Emergency Shunt Trip Relay

The wattstopper elcu 200 emergency lighting control unit is a self contained device that allows any standard lighting control device to control emergency lighting in conjunction with normal lighting in any area within a building.

Emergency shunt trip relay.

The normally closed relay in the ul924sr1 ul924sr2 connects to the line and load side of the control device. Whereas designated and alternate elevator recall captures and sends the elevator cab to safe floors elevator shunt trip works a little different. This slim unobtrusive device converts regular light fixtures to approved emergency lights and can be flush or grid mounted. When normal power is present the esr relay coil is activated and the emergency panel is fed from normal power.

Hubbell control solutions enclosed bypass shunt relays are typically used to bypass a normal control such as a switch dimmer or panel mounted relay when used on an emergency circuit. During normal operation the same 0 10v dimming system dali control device occupancy sensor relay panel or lighting control device can dim or switch regular and emergency fixtures on and off simultaneously. The coil in these relays is powered by a normal power supply. Ul924 emergency lighting relays.

Ul924 enclosed 20 amp bypass shunt relay our enclosed 20 amp electrically held ul 924 bypass shunt relays provide an isolated normally closed contact that can be used to bypass control devices to power emergency lighting directly from the emergency generator. Emergency shunt relay by lighting controls design. Manually controlled emergency lighting will be automatically shunted on during a power outage the emergency shunt relay comes in a two gang junction box with a voltage separating barrier and is shipped with a. Our ul924 emergency lighting relays can be used for automatic load control or bypass shunt applications to turn on emergency lighting in the event of the loss of normal utility power.

Emergency lighting can be controlled under normal conditions using the wall switch input. Elevator controls play a huge role in fire alarm system emergency functions. So our neutral will be connect direct to the shunt tripping coil and phase hot wire will be connect to coil other side through the epo push button. In automatic load control applications when normal power is present the esr relay coil is activated and the emergency panel is.

Shunt relay application our emergency bypass shunt relays are ul924 listed and suitable for shunting around wall switches in order to turn on emergency lighting in the event of loss of normal utility power. Elevator shunt trip is a function that involves shunting the breaker that controls the elevator equipment prior to the release of the automatic sprinkler systems. A two second self test of the unit is performed every time the wall switch input is turned off. Normally closed electrically held relay to be wired in parallel with a wall switch.

If power is lost for any reason including the tripping of a single branch circuit breaker the elcu 200 will force on the emergency fixtures for that area.
