16.7 Keypad Speaker Operation
When using LCD Keypads, the panel provides distinct speaker tones from the keypad for Fire, Burglary,
Zone Monitor, and Prewarn events. The list below details the conditions under which the speaker is turned
on and off for each event.
Fire On - Fire zone alarm and Bell Output are ON.
Off - Alarm Silence or briey when a key is pressed.
Burglary On - Burglary zone alarm and Bell Output and is ON.
Off - Alarm Silence or briey when a key is pressed.
Zone Monitor On - One time only when a monitored zone is tripped.
Off - After one tone.
Prewarn On - During Entry Delay.
Off - When Entry Delay expires, when a Valid Code is entered, or when a key is pressed.
16.8 Cross Zoning
Caution must be taken when cross zoning devices to ensure that the Cross Zone Time is long enough to
allow an intruder to trip both devices before it expires. A Cross Zone Time that is too short may allow an
intruder to trip the devices and allow only a zone fault report be sent to the central station.
When a Cross Zoned zone trips, a FAULT report is sent to the SCS-1R Receiver. When two Cross Zoned
zones trip within the Cross Zone Time, both zones send ALARM signals to the receiver. For example,
if zones 1 and 2 are Cross Zoned zones, and only zone 1 trips, a FAULT report is sent to the receiver
for zone 1. If zone 1 trips and zone 2 trips within the Cross Zone Time, an ALARM report is sent to the
receiver for zone 1 and zone 2.
Note: To operate correctly, all cross-zone zones need to be programmed as the same zone type.
