The beacon shall be located a minimum of three feet above the EPSMS panel. The beacon shall be powered from the EPSMS control panel. The interconnecting wire and conduit shall be included in this scope. The beacon shall be activated when the maintenance override key switch is in the override position.

E.

System Operation

1.

General a.

When the EPSMS receives a second smoke detector alarm signal from the FCP, the

EPSMS shall shut down all 2 nd

Alarm related equipment. After the FCP time delay expires and sends a discharge (water flow if pre-action system only) signal to the EPSMS, the

Discharge equipment shall be shut down. The entire EPSMS shall be equipped with a keyed override switch that disables EPSMS preventing it from shutting any equipment down regardless of any input signals the EPSMS receives. Both local annunciation using indicating LED’s and remote monitoring using dry contacts shall be provided.

2.

Maintenance Override Lock Out Feature a.

The maintenance override feature is critical to proper EPSMS operation in order to prevent the unintended shutdown of equipment when in maintenance override mode and when returning to normal mode after being in maintenance override. The Maintenance Override

Lock Out shall perform the following functions:

1) When the maintenance override switch is in the override position, the 2nd Alarm

Activated, Discharge Activated, and EPO Activated relays shall remain in the normal position (locked out) regardless of the input signals received to prevent accidental shutdown of equipment.

2) When the maintenance override switch is in the override position, if any input signal is received, the corresponding "2nd Alarm Activation", "Discharge

Activation", and "EPO Activation" LEDs shall illuminate.

3) When the maintenance override switch is in the override position, if any input signal is received then cleared, the corresponding 2nd Alarm Activation, Discharge

Activation, and EPO Activation LEDs shall flash indicating the input alarm condition is cleared. The output relays shall remain locked out.

4) Once the maintenance override switch is in the override position, the system cannot be returned to "Normal" without activating the Reset Switch. The Reset Switch

"Unlocks" the maintenance override feature.

5) If the EPSMS panel receives an input signal while in Maintenance Override it cannot be returned to Normal until all input signals are cleared and the panel is





Turlock California reset. This feature provides a second level of protection against accidental equipment shutdown.

F.

Monitoring

1.

The FCP shall supervise the loss of power trouble relay on the EPSMS according to NFPA 75.

H.

Warranty

1.

All system components furnished under this contract shall be guaranteed against defect and workmanship for a period of one year.
