: If the Sonalert is not sounding, pushing the button has no effect. The Sonalert cannot be silenced in advance. When it is sounding, pushing the button will stop it and illuminate the indicator in the button which shows the silence latch is active and the Sonalert would otherwise be sounding. The red indicator will continue to show the zone in violation. The Sonalert will remain silent until the violation condition has been reset even if another zone violates. The button indicator will then extinguish and the latch will reset. The next time a violation condition occurs, the Sonalert will again sound and may again be silenced as before.

2.2 EMERGENCY RELEASE (OPTION "PB")

Often, for safety reasons, it should be possible to release all locks with a single control. The "PB" option adds to the panel an illuminated, alternate action, red push button switch. In normal operation, the red indicator in the switch is off. When the switch is pressed, it cuts off all DC power to the locks, releasing them (the "PB" option works with fail safe locks only). The red indicator in the switch then illuminates showing that the panel is in a state of emergency release. Pressing the switch a second time extinguishes the indicator and restores power to the locks.

Note that when this happens, the Sonalert will sound and the reset switch will have to be pressed. Whenever the panel boards are first powered or repowered, the reset switch must be

pressed to initialize the boards and start normal operation of the violation circuit.

2.3 ADDITIONAL MONITORING LIGHTS (OPTION "AM")

The "AM" option adds a second row of LED's (yellow) next to the bicolors. When a positive voltage signal is input to the associated board terminal, the yellow LED comes on. At the same time a different audible alarm sounds. For panels with the "AM" option, Securitron uses a dual input Sonalert. It sounds a steady alert in the violation condition but sounds a pulsing alert if any panel yellow LED illuminates. The pulsing alert can not be silenced with the silence latch if that option has been supplied.

The main purpose for the additional monitoring capability is exit delay installations. In such installations an exit device is mounted on each door. Pressing the exit device does not immediately release the lock, but rather initiates a 15 or 30 second delay after which the lock automatically releases. A specialized logic timer such as Securitron's model XDT is necessary to accomplish the delay function. When a control panel is used in this sort of installation, the start of the release delay period must be annunciated so that a guard can be dispatched to the door to investigate the egress attempt. The yellow indicator together with the pulsing Sonalert perform this function.

Rev. A.1, 10/99 Page- 5

It is, of course, possible to assign a different function to the additional lights. They can be made to illuminate when any sort of external switch closes. Examples could include an installation where lock status and door status are separately monitored. If it is desired that the pulsing Sonalert not accompany the illumination of a yellow LED, it is a simple matter to disconnect the +V line to the Sonalert's pulse input.

2.4 SWITCH BYPASS KEYSWITCH (OPTIONS "KP1", "KP2", "MK1", "MK2")

With this option, an alternate action keyswitch is mounted on the panel face with an LED indicator to show its position. When the indicator is on, the panel is in the normal operating mode. All the toggles function to release and secure the locks. When the keyswitch is turned, the panel is bypassed. This means that all locks are immediately secured (if some had been released from the toggles) and the toggles will no longer release any lock. If fail safe locks are being used and the PB (emergency release) option has been supplied, the push button will also not be able to release the locks. The purpose for this is allow a panel operator to leave the panel for a time without the danger that an unauthorized person will release some of the locks.

There are 4 possible configurations for the switch bypass option. KP calls out a tubular Ace type keyswitch. MK calls out a mortise cylinder type keyswitch wherein the user supplies the cylinder and the unit is delivered with a hole for mounting the cylinder. Rear bracketry includes the actual switch which is operated by the cylinder cam. This permits the user to key the panel bypass keyswitch into his facility keying system. The KP1 and MK1 versions are for fail safe locks. When they are in the bypass position, power is sent to the locks in a manner that bypasses the toggles and emergency release button (if one is present). The panel continues to monitor the doors but power cannot be removed from the locks by the panel. The KP2 and MK2 versions are for fail secure locks. When they are in the bypass position, power is removed from the panel boards so that the locks stay secure. With this approach, the panel stops monitoring the locks as the boards have been unpowered. Note that for the fail secure version, an emergency release button is not available.

Do not employ this option in a delayed exit installation with Securitron’s XDT board. It will not work properly. See Section 5.3.

2.5 MOMENTARY SWITCHES (OPTION "MOM")

This option supplies spring loaded momentary toggle switches for lock control. The normal position is lock secure. The switches are momentarily pressed to release the lock. Note that when momentary switches are supplied, the yellow toggle bat LED indicator is eliminated due to unavailability from the switch manufacturer. All other features of the panel are the same. Since "toggle bat indicator on" annunciates the same condition as "bicolor off", the monitoring performance of the panel is not lessened. Note that on a special order basis, momentary and alternate switches can be mixed on the same panel.

2.6 HIGH VOLUME PUSH BUTTONS (OPTION "HT")

In “normal” use, toggle switches are appropriate for the LCP. They have the advantage of showing their position by facing up (locked) or down (released). Toggles, however, are not intended for high traffic use. Their typical operating life is roughly 30,000 cycles. This is well adequate for most applications when the toggles are used occasionally but where the panel switches are being continuously employed for letting people through doors (this is often a momentary application), the “HT” option substitutes push button switches for the toggles. The push button switches have many times the cyclic life of the toggles. They also include internal indicators which operate just as the yellow bat indicators do on the toggles. The use of the “HT” option does not change any panel wiring procedures and note that the option “MOM” can be combined with the push button “HT” option to yield momentary operation rather than the standard alternate action.

TERMINALS "+1, +2, +3, +4”: They constitute the +V inputs for zones 1, 2, 3, and 4. In most installations,

these four terminals wire directly to the +V output of the power supply and are therefore jumped together. The fact that they are separate on the board, however, allows the use of upstream switches to individual zones.

TERMINAL "-”: This is the DC negative input for the board. TERMINAL "R": This is the violation reset input. It is prewired through a momentary N.O. toggle reset switch.

When the Sonalert sounds, accompanied by a red indicator, the violation condition (lock not secure when it should be) has occurred. Once the violation condition has been corrected, the Sonalert will continue to sound as this is a latching condition. Pressing the reset toggle supplies +V into this terminal and the condition will reset. All R terminals on all the board used in the panel are wired together. A single reset toggle serves to reset a violation on any board in the entire panel.

TERMINAL "A": This prewired output supplies +V to drive the Sonalert when a violation condition has

occurred (after a 2 second delay). All A terminals from all panel boards are wired together so that any of them can operate the single Sonalert.

Rev. A.1, 10/99 Page- 7

TERMINALS "Y1, Y2, Y3, Y4": These input terminals are only active if the AM option has been supplied.

With the option, a second (yellow) LED will be mounted adjacent to the standard bicolor. When the respective "Y" terminal receives +V, the yellow LED will illuminate. This is used to annunciate any condition monitored from a dry contact closure or voltage signal. Most commonly, the yellow LED annunciates the beginning of delayed exit for a door but other purposes are possible.

TERMINAL "AY": This is a +V voltage output that is on when any Y terminal is on (illuminating the yellow

LED). It is active only when the AM option is supplied. It is prewired to drive a pulsing Sonalert so that when any yellow LED illuminates, it will be annunciated with a distinctive sound. With multiple boards in a panel, all AY terminals wire together with a single wire from any one going to the pulse Sonalert input. If the user wishes to disable the AY audible alert, this single wire may be cut.

TERMINALS "S1, S2, S3, S4": These input terminals illuminate the green side of the respective zone

bicolor LED when they receive +V. They are connected to lock or door status output such that closed or +V = secure for the zone. In the normal condition of the panel, the zones are secure, the bicolor LED's show green and the S terminals receive +V.

TERMINALS "L1, L2, L3, L4": These terminals supply +V when the respective toggle switch is in the on

position (points toward the LED). They are connected to fail safe locks. If fail secure locks are employed, these terminals are used only when status or remote release switches are present on the zone. The L terminals are used to power the switch commons.

TERMINALS "E1, E2, E3, E4": These terminals are both an input and an output. When the respective

toggle switch is off (points away from the LED), the terminals supply +V to release a fail secure lock. At the same time, the yellow indicator in the toggle switch bat illuminates (this annunciates "legal release" of the lock). Also the violation condition of the zone is shunted. While the lock is legally released (toggle off; bicolor off; toggle bat yellow LED on), the zone will not violate. As the lock status input (S terminals) reports insecure (since the lock has been released), the green bicolor indicator will go off but the red side will not come on as would be the case if the respective E terminal did not have +V on it.

As stated above, turning the toggle off puts +V on the E terminal. The same can be accomplished from a remote switch. If, for instance, a remote release switch sends power to a fail secure lock, it will "legally" release. This will input power to the E terminal as it is already connected to the lock. The yellow indicator in the toggle bat will light up even though the toggle remains in the on position and the violation condition will be shunted.

Annunciating legal release and shunting zone violation is also accomplished with a fail safe lock. The fail safe lock connects to the L terminal. A remote SPDT switch can legally release it. The common and NC contacts break power to the fail safe lock, but the NO contact is wired back to the E terminal. When the fail safe lock is therefore remotely released by this switch, the respective E terminal receives +V and the toggle bat indicator lights up annunciating the condition and shunting the violation.

4. WIRING

4.1 POWER INPUT WIRING

The board requires a source of DC voltage which it distributes to the locks. +V from the power supply is input to terminals +1, +2, +3 and +4. If the power supply you are using has a single DC output, the +1 through +4 terminals should be jumped together. They are individually used if the power supply has multiple breakered outputs or if you are employing upstream switches to deactivate any of the panel zones. Negative voltage from the power supply is always input to terminal “-”. Note that four wires are typically required to be run to each door unless Securitron’s XDT board is being used in a delayed exit installation. Then six wires are required.

Figure 2, below, shows the hookup where you jump together the positive terminals (on the left) and use of the positive terminals individually with a Securitron power supply that employs a CCS

Rev. A.1, 10/99 Page- 8

board. The CCS board provides multiple, current limited two Amp outputs on terminals marked P1, P2 etc. The advantage of using these individual outputs as shown on the right of Figure 2 is that any short circuit in the downstream wiring will take out only one of the breakers on the CCS board and the rest of the installation will continue to operate. Use of a multiple output Securitron power suppy materially increases the reliability of the installation and is therefore recommended. Note however that you can always add in-line fuses or breakers to any single output power supply to create the effect of the Securitron supply with CCS board.

On both examples shown in Figure 2, note that there is a red flying lead from the underside of the reset toggle. This wire simply supplies +V to the toggle common and then, when the spring loaded toggle is pressed, +V is input to the “R” terminal of the board which is used to reset the violation alarm function. The red flying lead requires constant +V so that the panel violation alarm can always be reset. The reason why the factory doesn’t connect this wire is that when individual breakered outputs or ‘upstream” switches are used to operate the “+” terminals on the board (shown on the right of Figure 2), constant +V cannot be guaranteed to any “+” terminal. Therefore, as Figure 2 shows, when you have only a single source of +V, connect the red flying lead to any of the “+” terminals (they will all get constant power). When you can employ individually breakered +V outputs (right side of Figure 2), connect one of the breakers separately to the red flying lead in order to guarantee that it will always have power on it. Supposing that you have to choose between putting two panel zones on one breakered “P” output terminal or sharing a breakered “P” terminal between a panel zone and the red flying lead, it is better to do the former. The panel user will expect to always be able to reset a violation alarm even if one of the panel zones is de-powered from a short circuit or other condition.

Note that often the number of panel zones exceeds the number of “P” terminals in the power supply. Each “P” terminal can power multiple “+” input terminals so long as the current rating of the “P” terminal is not exceeded. This in turn depends on the voltage and the type of lock being
