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.
